Reusing build phase for multiple targets in Xcode

noemail@noemail.org (Iiro Alhonen) — Tue, 4 Oct 2022 10:24:19 GMT

Can I reuse the same build phase for multiple targets?

I have multiple targets on my project and I want to run SwiftLint for all the targets as a build phase.

Is there a way I can achieve this without duplicating the build phase?

Xcode 13+ Missing "Products" folder when creating a framework

noemail@noemail.org (Moos) — Sat, 8 Jan 2022 18:52:16 GMT

In Xcode 13+ When I create a framework, there is no "Products" folder as it used to be there prior to that version same like the below image

Even when I build the project, I still cannot find the ".framework" file anywhere. All tutorials on google follow the same flow of creating the framework project, building then extracting the .framework binary from the Products folder, but that doesn't seem to be available in Xcode 13+ Any one have a clue?

Apple Watch can't always reconnect

noemail@noemail.org (Ирина Пересыпкина) — Tue, 21 May 2024 12:43:54 GMT

Using Xcode to build and deploy the app to my watch, this is what I get:

“Waiting to reconnect to Apple Watch. Previous preparation error: Transport error." And then “Connecting to Apple Watch. Xcode will continue when the operation completes.” And these messages continue to switch between each other.

Sometimes the watch to connect and the application starts, but more often a scenario occurs with endless reconnection.

I'm using: MacOS 14.4.1 (MacBook Pro 2019; 1.4 GHz Quad-Core Intel Core i5), Xcode 15.3, Watch OS 10.2 (Apple Watch SE 1), iOS 17.1.1 (iPhone 15 Pro).

Any help?

Methods I tried: Connecting Macbook, iPhone and Watch to the same WIfi network; Disabling Watch (and IPhone) from the "Devices and Simulators" menu and setting up Watch (and IPhone) from the beginning.

Where should I put the .gitignore file in my xcode project? [duplicate]

noemail@noemail.org (Mauricio Alberto Barragn Huert) — Mon, 12 Mar 2012 18:01:06 GMT

I want Git to ignore my UserInterfaceState.xcuserstate file in my XCode4 project, but where should I put the .gitignore file? Is it inside the .git folder or outside?

The .git folder is in same folder with the ProjectName.xcodeproj file.

How do I use an SF Symbol in Swift using its symbol literal instead of its name?

noemail@noemail.org (Senseful) — Thu, 14 Jul 2022 11:50:38 GMT

The normal way to use an SF Symbol is to find the image you want in the SF Symbols app, copy its name, and then use this name in the Image(systemName:) constructor. For example, if I'd like to display the share Icon, I could use the following code:

Image(systemName: "square.and.arrow.up")

This will produce the following image in the UI:

This is great, but just like color and image literals, I was hoping that instead of the string square.and.arrow.up I could have something more literal in my code. For example, if I choose "Copy symbol" in SF Symbols and then paste that into Xcode, I get a string which represents a "symbol literal":

If I try using that code, though, I get the following error:

No symbol named '􀈂' found in system symbol set

Is there another way to use this Symbol within Xcode and have it provide me an Image with the corresponding systemName so I can stop using the string square.and.arrow.up in my codebase and instead use the symbol literal?

My current workaround is to add the literal symbol as a comment, but I'd like to avoid duplicating the symbol:

Other things I've tried:

Image(_ name:bundle:): This doesn't show anything.
Text(_ content:): This shows a black square with a question mark.
Using an #imageLiteral: I investigated this a while ago but couldn't find a way to do this.

Xcode Preview crash with ModelContainer initialization

noemail@noemail.org (Tony Chen) — Wed, 24 Dec 2025 16:54:31 GMT

Background:

I have complex Swift Data models with some Relationships, and at some point, my Xcode Preview is no longer working when I want to init a ModelContainer in it. So I tried to debug and create a simple file with no dependencies with other parts of my project.

Here's my simple code:

import Foundation
import SwiftUI
import SwiftData

struct DebugView: View {
    var body: some View {
        Text("Hello")
    }
}

@Model
class User {
    var name: String

    init(name: String) {
        self.name = name
    }
}

#Preview {
    let config = ModelConfiguration(UUID().uuidString, isStoredInMemoryOnly: true)
    let container = try! ModelContainer(for: User.self, configurations: config) // This line failed
    DebugView()
}

The thing is even this simple view cannot be shown in the Preview window. Error message:

I'm sure that the crash line is at the ModelContainer init because it works fine without it.

