117: Twenty Out Of Twenty Is Bad

Darryl Thomas & John Sextro — Wed, 24 Aug 2016 16:15:00 GMT

Discussion: Energy Profiler

For more info see Ep. 104, Power Struggles

Apple really wants us to be good citizens of the battery.
Apps that quickly drain the battery will be shunned by users
- Remember the Facebook background audio “bug” (some say ploy to allow the fb app to stay alive in background)
“App as patient” metaphor
iOS Energy Gauge / Energy Report
- provides a high-level overview of energy usage as you test your app
Energy logging on phone
- Good for long periods of data collection
Energy Instrument
- for best results, target an iOS device wirelessly (I wasn’t able to get this working because you need Bonjour and multicast enabled on your wireless network access point)
- 20 / 20 is bad, 1 / 20 is good
Energy experts at Apple recommend
- Do it never (Do it less)
- Do it later
  - Use the background activity scheduler APIs
- Do it more efficiently

116: Jittery Moment

Darryl Thomas & John Sextro — Wed, 10 Aug 2016 15:00:00 GMT

Discussion: Time Profiler

But first: a brief rundown of the Instruments UI
- Toolbar
  - Record/Stop
  - Pause
  - Target Selection
  - Status display
  - Strategy Selection
    - CPU data
    - Instrument data
    - Thread data
  - Detail/inspector toggles
- Timeline
  - Plots data along the time your app was sampled
  - Can be filtered and zoomed
  - Disclosure arrow can toggle display of just the current run or of all runs in the trace document
- Detail
  - Contents vary by Instrument, but this will generally be a table with some representation of the sampled data
- Inspectors
  - Record Settings
  - Display Settings
  - Extended detail (often the heaviest stack trace)
What is Time Profiler?
- An Instrument providing sample-based analysis of an application’s activity
- Periodically samples the call stack to determine where an app is spending its time
  - These are instantaneous samples. They don’t track the duration of a function call, but rather how many times when sampled was the application currently in said function call.
  - No distinction between a fast function called many times and a slow function called few times
  - Extremely fast functions may not get sampled at all, if they happen to occur in between samples
- Provides a detail view listing call trees, optionally separated by thread and/or state, allowing the developer to drive down into calls to identify areas that may need to be optimized
  - Weight - Percentage of samples in which a function appeared and an aggregate summary of samples (count * sample interval)
  - Self Weight - Aggregate summary of samples in which the function was at the top of the call stack
  - Symbol Name - The thing represented in the current row (may be a function, method, closure/block, thread, or app)
  - Category
  - Additional columns available:
    - Count
    - Self Count
    - Library

115: Do the Weak-Strong Dance

Darryl Thomas & John Sextro — Wed, 27 Jul 2016 16:30:00 GMT

Discussion - Allocations and Leaks instruments

Extraordinarily hard to spot
Tough to find offending code without help from tools
Unbounded Memory Growth (memory growth without a chance to collect (deallocate) memory
True Leaks (retain cycles)
Allocations
- Generation Analysis
- Tracks allocations still resident when the generation is marked
```
  - As you do multiple generations you will see only the new allocations since the last generations
```
- Simulate Memory Warning (did it help, do you have anything observing for this?)
- I have unbounded memory growth, now what?
```
  - Look for the biggest offenders (sorting)
  - Drill into the code and look for ways to release unnecessary allocations
```
- Good ‘ol fashion memory management
- If you’re intentionally holding onto objects, consider implementing an observer for UIApplicationDidReceiveMemoryWarningNotification to release them
Leaks / Retain Cycles aka. Strong Reference Cycles
- Persistent vs. Transient
- Static Code Analyis
- Narrow list to your code
- Use / Observe (detective work)
- “You’re in the ballpark” now what?
  - Reference counting
  - Weak and Unowned
    - Closure example with capture list; weak and unowned
  - Apple says, “Use a weak reference whenever it is valid for that reference to become nil at some point during its lifetime. Use an unowned reference when you know that the reference will never be nil once it has been set during initialization.”

114: It's All Unified

Darryl Thomas & John Sextro — Wed, 13 Jul 2016 18:15:00 GMT

Discussion - Notifications in iOS 10

Brief breakdown of WWDC sessions related to notifications
New stuff
- APNS Token-based authentication
- UserNotifications (and UserNotificationsUI) Framework (Unifies Remote and Local Notifications)
- Access to user-defined notification settings
- Expanded content
  - Titles
  - Subtitles
  - Media attachments
- Scheduling and handling within Extensions
- In-app presentation
- Removal/update of pending notifications
- Dismissal actions
- Service Extensions
APNS Token-based authentication
- Uses JSON Web Tokens (libraries widely available to assist with token generation)
- For server-side solutions where using a certificate isn’t practical/feasible
- Addresses issue of certificate expiration (though tokens also expire, new ones can be generated on the fly)
UserNotifications Framework
- Provides a single notifications API across iOS, watchOS and tvOS
  - iOS: Full support for scheduling and management of notifications
  - watchOS: Support for forwarded notifications and local notifications on the watch
  - tvOS: Support for badging app icons
- Key components/concepts:
  - UNUserNotificationCenter
    - Authorization requests
    - Scheduling via requests (by providing content and triggers)
  - UNNotificationRequest
    - Identifier
    - Content
    - Trigger
  - UNMutableNotificationContent
  - UNNotificationAttachment
    - Audio
    - Images
    - Video
  - Triggers
    - Push (UNPushNotificationTrigger is not instantiated by apps)
    - UNTimeIntervalNotificationTrigger
    - UNCalendarNotificationTrigger
    - UNLocationNotificationTrigger
  - UNUserNotificationCenterDelegate Protocol
    - userNotificationCenter:willPresentNotification:withCompletionHandler:
    - userNotificationCenter:didReceiveNotificationResponse:withCompletionHandler
  - UNNotificationCategory - defines a type of notification, allows actionable notifications and content extensions
  - UNNotificationAction - represents a task you can perform in response to a notification
  - UNNotificationServiceExtension - Entry point for service extensions. Allows you to process the payload of a push notification before it is presented (eg: end-to-end encryption or notification attachments). Use in conjunction with “mutable-content: 1” in the aps portion of an APNS payload.
UserNotificationsUI Framework
- Provides the UNNotificationContentExtension protocol
- View controllers adopt this protocol, using the VC’s view to display the notification contents
- Custom content is sandwiched between a header with the application icon and title and the default notification payload (default payload can be hidden using an attribute in the Info.plist)
- No user interaction
- Actions are displayed and extensions can respond to them by intercepting action responses
- Protocol provides a didRecieveNotification: method you can use to set up UI in response to the notification

Swift 3.0

To be available later this year

  * [Winding Down the Swift 3 release - Chris Lattner](http://thread.gmane.org/gmane.comp.lang.swift.evolution/17276)
      * New “blue sky” proposals will be considered for post-3.0 development (~August)
      * Generics features (among other dependencies) are preventing the previously-planned ABI stability
      * ABI stability will come in a later release and is considered of “highest priority”

