For those wondering about the NDA, we tend to agree with Ray Wenderlich and Craig Hockenberry, that “Since the Apple Watch SDK docs are open to the public and we haven’t heard anything to the contrary, we are assuming it is OK to talk about WatchKit at this point. If anyone hears an official word on the matter, please let us know!” — Greg Heo on raywenderlich.com

At the 2014 August CocoaHeads meetup in Sydney we were verty fortunate to have Manuel Chakravarty give us a talk titled “Swift—Adopting functional programming”. Manuel is an internationally renowned expert on functional programming based here in Sydney. Manuel is this year’s program chair of ICFP (The International Conference on Functional Programming), but he took time to talk to just a few days before flying out.

Apple’s new language Swift supports functional programming while being tightly integrated with Objective-C and Cocoa. This has sent the developer community on an adventure to explore how ideas from functional programming might help writing great apps for iOS and OS X. In this talk, I will concentrate on two of these ideas: types and immutable data structures. How do they benefit development, and how do they affect code architecture?

In addition to the video (which includes the slides) you can find just Manuel’s slides on SpeakerDeck.

CocoaHeads new injection Lawrence Lomax not only has the third best name after Max Power and Scott Speed, he gave a great talk titled “Super! Awesome! Functional! Reactive! with ReactiveCocoa!”. Apparently it’s something to do with cats.

Craig Stanford walks us through the basics of layer masking – using a monochromatic CALayer as as content mask for another CALayer.