I tried to delete the cache data with command:

xcrun simctl --set previews delete all

But it's still not working.

The weird thing is, when I created a new project and move all the files in it, it works at the beginning. But it started to failed when I tried to do some modifications on other files (these simple codes stay unchanged).

Does any one have any idea?

pod install Xcode Error Failed to save foo.xcodeproj

noemail@noemail.org (make) — Tue, 18 Jun 2024 08:39:16 GMT

I've been encountering an issue where, after running pod install, Xcode consistently throws an error: "Failed to save foo.xcodeproj." To clear this warning, I have to click through it more than 50 times.

This has become quite frustrating, as it happens every time I run pod install. Is there a way to prevent this error from occurring?

Kotlin Multiplatform Mobile unable to run on iOS: Execution failed for task ':shared:compileKotlinIosX64'

noemail@noemail.org (Fatin Wasta) — Tue, 9 Feb 2021 05:24:18 GMT

I have created fresh project(Hello World) in KMM followed by their official website. In android it works smooth but when I am trying to run in XCode it's giving errors because of which I am unable to build / run the xcode project. I have attached screenshots and logs for my errors.

Can't rearrange files in Project Navigator

noemail@noemail.org (adamek) — Sun, 4 Aug 2024 06:44:08 GMT

I created a new workspace. I added several files and folder to it. Now I can’t rearrange the files within the groups. Files in the Project Navigator are only showing up in strict alphabetical order in each group.

This problem is not showing up in other older workspaces.

The problem does show up in another new workspace I just created.

Does anyone know a setting in Xcode that could be causing this?

It could be a beta problem. I'm using Version 16.0 beta 4 (16A5211f). I have filed feedback with Apple.

StoreKit 2 Sandbox: transaction.finish() logs requestEncodeFailed and replays subscription renewals on every launch

noemail@noemail.org (Fran) — Fri, 14 Aug 2026 01:00:52 GMT

I’m testing an auto-renewable subscription using StoreKit 2 on a physical iOS device with a Sandbox account.

A fresh purchase succeeds, Transaction.currentEntitlements contains an active transaction, and the app unlocks the subscription correctly.

The app starts a single Transaction.updates listener at launch and finishes every verified transaction:

Task {
    for await result in Transaction.updates {        
guard case .verified(let transaction) = result else {
            continue        
}
        // Deliver/reconcile the entitlement first.
        await transaction.finish()
    }
}

However, every call to finish() produces this internal StoreKit console error:

Error finishing transaction:StoreKitServiceError(
    error: StoreKitInternalError.requestEncodeFailed,
    environment: Sandbox
)

On every subsequent launch, Transaction.updates delivers the same original purchase and all of its renewal transactions again. Calling finish() again produces the same error.

The subscription remains active and currentEntitlements is correct while its expiration date is in the future.

After the Sandbox subscription eventually expires, product.purchase() may return .success(.verified(transaction)) with one of those old expired transactions without presenting the system purchase confirmation sheet. currentEntitlements is then empty, so the app correctly does not unlock the subscription, but the user cannot initiate a new purchase.

The same implementation works correctly with an Xcode StoreKit configuration:
purchase → expiration → repurchase presents the confirmation sheet and succeeds.

Transaction.finish() is nonthrowing, so the application cannot detect or retry requestEncodeFailed as a Swift error.

How can I avoid this issue?

How do you show a NSStatusBar item AND hide the dock icon?

noemail@noemail.org (xtian) — Mon, 24 Jul 2017 23:18:07 GMT

I've tried setting "Application is Agent" to 1 but the status bar item disappears. When set to 0 both the status bar item and dock icon are showing. How do I show the status bar item but hide the dock icon?