CareKit
- Why use it?
  - enable people to actively manage their own medical conditions through app-based care plans, and symptom and medication monitoring, while sharing insights with care teams and others you trust
  - Examples:
    - Surgery recovery app
    - Depression treatment app
    - High blood pressure treatment app
- What is it?
  - open source framework
  - can integrate with ResearchKit
  - able to access HealthKit data, when granted permission
- ((Opinion)) Why the focus from Apple on Health Apps? Is this a legacy from Steve Jobs?
- Components of CareKit
Care Card
Symptom and Measurement Tracker
Care Plan Store

Discussion

Testing normal networks (aka, not the US)

62.5% of the world’s 3.2 Billion internet users have 2G connections (or worse). That number is growing. LTE speeds aren’t going to catch up for at least a decade if not much longer.
When building robust networking between your client apps and your services, the common case should be the default case. AKA: not WiFi and not LTE.
Things that help a great deal:
- Test on 2G and flaky networks
  - Helps to do real world testing in parking garages, elevators and in transit.
  - Simulation will be the highest reproducible ROI way to test
- Fail fast and accurately. Timeouts play a part in this.
- Be dynamic with how you handle the network.
  - Slower speeds should have less networking
- Use modern tech, like HTTP/2
- Defer, defer, defer (and prioritize)
- Robustly handle errors
  - If at first you don’t succeed, try again! And again and again. Retry policies can get you from one-9 of success to three-9s very simply.
- Design your network API in a robust manner!
Simulating bad connections:
- Using Network Link Conditioner - iOS and Mac
- Simulation over WiFi with router firmware
- Simulation by throttling via your network services with custom headers
- Simulation in your app by controlling the flow of data being received
  - Expert mode: drop down to the TCP level!
Timeouts
- List of timeouts:
  - TCP: connection timeout (TLS connection timeout too), SYN timeout, keepalive/idle timeout, retransmission timeout
  - NSURL: request timeout (max time between data being received in response - default is 60 seconds), resource timeout (time for entire transfer to complete - default is 7 days)
  - Custom timeouts: transaction timeouts (time from initiation to completion including redirects and retries), queue timeout (how long can the request be queued without starting before it times), idle timeout (how long can a request do nothing regarding upload or download before timeout)
- NSURLSession has a problem with scale. Every different configuration setting requires another NSURLSession to be maintained and managed. Timeouts, different default headers, different TLS settings, different cookie settings, different NSURLCache, cellular vs non-cellular
Robust API design
- Transactional APIs
- Robust error codes (not just HTTP status codes!)
Retry policies to the rescue

Auto Layout

Stack Views, FTW (Auto Layout without constraints) (New in iOS 9, similar to what’s available in watchOS and NSStackView, which is available from OS X 10.9)
UILayoutGuide
- New in iOS 9
- Defines a rectangular geometry that can interact with Auto Layout
- Eliminates the need (in many cases, at least) for views that are included solely for layout purposes (container views, spacing views, etc)
- Views can still provide a greater degree of encapsulation
- Provide anchors that can be used to generate constraints
Anatomy of constraints
- The layout of your view hierarchy is defined as a series of linear equations. Each constraint represents a single equation. Your goal is to declare a series of equations that has one and only one possible solution.
- Two basic types of attributes
Size attributes (for example, Height and Width)
Location attributes (for example, Leading, Left, and Top)
The following rules apply:
- You cannot constrain a size attribute to a location attribute.
- You cannot assign constant values to location attributes.
- You cannot use a nonidentity multiplier (a value other than 1.0) with location attributes.
- For location attributes, you cannot constrain vertical attributes to horizontal attributes.
- For location attributes, you cannot constrain Leading or Trailing attributes to Left or Right attributes.
Rule of Thumb for clarity
- Whole number multipliers are favored over fractional multipliers.
Positive constants are favored over negative constants.
Wherever possible, views should appear in layout order: leading to trailing, top to bottom.
Constraint Priorities
- 1000 is required
- < 1000 is optional
Intrinsic Content Size
- Content Compression Resistance
- Content Hugging
Debugging Auto Layout
- Error Types
  - Unsatisfiable Layouts. Your layout has no valid solution.
    - Usually 2 or more required constraints conflict
- Ambiguous Layouts. Your layout has two or more possible solutions.
```
  * Need additional constraints
```
  - conflicting optional constraints
- Logical Errors. There is a bug in your layout logic.
Tips and Tricks
- take advantage of the logs
- use meaning identifiers on views and constraints
- Debug > View Debugging > Show Alignment Rectangles

Push Notification Overview

Notifications
- Intended for user
- Certificate required
- Can be disabled
- Remote vs. Local
  - Local - schedule by the app on device
    - Best example is Reminders app
    - Schedule by
      - elapsed time or exact time
      - location based
  - Remote - come from your server
Actions
- Interactive Notifications
- Categories
Text Input
- New type of “Action”
- Behavior is “.textInput”
APNS (Apple Push Notification Service)
- Device token created by APNS, need to store on server, associated with particular client app
- Payload must include aps, but can also include custom values, as well
- Payload “aps dictionary”: alert (string or dictionary), badge, sound, content-available, category
- Payload alert dictionary: title, body, title-loc-key, title-loc-args, action-loc-key, loc-key, loc-args, launch-image
- Silent notifications (content-available == 1) wakes your app in the background so that you can fetch data, etc.
- Feedback service, how to discover tokens that are no longer active
- Device tokens are 32 bytes, may be increasing to 100 bytes soon
- New provider API released in 2015
  - HTTP/2
    - notification requests to APNS get a response
    - multiplexed
    - binary
  - Notification requests
    - POST
    - json
  - Notification responses
    - 200 OK
    - 400 BAD REQUEST with json payload and reason
  - Instant Feedback
    - Allows you to learn about inactive tokens in the notification response via 410 status code in the response
  - Simplified Certificate Handling
    - Now one certificate for all push actions
  - Push notifications payload size increased from 2KB to 4KB

Motivation / Staying Productive

Flow

Mihaly Csikszentmihalyi

Flow theory postulates three conditions that have to be met to achieve a flow state:

One must be involved in an activity with a clear set of goals and progress. This adds direction and structure to the task.
The task at hand must have clear and immediate feedback. This helps the person negotiate any changing demands and allows them to adjust their performance to maintain the flow state.
One must have a good balance between the perceived challenges of the task at hand and their own perceived skills. One must have confidence in one's ability to complete the task at hand.

Clear Distractions

104: Power Struggles

Darryl Thomas & John Sextro — Thu, 10 Mar 2016 09:00:00 GMT

Discussion - Energy Efficiency for iOS Apps

Apple’s Energy Efficiency Guide

Are you telling me I have to worry about my app’s power consumption?

This is iOS. I thought Apple was taking care of that for me...right??

What is Energy?

Power is an instantaneous measurement of energy at any given point in time
Energy is power used over time (Joules measured over watt-hours)
Low power used over a long(er) period of time can amount to the same energy expenditure as short bursts of high power (more on this later)

Major sources of energy consumption/power draw

Device wake
- Aside from being powered off, a device in its sleep state is consuming the lowest amount of energy possible
- Whenever possible, avoid preventing the device from sleeping or forcing it to awaken
- Use technologies like push and background tasks judiciously
CPU Usage
- An idle CPU uses ~10x the power of a sleeping CPU
- Just 1% CPU use costs 10% more than idle
- 10% CPU use costs 200% that of an idle CPU
- 100% CPU can result in 1000% (10x) power draw compared to idle
Networking / Bluetooth
Graphics/animation/video
Sensors
- Location (Wi-Fi/GPS)
- Accelerometer
- Gyroscope
- Magnetometer
Disk IO. Use batch operation whenever possible

Mitigating energy costs

Batching, Batching, Batching
- Operations have a dynamic and fixed energy cost
  - Fixed cost represents the energy used while the device is waiting to enter an idle state
  - The same amount of work, performed across multiple threads, can have a significantly lower total energy cost compared against single-threaded work requiring a longer time to execute
- Network and other inter-device (BT, for example) operations require radios to be powered up. Avoid continuous communications and state polling, batching operations whenever possible
- Defer any operations that aren’t time-sensitive to time that the app will be otherwise active (take advantage of fixed cost you’re already having to pay)
Prioritize operations using Quality of Service Classes (iOS 8+)
- Classes
  - User-interactive
  - User-initiated
  - Utility
  - Background
- Can be set on both NSOperationQueue and individual NSOperation objects
- GCD queues can be created with QOS class attributes
Use timers efficiently, or better yet, avoid them
- GCD provides mechanisms you can use instead of timers, for example dispatch_block_wait()
- If you must use timers (not just NSTimer: basically anything that takes a time interval as a deadline), take advantage of APIs that allow for timer coalescing using tolerances.
Minimize I/O
React to Low Power Mode (iOS 9)
- NSProcessInfoPowerStateDidChangeNotification
- [[NSProcessInfo processInfo] isLowPowerModeEnabled]

Pushing info to clients

Long Polling
- Client sends request to server, waits for response or timeouts (Loop)
- Can send and receive information, but not full-duplex
- iOS Implementation
  - NSURLConnection sendSynchronousRequest
- Common uses
  - Fallback from Websockets and SSE when streams are unreliable or impractical
HTTP Streams
- Can only push information to your client
- If you need to send info back to server use standard rest approach
- Transported over simple HTTP
- Built in support for re-connection and event-id
- iOS Implementation
  - Server Sent Events (SSE)
  - NSURLSession, NSInputStream, NSSteamEvent
  - Setup the connection
  - Implement code to handleEvents from the input stream
- Common uses
  - Stock ticker streaming
  - “Status” feed updating
  - Push Notifications
Websockets
- Designed to overcome many of the pitfalls/shortcomings described in RFC 6202
- Standardized by IETF (Internet Engineering Task Force) in 2011
- Can send and receive information (full-duplex pipe)
- Protocol based on TCP
- Uses HTTP only for initial handshake, while leveraging existing HTTP infrastructure
- iOS Implementation
  - CFStreamCreatePairWithSocketToHost takes url, read and write stream
  - Cast read and write stream to NSInputStream and NSOutputStream, respectively
  - Set delegate for input and output streams
  - Schedule both in a run loop (Can do without but will block the execution of other code)
  - Open connection
  - Write code to handleEvents from the input stream
  - Implement message sending via the output stream
- Server considerations
  - Not as easy to get started with as a generic web server
  - Buy one, borrow one or build one
- Common uses
  - Chat
  - Player vs. Player games
  - Real time interactions
Popular Abstractions/Frameworks
- TRVSEventSource from Travis Jeffery
- SignalR from Microsoft

At-a-glance Comparison

	Websockets	SSE	Long Polling
Client Performance	Best	Best	Worst
Server Performance	Best	Worst	Worst
Complexity	Highest	Lowest	Mid

Discussion

HTTP/1.1 review

Widespread adoption in 1996 with full standard in 1997 RFC 2068 and later replaced with one in 1999 RFC 2616
Request (URL, method, headers, body) & Response (status code, headers, body)
Inherently async
Built for HyperText, makes it have problems
- Head of line blocking
  - combining payloads to 1 response
  - multiple connections (Connection: Keep-Alive vs Close)
  - HTTP Pipelining
- No cancellation, have to tear down connection
- No prioritization, round robin over connections
iOS/Mac
- NSURLRequest (NSHTTPURLRequest) and NSURLResponse (NSHTTPURLResponse)
- NSURLConnection and NSURLSession

HTTP/2

Started by Google with SPDY (2012 - 2016), latest is SPDY/3.1
HTTP/2 is a binary protocol, where 1 and 1.1 are text
Previous episode on SPDY with M Schore
Reached standard in 2015 with RFC 7540 and adopted by Apple with iOS 9, Mac OS X 10.11
Resolves many issues with new features:
- multiplexing (helps with head of line problem in HTTP/1.1)
  - cancellation
  - header compression
    - Always there
    - plain text, optimal for compression
  - dynamic prioritization
be responsible, set lower priority when possible
- not guaranteed that the server will prioritize because it is optional in HTTP/2 spec
- push responses (Nolan’s not a fan)
  - not supported by Apple
Upgrade to HTTP/2 dynamically with Upgrade Header or ALPN
- Application Layer Protocol Negotiation, ALPN is during TLS and far more efficient than Upgrade header
- NPN (Next Protocol Negotiation)

Discussion - iOS App Developers’ Apple New Year’s Wish List

All I want for 2016 is…

The ability to develop apps on the iPad Pro
- Maybe just offer a Swift REPL or Swift Playground
Better Tools
- MSDN offers symbols to subscribers for debugging into Windows OS with Visual Studio, Apple should do the same for iOS and Mac OS X debugging. Let us step through the OS code in Xcode so identifying internal bugs can happen faster.
- Microsoft Symbol Server Info.aspx#using_the_microsoft_symbol_server)
More communication and outreach with the app developer community
- Step 1, Open up the Radar system
- Newsletter / Community Group / Etc.
- App camps for girls
- Groups support and sponsorships
Improve on the App Stores
- Nolan rants about technical underpinning of App Stores and why it will take a top down approach to fix it
- Monetary split
  - Indie devs are struggling. How about giving the devs a larger percentage of the cut, 10/90 (currently 30/70)
  - How about a sliding scale
    - 1 to 10000 (10/90)
    - 10001 to 100000 (20/80)
    - 100001+ (30/70)
- Permit subscriptions and trials
- Trials a far more effective than “Demos” or Free versions. Permit the customer to become attached to a product that when the trial ends they realize they want to pay for it.
- Permit upgrade pricing
  - Devs can’t just support the same version forever, permit them to discount the cost of upgrading from a previous version so they maintain brand loyalty
  - Example: Version 1 was $10, Version 2 comes out and is $10. Having Version 2 be an upgrade from Version 1 for $5 would really be a value to loyal customers.
- Permit devs to address their customers’ concerns/reviews
  - Example 1:
    - Customer: Hey! The app doesn’t install when I download it, what a junk app!
    - Dev: I’m sorry that you aren’t able to install! All installs are managed by Apple and a failure to install usually means there is an issue with the new version of the app propagating through Apple’s CDNs and it will take some time for the CDNs to hydrate properly for the install to work. Here’s an Apple support email address for you to share your concern!
  - Example 2:
    - Customer: Hey! I can’t log in anymore! I hate this app!
    - Dev: I’m sorry to hear that, can you provide me your login name or email and I’ll be happy to look into this for you.
  - Good suggestion. The Google Play Store lets you do this.