I've tried the following in both awakeFromNib() and applicationDidFinishLaunching() in AppDelegate.swift:

//class scope    
let statusItem = NSStatusBar.system().statusItem(withLength: NSVariableStatusItemLength)

//function scope    
self.statusItem.image = NSImage(named: "myImage")
let menu = NSMenu(title: "MyApp-Menu")
let menuItem = NSMenuItem(title: "title", action: nil, keyEquivalent: "")
menu.addItem(menuItem)
self.statusItem.menu = menu

Black screen my app on Simulator and stuck at Launching App every couple of runs - macos ventura

noemail@noemail.org (MBH) — Sun, 23 Apr 2023 18:15:36 GMT

While developing native apps from Xcode, the screen of my app goes black and Xcode is stuck on launching app and attaching to iPhone 14 Pro as in screenshot below:

When my app's screen goes black, the simulator still works normally. If I kill my app and restart it, it stuck on launch screen.

I tried before last updates to set to Rosetta Stone, but I was facing same issue. After updating Xcode and macOS, I don't even have the Rosetta option.

I am using:

Device: Macbook Pro, M1 Pro
Xcode: 14.3 (14E222b)
macOS: Ventura 13.3.1
project is developed with Swift, uses Cocoapods

The only thing that works now is killing the process of the simulator completely, and restarting it from Xcode.

NOTE: When I develop flutter apps from Android studio on iOS Simulator, everything works just fine.

UPDATE: 09/19/2023: It is still the same on Xcode 15.0 public release.

How to stop Xcode from automatically adding close quotes, parentheses, and braces when typing in a plain text file?

noemail@noemail.org (HangarRash) — Fri, 19 May 2023 05:17:56 GMT

I have a plain text file in my Xcode project I use to make notes as I work.

One really annoying "feature" of Xcode is its insistence on adding a matching ', ", }, or ) if I type a ', ", {, or ( respectively, followed by another character.

For example, if I simply want to type the word it's, then after I've entered the it', as soon as I type the s, Xcode automatically adds a "closing apostrophe" and I end up with it's'. And when I don't notice and continue typing, I end up with something like it's an annoying feature' (note the extraneous ' at the end).

How can I turn off this feature, at least for plain text files?

I've been through all of the settings and I've looked through the Editor menu but I can't see anything relevant.

The only thing I've found is in the key bindings there is a binding for Ctrl-' (^') mapped to "Insert Single Quote without Extra Action (Insertions and Indentations)". But this doesn't seem to apply in my example. If I type it, then Ctrl-', then s, I still get the extraneous ' at the end.

Navigation bar back button “jumps” on first push from TabBar root on iOS 26 Beta

noemail@noemail.org (Paulo Silva) — Mon, 1 Sep 2025 09:48:06 GMT

Short description / problem

When I push from a tab bar root navigation controller to a new screen, the navigation bar back button jumps (moves out of place) briefly during the push animation and then snaps back. This is consistent for the first push from the tab root. If I push deeper (increase stack depth) the jump does not happen. This does not occur on iOS 18. Console shows no warnings that are consistent enough to detect any patterns.

It seems like a conflict with iOS 26’s new Liquid Glass navigation animations and I have the compatibility flag on on Info.plist (UIDesignRequiresCompatibility set to True). I am wondering if there is a solution or workaround that preserves the old design (until Liquid Glass adoption) or otherwise explains how to avoid the jump, if possible.

What I’ve already tried

Checked Xcode console for warnings — none relevant. Verified behavior on Simulator and real devices. Tried setting navigationItem.backButtonDisplayMode / setting explicit (empty) back button title to remove label layout changes. No improvement. Considered removing UIRequiresDesignCompatibility (which makes app adopt Liquid Glass) — that appears to avoid the mismatch, but I need to know if there’s a way to keep compatibility mode and avoid this jump. Tried ensuring consistent largeTitleDisplayMode on root/detail (no effect).

Questions

Is this a known iOS 26 beta bug / expected behavior when UIRequiresDesignCompatibility is set? Is there a recommended workaround that preserves the compatibility (old look) without the back-button jump? Are there UINavigationBarAppearance or transition APIs I can override to prevent the system attempting the new “merge” animation while running in compatibility mode?

Extra details

App uses custom subclasses for tab and navigation controllers; the behavior reproduces with plain UINavigationController too. Only one main tab in the app (so it’s always root-from-tab scenario). No third-party layout engines are involved.

Thanks — I can paste logs, screen recordings, or a sample project if that helps. Any guidance appreciated.