Discussion - Core Bluetooth

Bluetooth’s Background
- Invented by Ericsson in 1994 as a wireless alternative to RS-232 serial interfaces
- IEEE 802.15.1 (Bluetooth) part of IEEE 802.15 (Personal Area Network: PAN) within IEEE 802 (Local and Metropolitan Area Networking, LAN & MAN) Wikipedia Link
- The name is a nod to King Harald "Blåtand" Gormsson (Bluetooth is an anglicanized version of "Blåtand"). King Bluetooth is said to have united the Danish tribes into a single kingdom.
- The logo is a bind rune forming the initials H. B. (sort-of)
Versions
- 1.2
  - 1 Mbps data rate, > 80 kbps application throughput
  - Probably the first version considered “viable.”
- 2.0 + EDR
  - 3 Mbps data rate, > 80 kbps application throughput
- 3.0 + HS
  - 24 Mbps data rate, but not really: The connection is negotiated over a BT link, but 802.11 is used for data transfer
- 4.0 (Classic and HS) & 4.0 LE (Branded as Bluetooth Smart)
  - 24 Mbps data rate, but not really: See 3.0 + HS and LE has extremely low throughput by design (like less than 100 kbps)
  - Bluetooth LE
    - Totally new protocol specifically designed for low energy consumption and simplified communications
    - Peripheral devices can implement just LE, just Classic or both
Bluetooth LE and Core Bluetooth
- Core Bluetooth provides a layer of abstraction over the GATT profile (Generic Attribute Profile)
- Peripherals are “servers”
- Centrals are “clients”
- Peripherals serve one or more Service(s)
- Services have Characteristics (can be thought of as attributes or properties)
- Characteristics have a value, which may be readable, writable or notifiable
Using CBCentralManager
- Instantiate the manager and then check for availability (implement the -centralManagerDidUpdateState: delegate method and check for PoweredOn state
- Scan for services with service UUIDs you provide using -scanForPeripheralsWithServices:options:
- When peripherals are discovered, the -centralManager:didDiscoverPeripheral:advertisementData:RSSI: delegate method will be called
Connect to a peripheral using -connectPeripheral:options:, which in turn will call the delegate’s -centralManager:didConnectPeripheral: method.
At this point, you can start using the peripheral directly. (And get responses through the CBPeripheralDelegate protocol)
Discover services with -discoverServices:, which will result in the delegate’s -peripheral:didDiscoverServices: method being called
Similarly, discover characteristics of a service using -discoverCharacteristics:forService:, from which you can expect a -peripheral:didDiscoverCharacteristicsForService:error: message
Depending on the peripheral’s configuration, values for a characteristic can be read, written to or monitored for changes (notified)
Characteristic values are expected to be small. (Like 20 bytes or smaller.) If you need to send larger payloads, it’s possible to roll-your-own streaming protocol atop characteristics.
- I don’t really recommend this, but it’s a fairly common approach
- I suspect some of this comes from the legacy of BT being treated as a dumb serial link
- Apple has recognized this trend and in recent versions of iOS/OS X, they have tried to accommodate higher throughput by negotiating higher MTUs when possible. They even demonstrate how this can be done in one of their WWDC sessions.

Discussion - An Interview with Jaimee Newberry

No Excuses - tiny steps toward huge life changes

After a 15-year, award-winning design career (web & iOS), Jaimee successfully shifted focus from hands-on product creation to coaching and inspiring world-renowned product teams. Through actionable examples, relatable stories, and constant experimentation she helps companies create more compassionate teams and vastly improved digital products. She also coaches individuals experiencing career stagnance or burnout, she writes, speaks, podcasts, YouTubes, and is an independent mom.

Jaimee made this career shift by applying her typical process for designing a product (website or app) to her life, as if her life were the product. (Sometimes she tried Agile methodologies, UX methods, etc.) She started out with smaller objectives and working through side projects to clear obstacles (aka: excuses) from her path. Jaimee continues doing that through her monthly challenges, which have become playful and exploratory things that grow different skill sets and push her own boundaries of fear and comfort.

Discussion: The Hitchhiker’s Guide to Attending Conferences

What conferences do we attend?
Are we attending any upcoming conferences?
Choosing a conference
- Sure WWDC or AltConf, but what else
- Top 10 confs of 2015 from RayWenderlich.com
Why should I go to a conference?
- Inspiration
- Networking
- Jobs
- Emerging technologies
- Training
What type of conference should I attend?
- Structured
- Unconference (Open spaces)
- Vendor controlled
How to get the most from a conference
- Be unique
- Be polite, well mannered and inclusive
- Prepare and practice an elevator pitch (self / project / company / app)
- Be outgoing, but not annoying
- Get outside of your comfort zone (get away from the people you already know)
- Participate
- Identify your ‘must see’ sessions
- If a session isn’t working for you, get out, checkout the “hallway sessions”
Sometimes the best of the conference happens in the hallways
- Make arrangements to stay late
- Some of the best networking happens after the conference
  - Everything in moderation; don’t let one night of overindulgence ruin your conference experience
- When possible, get a room at the venue
- Do you have something to promote? People love free giveaways. Stickers, buttons, pens, etc.
- Find out who else is attending and attempt to make plans with people that you want to meet

Getting the User’s Attention
- Local Notification
Background Data Callbacks
- Bluetooth
- Location Updates
- Newsstand Downloads
- Accessory callbacks
  - WWDC 2014 Session 701 - Designing Accessories for iOS and OS X
Elevated Multitasking Background Work
- VoIP
- Audio / Airplay
  - This is what Facebook has been scrutinized for
Background Processing Work
- [UIApplication backgroundTimeRemaining] - (10 seconds with no background tasks/fetches running)
- Background work is often paired with greatly diminished CPU priority and can often end up with as little as 4% of the CPU
- Background Tasks *[UIApplication beginBackgroundTaskWithName:expirationHandler:]
  - [UIApplication endBackgroundTask:]
  - [UIApplication backgroundTimeRemaining] - (600 secs pre-iOS 7, otherwise 180 secs)
- Background Fetch
  - Project checkbox “Background Fetch” to enable
  - Specify [UIApplication setMinimumBackgroundFetchInterval:]
    - Minimum == as frequently as the OS will permit
    - Never == disable BG fetch callbacks
  - [UIApplication backgroundTimeRemaining] - (~45 secs)
- Push Fetch
  - Effectively the same behavior as background fetch
- Background URL Sessions
  - Download to file or Upload from file
  - Performed out of process
  - Calls back either on completion or when authentication is needed
Remember to clean up when going into the background
- No OpenGL
- Suspend timers
- Expect Network Failures
- Clean up Bonjour and other shared resources (Address Book, Calendar, etc)
- Clear sensitive info from screen
- Clean up alerts (if needed)
- Stop updating UI
- Save the app state
- Clear unneeded resources
- Clean up Audio Sessions (Facebook Bug)