How to C with GUI in Mac OS? [closed]

How to inspect structures like NSRect/NSSize using lldb?

noemail@noemail.org (Marek H) — Thu, 30 Oct 2025 11:42:11 GMT

I have previously used lldb to print structures like NSRect or NSSize of 3rd party processes without issues. But I am struggling in modern versions of Xcode to inspect them. Namely since the introduction of Xcode 15 and dwim-print I am struggling with printing structures. I want to state everything works on binaries that were compiled by me. However if I attach to another processes such as PhotoBoot.app (SIP disabled) I cannot even print frame on NSWindow. Yet it is nicely shown by Xcode view hierarchy.

(lldb) e @import AppKit
(lldb) po (NSRect)[[[NSApp windows] firstObject] frame]
error: <user expression 16>:1:9: attempt to use a deleted function
1 | (NSRect)[[[NSApp windows] firstObject] frame]
|         ^
note: /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX15.5.sdk/System/Library/Frameworks/CoreFoundation.framework/Headers/CFCGTypes.h:77:13: destructor of 'CGRect' is implicitly deleted because field 'origin' has no destructor
   77 |     CGPoint origin;
|

I have found workarounds but I am confused on how to use dwim-print

Wrapping it in NSValue (boxable)

(lldb) po [[(NSWindow*)0x13c606800 valueForKey:@"frame"] description]
NSRect: {{434, 480}, {692, 550}}

Manually finding offset of CGRect structure within NSWindow class

(lldb) p (ptrdiff_t)ivar_getOffset((struct Ivar *)class_getInstanceVariable([NSWindow class], "_frame"))
(ptrdiff_t) 224
(lldb) p (CGRect *)(0x13c606800 + 224)
(CGRect *) (origin = (x = 434, y = 480), size = (width = 692, height = 550))

Please do not suggest NSStringFromRect or casting to NSWindow as it doesn't work as well. I repeat everything works if I run my own app (doesn't work in 3rd party apps.)

Xcode 16.2 and Xcode 16.2 beta "The tunnel connection failed"

noemail@noemail.org (Kawthar Al-Tamimi) — Tue, 24 Dec 2024 08:16:07 GMT

I have installed iOS 18.3 on my iPhone SE (second generation) after installing the beta version it stops running on my device.

I have already tried to install the Xcode 16.2 beta version and did the settings on Xcode (sudo xcode-select -s /Applications/Xcode-beta.app/Contents/Developer).

but still got this error "Previous preparation error: The tunnel connection failed while the system tried to connect to the device.; The tunnel connection failed while the system tried to connect to the device."

also I tried to turn off the beta version on my iPhone but unfortunately, I still got the same issue now.

I tried every solution from cleaning the caches and everything to restarting my Mac and iPhone but nothing worked and I don't want to erase the iPhone and back to the older version.

Any suggestions?

Xcode: What is a target and scheme in plain language?

noemail@noemail.org (MichiZH) — Tue, 17 Dec 2013 14:59:23 GMT

Yeah the title says it :-) What do they mean in plain English language? I really don't understand the explanation on Apple's website and I need to rename my target and I'm afraid that nothing works after that..

Double-quoted include [all Facebook SDK imports], expected angle-bracketed instead

noemail@noemail.org (JeffB6688) — Wed, 19 May 2021 19:04:28 GMT

I am getting the following warning in iOS Xcode builds:

    Double-quoted include "FBSDKDeviceLoginCodeInfo.h" in framework header, expected angle-bracketed instead.

This is apparently a new default warning in Xcode 12 which will throw a warning anywhere you #import or #include with "quotes.h" instead of <brackets.h>.

I am getting this for all of the Facebook SDK imports. There are a few StackOverflow proposed solutions out there, but none of them works.

These solutions do not work:

go in the project's Build Settings a just set the option Quoted Include In Framework Header to No :
you can use Cocoapods version 1.10.0.rc.1 temporarily until 1.10.1 is officially available -> gem install cocoapods -v '1.10.0.rc.1'

Another option is to update your Podfile (add below code) to disable the warning flag CLANG_WARN_QUOTED_INCLUDE_IN_FRAMEWORK_HEADER setting for all pods in your project

post_install do |installer|
  installer.generated_projects.each do |project|
    project.targets.each do |target|
      target.build_configurations.each do |config|
          config.build_settings['CLANG_WARN_QUOTED_INCLUDE_IN_FRAMEWORK_HEADER'] = 'NO'
      end
    end
  end
end

You can disable these warnings for your entire project by navigating to your project's "build settings", finding the field "other linker flags" and adding the following flag: -Wno-quoted-include-in-framework-header

Worked for me:

rm -rf ~/Library/Developer/Xcode/DerivedData/
rm -rf ~/Library/Caches/CocoaPods/
pod deintegrate
pod update

These solutions were written 7 or 8 months ago and DO NOT WORK FOR ME. Are there any new solutions beyond manually editing hundreds of occurrences of this?

Why to add icons in info.plist file?

noemail@noemail.org (TechChain) — Tue, 28 Jun 2016 06:06:13 GMT

I have added required icons files in my app. But when I upload app to app store then it shows me an error saying Bundle does not contain icon file 57*57 but in my app I already have it.

I developed this app in Xcode 5 then that time I added icons in info.plist because on some of devices icons were not visible.

<dict>
        <key>CFBundlePrimaryIcon</key>
        <dict>
            <key>CFBundleIconFiles</key>
            <array>
                <string>icon76</string>
                <string>icon40</string>
                <string>icon40@2x</string>
                <string>icon60@2x</string>
                <string>icon40@3x</string>
                <string>icon50@2x</string>
                <string>icon50</string>
            </array>
            <key>UIPrerenderedIcon</key>
            <true/>
        </dict>
    </dict>

So why do we add icons in plist because in my latest project in xcode 7 I did not add icon name in plist still it was uploaded on app store.

UPDATE

 <key>CFBundleIcons</key>
    <dict/>
    <key>CFBundleIcons~ipad</key>
    <dict/>

used above code in plist & tried to run it does not show any icon

How can I get XCTest to wait for async calls in setUp before tests are run?

noemail@noemail.org (Brett Elliot) — Wed, 8 Apr 2015 02:13:15 GMT

I'm writing integration tests in Xcode 6 to go alongside my unit and functional tests. XCTest has a setUp() method that gets called before every test. Great!

It also has XCTestException's which let me write async tests. Also great!

However, I would like to populate my test database with test data before every test and setUp just starts executing tests before the async database call is done.

Is there a way to have setUp wait until my database is ready before it runs tests?

Here's an example of what I have do now. Since setUp returns before the database is done populating I have to duplicate a lot of test code every test:

func test_checkSomethingExists() {

    let expectation = expectationWithDescription("")
    var expected:DatabaseItem

    // Fill out a database with data. 
    var data = getData()
    overwriteDatabase(data, {
      // Database populated.
      // Do test... in this pseudocode I just check something...
      db.retrieveDatabaseItem({ expected in

        XCTAssertNotNil(expected)

        expectation.fulfill()
      })
    })

    waitForExpectationsWithTimeout(5.0) { (error) in
        if error != nil {
            XCTFail(error.localizedDescription)
        }
    }

}

Here's what I would like:

class MyTestCase: XCTestCase {

    override func setUp() {
        super.setUp()

        // Fill out a database with data. I can make this call do anything, here
        // it returns a block.
        var data = getData()
        db.overwriteDatabase(data, onDone: () -> () {

           // When database done, do something that causes setUp to end 
           // and start running tests

        })        
    }

    func test_checkSomethingExists() {

        let expectation = expectationWithDescription("")
        var expected:DatabaseItem


          // Do test... in this pseudocode I just check something...
          db.retrieveDatabaseItem({ expected in

            XCTAssertNotNil(expected)

            expectation.fulfill()
        })

        waitForExpectationsWithTimeout(5.0) { (error) in
            if error != nil {
                XCTFail(error.localizedDescription)
            }
        }

    }

}

Xcode/Simulator: How to run older iOS version?

noemail@noemail.org (Shai UI) — Tue, 23 Nov 2010 23:16:44 GMT

I'm thinking of upgrading to iOS SDK 4.2. But what I'm wondering is if I'll still be able to run the simulator as iOS 3.2. This is because I'm creating iAds for iPad but I still want to check if my program will run with iOS 3.2.

Note: I have seen a similar post to this in the past, but they weren't really helpful in giving the exact steps in how this could be done.