Are you (hosts) testing your apps?
- John’s philosophy on testing
Why should I test?
- When should I test?
- Automated vs. Manual
Problems with the old, Instruments-based UI testing solution
- JavaScript
- JavaScript
- JavaScript
Alternatives prior to Xcode 7
- KIF
- Subliminal
- Quick
- Slepnir
Apple’s new UI testing in Xcode * Requires iOS 9/Mac OS X 10.11
- Test Recording
- Leverages “Accessibility”
- UI Testing Targets
- API components
- Assertions, XCTAssert
Elements, XCUIElement
- Proxy for UI things, exposes object type and accessibility label
  - Queries, XCUIElementQuery
    - Tree navigation, similar to XPath
    - Relationships and Filtering
    - “app.tables” is actually a convenience method for app.descendantsMatchingType(‘table’)
- Application, XCUIApplication
  - Proxy for the application under test, separate and new process
Dealing with Gotchas
- Simulating events
  - No long press, roll your own with pressForDuration
  - No 3d touch press (AFAIK)
- Wait for…
  - using waitForExpectationsWithTimeout
  - without an explicit wait, a total of 3 attempts will be made to resolve a query before failing
- Race conditions
- Item not visible to accessibility
  - Note: “isAccessibilityElement” does NOT need to be true in order to be “visible to accessibility”

Breakpoints

Beyond line-based breakpoints: categorical breakpoints
Types of Breakpoints
- All Exception breakpoint
  Stop on any and all Exceptions.
- Objective-C Exception breakpoint
  Stop on Objective-C Exceptions, eg: NSException.
- Swift Error breakpoint
  Stop on Swift Errors, e.g.: types conforming to ErrorType.
  New in Xcode 7.1 beta 3.
- Test Failure breakpoint
  Stop when a Test fails. XCTest and compatible frameworks only.
- Symbolic Breakpoints
  Stop on a Symbol. A symbol is a selector or method name, or a function name.
  Methods can be scoped to a class.
  eg: pathsMatchingExtensions:
  eg: [SKTLine drawHandlesInView]
  eg: people::Person::name()
  eg: _objc_msgForward
- OpenGL/ES error breakpoints
- Symbolic breakpoints
  - Particularly useful for breaking in private API
  - Also handy for performing debugger setup in UIApplicationMain
    - import UIKit
    - Load/init Reveal library (or chisel, or whatever)
Breakpoint actions
- Play sound
- Execute LLDB command
- AppleScript or Shell Script
- Log Message - %B %H @expr@
Conditions
Options: Continue

  - 1920x1080 - 8,294,400 bytes (~8MB)
- Lossless vs Lossy
- PNG (Portable Network Graphics)
  - lossless (can have alpha)
  - Will be ~3.5MB (naive compression can be poor but tools like PNG Crush can help)
- JPEG (Joint Photographic Experts Group)
  - lossy (no alpha)
  - ~1.1MB at 95% quality and ~650KB at 85% quality
  - Hardware decoding support
    - How Apple quality vs ImageMagick interpreted quality
      - 0.830 == 95%

  - Hardware decoding support
  - ~25% to first scan
- Progressive JPEG–2000
  - Same size as non-progressive
  - 5 different “progressive modes” - again complex
  - Only RPCL and RLCP modes will work with ImageIO on Apple OSes, super fragile too (but it works)
  - ~25% to first full frame
- PVRTC
- Other texture graphics
- SVG (scalable vector graphics)
  - Resolution independent
- GIF (Graphics Interchange Format)

Discussion

What are some nice patterns or not-so-nice anti-patterns/bugs you notice in iOS apps? How can devs go about fixing those problems?

Nolan notices
- Requiring login/signup to use the app
  - My wife’s personal pet-peeve
  - Old Fab.com app vs Zappos app
- Suboptimal table views
  - Stuttering
    - Get off the main thread: includes networking and UIImage rendering
  - Content flashing in once it scrolls into view
    - Prefetch content before it comes on screen: can be easy with table view buffering
- Requesting all permissions on first app launch with no context!
  - On demand prompting
  - Interstitial
    - Even better: don’t indicate they will be prompted, rather outline the feature and why it needs the permissions and have the user explicitly ask to grant permissions (Periscope does something like this )
  - Example: (User selects post a photo) Prompt says something like: “A picture is worth a thousand words. We’d like for you to be able to share any of you iPhone’s photos. By enabling us to access your photo library, you can choose from photos you already have to share with friends and family.” Below is a empty checkmark with text “Enable access to photo library” and below that is a “Close” button. Hitting the checkmark will ask for access and user knows exactly why they were prompted. Hitting close will save the setting as “on” or “off” based on if the checkmark was successfully checked.
Chad notices
- Social login (FB/Twitter) only to ask for username/password/email afterward anyway
- Bad pull-to-refresh implementations (Apple, Twitter)
Darryl notices
- Lack of accessibility
- Not conforming to the design language of the platform (Note that I didn’t say HIG)
- Re-inventing system-provided controls/mechanisms for the provider’s gain, not the user’s
- Facebook/Twitter/SocialMediaX sign-in as the only option
- Crappy validation. Example: + is perfectly legal in email addresses
- Collecting address book information to build a social graph

Discussion - UIStackView

Referred to by Apple as “your first stop for interfaces built with Auto Layout” in the description of WWDC15 Session 218
Manages the constraints of a vertical or horizontal linear layout
Easy migration of IB-based layouts using the new “Embed in Stack View” button
Subviews that are to be managed by the stack view are added to the arrangedSubviews property. This allows decorative views to be added directly to subviews without affecting the arrangement.
- Potential pitfall: Removing a view from the arrangedSubviews array does not remove it as a subview. The stack view no longer manages the view’s size and position, but the view is still part of the view hierarchy, and will be rendered on screen if it is visible.
Multiple distribution styles
- UIStackViewDistributionFill - A layout where the stack view resizes its arranged views so that they fill the available space along the stack view’s axis. When the arranged views do not fit within the stack view, it shrinks the views according to their compression resistance priority. If the arranged views do not fill the stack view, it stretches the views according to their hugging priority.
- UIStackViewDistributionFillEqually - A layout where the stack view resizes its arranged views so that they fill the available space along the stack view’s axis. The views are resized so that they are all the same size along the stack view’s axis.
- UIStackViewDistributionFillProportionally - A layout where the stack view resizes its arranged views so that they fill the available space along the stack view’s axis. Views are resized proportionally based on their intrinsic content size along the stack view’s axis.
- UIStackViewDistributionEqualSpacing - A layout where the stack view positions its arranged views so that they fill the available space along the stack view’s axis. When the arranged views do not fill the stack view, it pads the spacing between the views evenly. If the arranged views do not fit within the stack view, it shrinks the views according to their compression resistance priority.
- UIStackViewDistributionEqualCentering - A layout that attempts to position the arranged views so that they have an equal center-to-center spacing along the stack view’s axis, while maintaining the spacing property’s distance between views. If the arranged views do not fit within the stack view, it shrinks the spacing until it reaches the minimum spacing defined by its spacing property. If the views still do not fit, the stack view shrinks the arranged views according to their compression resistance priority.

Programmer vs. Developer vs. Engineer discussion
- Re: Episode 76
- Episode 76 had a great topic that was really thought provoking regarding Programmer vs Developer vs Engineer.
- Everyone can probably has an opinion on what those titles mean
- Fascinating: we’re inclined to rank things
- Their all title for someone who makes software or code
- Maybe “Software Producer” or “Talent” is less biased
- Code Poet is my favorite (thx John)
Alternate views
- Instead, I like to examine the skills
- Instead of Programmer vs Developer vs Engineer; look at Programming, Development and Engineering as buckets of skills
Full-time Equivalent

The 5 skills

Hacking * bringing together a system of potentially disparate computer apps/tools/functions to achieve a goal * Gluing together anything you can get your hands on to build a workflow or solution takes talent and skill * Often the goal of Hacking is really “discovery” or “exploration”
Movie Reference: Hackers
Programming
- writing code/scripts to pull together potentially disparate functionality and/or frameworks to achieve a goal
- You create a whole that is more valuable than the sum of its parts
- amassing and consuming huge amounts of knowledge about APIs and Frameworks that are available and then using them effectively
Development
- the process of bringing together talent, ideas and requirements to build a new application or feature
- Deals with other people and takes input from all over to build something new
- it’s inherently collaborative and requires other skills like interpersonal skills and communications skills
- often called soft skills which I find ironic because it’s so hard
Engineering
- the use of science and creativity to solve complex problems
- It needs an academic foundation combined with creativity and ingenuity to solve hard problems
- These skills get amplified in value when complemented by others who can fill in any knowledge or skill gaps
Architecture
- the design of a large complex system or application that requires numerous contributors to fully implement
- it is a skillset that can envision, design, and clearly document and communicate a complex system in a cogent way that everyone tasked with implementing the system are able to apply their skills to succeed with little or no impediment?

Swift

Follow-up/Corrections
2 episodes ago, Darryl mistakenly referred to Swift 1.3 beta. He meant to say 1.2 beta.
- Tuples
  - Contents can be decomposed in a manner very similar to the decomposition of an enum value’s associated values
  - Elements can be accessed using dot notation with its zero-based index.
- Particularly useful as the return value of functions
  - Group values into a single compound value.
  - Values need not be of the same type
  - Multiple ways of getting at the composed values
    - “_” can be used to ignore parts of a tuple.
  - Elements of a tuple can be named, and subsequently accessed by name using dot syntax.
  - If the data structure is likely to persist beyond a temporary scope, consider a class or structure instead.
Functions
- syntax
- parameters
  - local vs. external parameter names
  - variadic
  - in-out
  - default parameter values
- return
  - multiple return values
  - option tuple return types
  - void defined as empty tuple ()
- function types
  - syntax
  - as parameters
  - as return types
Closures
- terseness
- Types
  - Global Functions
  - Nested Functions
  - Closure Expressions
- Trailing Closures

Data
- value types
  - enums
    - can have initializers, can be extended and can conform to protocols
    - Swift enums do NOT get default integer values

    - No ref counting, since value type
- reference types
  - classes
    - very similar to structs (but ref type)
    - inheritance
    - Ref count for memory management
- Swift Diff: dot syntax allows us to directly set sub-properties without intermediate assignment (reduces instance creation and malloc)

Continuous Delivery Challenges in Mobile Development

CD (Continuous Deliver) is well accepted and understood in web development.
- What is the view of CD in iOS development?
- Is the review process “barrier” just too long and uncertain to make it viable?
- At what frequency do app updates become bothersome to users?
  - Is Apple trying to help solve this with the “Autoupdate” capability?
- If CD doesn’t work for Prod releases is it worth setting up for “user acceptance testing” purposes?
- Tool support?

SceneKit

For a discussion of Apple’s Metal Framework, see Episode 44

@iOhYesPodcast Hello from Romania, Europe! Very nice podcast:) If you accept topic suggestions I would like to hear about SpriteKit/SceneKit — Ilea Cristian (@ileacristian) October 22, 2014

Here you go, Ilea, this one’s for you…

What is SceneKit?
- Objective-C framework for building apps and games that use 3D graphics
- High-performance rendering engine
- High-level, descriptive API
- Supports animation based on the Core Animation framework with defined animatable properties
- Abstracts away the rendering algorithms used to display a scene, meaning you don’t need to worry about things like:
  - Object ordering
  - Culling
  - Shaders (though you can write your own if you like)
What is SceneKit not?
- A game engine (you must provide your own logic)
- An escape from linear algebra
- Cross-platform (but who wants to support Android anyway?)
- A fully-featured substitute for solutions like Unity3D
Why use SceneKit?
- Very easy way to get your feet wet with 3D graphics
- Suitable for simple games
- Rapid implementation of visualization apps
Major features
- Available on Mac OS X and iOS
- Integrated inspection (model viewer, material editor, particle editor) and debugging in Xcode
- COLLADA importing
- Supports geometries, materials, lights and cameras
- Animatable properties
- LoD substitution (level-of-detail, allowing for variable geometry complexity)
- Actions (allows for animation triggers, sound effects, etc)
- Skinning and Deformations
- Static/dynamic shadowing
- Physics, including joints and inverse kinematics
- Particles
- Ray casting/hit testing
- Custom OpenGL shader programs
- JavaScriptCore bridging
- SpriteKit overlays for performant 2D UI elements that don’t require an additional compositing pass
The basics (iOS-specific)
- Assets are contained within a Scene Assets container in your Xcode project
- Xcode performs optimizations at build-time (up-axis correction, vertex interleaving, PVRTC image format favoring, etc)
- Scenes can be imported from COLLADA (in Xcode. The dae file is converted to a bplist [retaining the .dae extension] before it is put on the device) or un-archived from plists.
- Scenes consist of a graph of nodes.
  - Root node: defines the world’s coordinate space
  - sub-Nodes: populate the world with visible content by attaching:
    - Cameras
    - Lights
    - Geometries
- Scenes can be built-up (or modified after load) programmatically.
- sub-Nodes from other scenes can be added to a scene, but a root node must not be added to another scene.
- Important classes
  - SCNView - a view that displays SceneKit content
  - SCNScene - The container for all SceneKit content
  - SCNNode - The basic building block of a scene
  - SCNGeometry - A three-dimensional object that can be attached to a node. Also known as a mesh or model. SceneKit has several built-in primitives that can be used, or custom meshes can be imported or built from vertex data. Surface appearance is defined by materials attached to the geometry.
  - SCNMaterial - A reusable definition of surface appearance properties for an object
  - SCNLight - A light source that can be attached to a node, providing shading in the rendered scene
  - SCNCamera - A virtual camera that can be attached to a node, providing a point of view for rendering a scene.

The Discussion

The Open-Office Trap published in the New Yorker, by Maria Konnikova
- 1997 - The University of Calgary study (before, 4 weeks after and 6 months after)
  - Disruptive, stressful, cumbersome, dissatisfied, resentful
  - Productivity fell
- 2005 Study
  - When workers couldn’t change the way that things looked, adjust the lighting and temperature, or choose how to conduct meetings, spirits plummeted.
- johnsextro This article sounds like a bunch of crying from a pretentious primadonna http://t.co/x3jDzAerwC
- Types of open floor plans
  - the blank slate - just tables and chairs
  - moveable walls - rolling or sliding walls/whiteboards used to create separation
  - Team Area / Pit / Bullpen - semi-private partitions, not easily reconfigured
John’s opinions
- Cubicles, they suck
  - False sense of privacy
  - They don’t contain nor block noise
  - They get in the way and are a waste of space
- Offices, slight better but still bad
  - They can contain and block noise
  - But they are a terribly inefficient use of space
  - Stifling to collaboration and fascist
Darryl’s opinions (read: facts)
- Open floor plans, they suck
  - Amusing article (http://verynicewebsite.net/2015/01/be-yourself-as-long-as-its-your-best-self/)
  - Workers are left with no sense of personal space as a company grows
  - The universally proposed “solution” to noise is headphones, read: OTHER NOISE
  - People feel free to interrupt your workflow in person, as if IM and email wasn’t bad enough
  - Note: I think this actually works well for teams up to 10 quiet people (no phone calls, etc), beyond that, it’s untenable
  - My favored compromise solution: Bullpen cubes (cubes that can accommodate teams of 4-5 people)
- Cubicles, I hated them until I no longer had them
  - I miss my partitions
  - Cubes actually do affect noise levels: they discourage yelling across the room and deflect and diffuse/absorb audio a bit (when built properly)
- Shared offices, I love ‘em
  - Office with up to 3 occupants
  - Can get cramped, but with good office-mates, it’s pretty harmonious
  - Especially good if your office mate is always going to meetings (and you aren’t)

The Discussion

WatchKit / Pebble
- WatchKit design decisions: code runs in the phone, not on the watch. API is synchronous, but with no getters.
- The big success of WatchKit is making the API transport-agnostic: no mention of Bluetooth.
  - It may even use Ad-Hoc Wifi to send larger amounts of data.
- General confusion around the limitations of WatchKit:
  - It’s NOT the API to make watch apps, but a way to extend iOS apps by “projecting” data to the watch.
  - Native apps coming later.
- A win of making watch apps extensions is that, at least for now, the user doesn’t need to manage which apps you install on the watch, eliminating one of the frictions of the Pebble.
  - Another consequence is it eliminates the need to log into apps separately for the watch, like you have to do with Pebble apps.
  - Apple needs to get App Store discovery right.
- beta 2 released today (Dec. 10); API changes in 8.2b2
  - [WKInterfaceController +openParentApplication:reply:]
  - [UIApplicationDelegate -application:handleWatchKitExtensionRequest:reply:]
    - From the docs: “A dictionary containing data to return to the WatchKit app. The contents of the dictionary must be serializable to a property list file. The contents of this dictionary are at your discretion and you may specify nil.” (emphasis our own)
  - Default row appearance in WKInterfaceTable, which can be overridden by specifying bg color, margin, corner radius and height in IB
  - Blog post by _DavidSmith

Darryl’s opinion:

Article on the “Threes ripped off by 1024, which is in turn ripped off by 2048” “controversy”: 2048’s Massive Popularity Triggers Cloning Controversy - Kotaku
At what point does a game define a new genre, which makes cloning inevitable? If game mechanics vary slightly, is that enough of a distinction? (I think so, but there are many who would consider the game mechanics to be every bit as much of the “art” as the game’s content.)

Jason's opinion:

The market usually doesn’t care about fairness. Being an indie developer means running a business. Businesses must always be evolving to “put themselves out of business” or else your competitors or copycats will.

Metal - Low-overhead GPU access for iOS 8
- What is Metal?
  - Modern, Thin API for GPU programming (graphics and simd compute)
  - Designed for A7 and newer SoCs (iPhone 5S and newer)
  - Shader/kernel language based on C++11
- Who should/will use Metal?
  - In-house/roll-your-own 3D engines/frameworks
    - For most folks, using Metal or OpenGL directly is overkill (but fun!)
    - Alternative, higher-level APIs include SceneKit (3D) and SpriteKit (2D), which provide much more than just graphics rendering support, including graph management
  - Third-party 3D engines/frameworks
  - Compute-heavy applications and filters with highly parallelizable work
    - DSP
    - Image filters
    - Protein folding?
    - Note: Swift currently doesn’t support importing C unions or SIMD vector types. Chris Lattner acknowledged this, citing feature prioritization (so it’s reasonable to be hopeful it’s coming in the not-so-distant future). In the meantime, if you need to work with SIMD, you may want to stick with Objective-C when using Metal.
- Practical differences between Metal and OpenGL ES
  - In Metal, command buffers are exposed, giving control over when the commands are sent to the GPU to the application and putting the onus of asynchronous framing on the application
  - Most state is stored in immutable state objects that are created at setup, not in each draw cycle, allowing for quick state change that doesn’t require expensive recompilation of shaders/validation
  - Streamlined API. OpenGL provides many ways to do (effectively) the same task largely due to its evolution. Metal sheds many of the legacy techniques.
  - Metal provides direct access to the A7’s shared memory. Thread safety/synchronization is the responsibility of the app.

  - 401ppi @ 1920x1080
  - Apps that have not been updated for adaptive layout are scaled up
- Dual domain pixels - accurate colors at wider angles of view
- Plus has 185% more pixels than 5s
  - Does the Plus have the GPU horsepower to drive this, or are we in the same situation as the first Retina iPad?
  - We’re probably in good shape: the 5s has oodles of GPU to spare, and the A8 has up to 50% greater performance, according to Apple.
  - Screen not all that different from an iPad Air, which had an A7 in it
  - Relevant: http://www.anandtech.com/show/8514/analyzing-apples-a8-soc-gx6650-more
- Very thin, but at the cost of a protruding camera. They both have a bump?
- What do you get with a ridiculously large phone?
  - Need a pair of JNCO Jeans to fit the 6 Plus in your pocket
  - Plus leverages adaptive layout to provide "regular" size-class content when in landscape. (Referred to as 2-up in the keynote)
  - Expanded keyboard in landscape: Cut, copy, paste, etc
  - Springboard supports landscape
  - Sleep/wake button moves to the side
  - Reachability slides the top of the screen down so you can reach it.
    - Is this a necessary concession of ridiculous phone size?
    - Will we see the iPad adopt this?
- A8 SoC
  - 2 billion transistors (up from 1 billion)
  - 20-nanometer process
  - 13% smaller than A7

  - Pretty significant improvements. Too many to enumerate
  - Plus supports optical image stabilization
Apple Pay
- $12B/year in cc/debit transactions in the U.S.
- Contrived video showing how difficult using a card is
  - She even fumbled while removing her card from its sleeve
  - Is paying with a card really so inconvenient
- Followed by a video showing how easy Apple Pay is
- “Secure Element” chip stores device-specific payment info on the device
  - Credit card number is not stored
- Single-use payment numbers and dynamic security codes for each transaction!
  - Darryl has wanted this to be the standard for quite a while (Tweets from 2011)
- Apple does not collect transaction details
- Developer APIs available via PassKit (Getting started with Apple Pay PDF)
- Nick Arnott (@noir): 9/10/14, 7:11 AM 220,000 locations sounds like a lot until you realize that’s out of roughly 14.26 million credit card terminals in the US. Long way to go.

- “Glances” mini-widgets
- LOLling at the zoomed-out photo collection view
- Was Yo on to something? Apple seems to think so, given their “communicate with taps” feature

The Discussion

Extensions
- What are they
  - Turns out..."Extensions" is not a single concept. Multiple flavors known as extension points.
  - App Extension lets you extend custom functionality and content beyond your app and make it available to users while they’re using other apps.
  - App Extensions are a separate binary that runs independent of your app.
- Extensions Points
  - Today - interact with the “Today” view of notification center
  - Share - Post to sharing website (twitter) or share content with others
  - Action - manipulate or view content within the context of another app
  - Photo Editing - edit a photo with Photos app
  - Finder (OS X only) won’t discuss
  - Document Provider - manager files
  - Custom Keyboard - replace custom keyboard
    - Apple is really stressing “Trust” as a key when creating a custom keyboard. Your users are giving you access to everything they type including passwords and other sensitive data.
- App extension must exactly match one of the types of extensions. You can’t create a generic extension that matches more than one extension points.
- What can’t they do
  - Access a sharedApplication object
  - Use any API marked in header files with the NS_EXTENSION_UNAVAILABLE macro
  - Access camera or mic
  - Perform background tasks
  - Receive data via AirDrop
- Distribution
  - App Extensions must be delivered via a Containing App on iOS.
- Common Needs
  - Sharing data with containing app requires special considerations. Need to use a share container. Watch out for data corruption/
  - Deploying to older version of iOS
    - Need to take advantage of conditional linking
    - Use dlopen command if systemVersion return iOS 8.0 or later

The Discussion

“On the feasibility of Large Scale Infections of iOS Devices”
- 2 Security Issues
  - the iTunes syncing process is vulnerable to Man-in-the-Middle (MitM) attacks
  - an iOS device can be stealthily provisioned for development through USB connections. This weakness allows a compromised computer to arbitrarily remove installed third-party apps from connected iOS devices and install any app signed by attackers in possession of enterprise or individual developer licenses issued by Apple.
CloudKit
- Cost model - https://developer.apple.com/icloud/documentation/cloudkit-storage/
  - Any hard numbers yet?
- vs. Parse
  - Parse supports JS, Android, Java, etc.
  - Cloudkit - iOS 8+ / OS X 10.10+ devices
  - CKRecord == PFObject, CKQuery == PFQuery, CKAsset == PFFile?
  - What’s the difference in pricing?
  - CK doesn’t have any server-side capabilities (just data storage + pub/sub on changes)
    - This seems like potential tech-debt
- CKDiscoverAllContactsOperation
  - https://developer.apple.com/library/prerelease/ios/documentation/CloudKit/Reference/CKDiscoverAllContactsOperation_class/index.html#//apple_ref/occ/cl/CKDiscoverAllContactsOperation
  - “The search of the user’s address book does not return any personal data about the user’s contacts. The search returns only the IDs of the corresponding user records, which contain only data that your app puts there.”
  - Requires user permission

Mobile Accessibility - getting into the details

iOhYes Podcast Episode 35 - Includes a discussion with Neem Serra about the importance of making apps accessible

The basics

UIAccessibility protocol reference

Advanced APIs

UIAcessibilityContainer protocol reference

UIAccessibilityAction protocol reference

UIAccessibilityPostNotification() reference

Thoughts on accessible design

What considerations should be made in terms of information density?
How do we maintain accessibility as design trends toward gesture-driven UI?
How does one strike a balance between avoiding too many user preferences and providing adaptability for special needs?

Riemann Sum: UIAccessibility Demo - Sommer Panage on GitHub

The application allows the user to model one of 3 functions in a graph and select the number of rects to approximate the integral using a Riemann Sum. (This demo uses the Left Riemann Sum.)

This app has been made fully accessible to demonstrate the use of Apple's UIAccessibility protocols / classes. It demonstrates basic accessibility additions via customization of accessibilityLabel properties thru more advanced accessibility via custom accessibility containers.

    https://twitter.com/chockenberry/status/487281074863497217
    @gruber As making a profit with apps gets harder every day, doing the extra accessibilty work is the first thing to get chopped.
    https://twitter.com/chockenberry/status/487281329323528194
    @gruber Apple CAN do something about making it profitable to implement accessibilty. Surprising that there's no App Store section for it…

  - Why is this different from making applications on computers accessible? Is it different?
  - Are there apps that should be required to be “accessible”?
    - Should Apple enforce accessibility for these apps?

SPDY overview, http://www.chromium.org/spdy/
Why is SPDY important to mobile / iOS developers?
1. Why not just straight HTTP?
  1. TCP “Slow Start” helps protect the network, but isn’t really necessary anymore and is a shortcoming of HTTP today.
2. Reduce round trips
3. Multiplexes requests
  1. prioritization
  2. interleaving
  3. gets rid of “head of line” blocking
4. Header compression
  1. headers are bloated and redundant
5. Server Push (pseudo duplexing)
CocoaSPDY https://github.com/twitter/CocoaSPDY
1. How does one integrate it into existing apps?
2. Any gotchas?
  1. CRIME Attack
  2. Content hinting by size of the compression
3. Downsides?
  1. Need a server that supports SPDY
    1. netty
    2. jetty
    3. apache (with mod_spdy)
    4. nginx
    5. Tengine
4. Any improvements / new features on the way?
  1. “Server Push” coming soon
5. In theory...works with AFNetworking
6. How can developers contribute?
  1. Github https://github.com/twitter/CocoaSPDY
  2. @goaway
Recommended server implementations?
“SPDY does not clearly outperform HTTP over cellular networks” - http://conferences.sigcomm.org/co-next/2013/program/p303.pdf
1. Heterogeneous nature of mobile networks makes it difficult to quantify performance

Worm in the Apple, Apple TLS bug - Discussion of what this means to support of iOS 6.
1. Actual Source
2. What is it? Description of bug, Deep Dive Description
  1. “Note the two goto fail lines in a row. The first one is correctly bound to the if statement but the second, despite the indentation, isn't conditional at all. The code will always jump to the end from that second goto, err will contain a successful value because the SHA1 update operation was successful and so the signature verification will never fail.”
  2. Lack of curly braces on single line conditional to blame, or lack of testing the code?
3. What does it mean for users?
4. How could this have happened and gone undiscovered for so long?
Background User Input recording discovered - Reported Monday night. Ars Article
1. Can you actually infer keyboard touch events?