Swift Package Manager stuck on loading screen forever

noemail@noemail.org (Plato) — Fri, 25 Oct 2024 13:07:16 GMT

SPM loads indefinitely as seen below. I cannot add any packages.

Whether I enter a URL, or don't enter a URL, this screen is loading forever.

Have tried deleting DerivedData folder (~/Library/Developer/Xcode/DerivedData) as well as SPM caches (~/Library/Caches/org.swift.swiftpm/), does not help.

Have made sure that I've committed my code to a git repository, and followed the advice here.

This is the first package I'm adding—I can't add any packages, generally.

This problem exists for all my Xcode projects.

Building a Unity project into iOS without Xcode

noemail@noemail.org (user12867493) — Sat, 15 Sep 2018 17:01:02 GMT

I want to build my Unity project to the iOS platform.

When I click build to iOS I get prompted with this screen:

There says Run in Xcode as but I do not have a Mac, but correct me if I am wrong but you can not run Xcode on Windows.

So is there no way I can build my project without a Mac then?

Swift warning about possible isolated conformance of "some View"

noemail@noemail.org (tmlen) — Wed, 22 Jul 2026 23:36:59 GMT

This code:

import SwiftUI

@MainActor
func renderImage(_ view: some View) -> CGImage? {
    let renderer = ImageRenderer(content: view)
    return renderer.cgImage
}

let image = renderImage(
    ZStack {
        Image(systemName: "drop.fill").foregroundStyle(.white)
        Image(systemName: "drop").foregroundStyle(.black)
    }.font(.system(size: 30))
)

Compiles but shows warning:

Conformance of underlying type of 'some View' to protocol 'View' may be isolated and cannot be passed to main actor-isolated context

Xcode 27.0 beta 4
Swift Concurrency Checking: Complete
Approachable Concurrency: No
Default Actor Isolation: nonisolated

If I understand correctly:
The issue seems to be that .font() returns an opaque type "some View".
And "some View" may also conform to View only constrained to some actor.
(as in "struct A: @someGlobalActor View").

But renderImage() is @MainActor, and thus the view it is passed, needs to conform to View from the main actor. renderImage() needs to be @MainActor, because ImageRenderer.init() is @MainActor.

Is there any way to fix this warning?

I'm new to Fastlane. Does anyone know how to fix this error from running

fastlane ios myLane.

The output:

[12:50:11]: fastlane finished with errors

[!] Unable to locate Xcode. Please make sure to have Xcode installed on your machine

But I have the newest Xcode (9.3.1) installed from Mac App Store.

Environment info:

fastlane --version

which is the newest version.

How to add frame in mkmapview

noemail@noemail.org (iPhone) — Mon, 12 Sep 2011 05:42:08 GMT

I have a MKmapView in my application. Now I want to add frame im my MKmapView. I have written the code as follows:

- (id)initWithFrame:(CGRect)frame
{
        // Initialization code
        
        time=[[UILabel alloc] initWithFrame:CGRectMake(10, 10, 200, 21)];
        time.textColor=[UIColor blackColor];
        [time setFont:[UIFont boldSystemFontOfSize:18]];
        [time setBackgroundColor:[UIColor whiteColor]];
        [time addSubview:time];
        time.alpha=0.8;
    return  time;
}

but the frame does not appear in my MKmapView. How can I achieve that?

Null value generates while converting the date from one format to another format

noemail@noemail.org (iPhone) — Wed, 16 Nov 2011 12:02:52 GMT

I am having a date format "16-11-2011", but I want to convert it into "16 Nov". I've written the code for it but null value generates instead of the format "16 Nov"

For this I have written following code

NSDate *checkIn = [[NSUserDefaults standardUserDefaults]valueForKey:@"CHECK_1"];
    NSLog(@"Date: %@",checkIn);
    
    NSDateFormatter *formatter = [[NSDateFormatter alloc] init];
    
    [formatter setDateFormat:@"dd MMM"];
    NSString *checkInDate = [formatter stringFromDate:checkIn];
    NSLog(@"checkInDate:%@",checkInDate);

and the results display by nslog statements are as follows:

Date: 16-11-2011
checkInDate:(null)

How can I convert it into the format that I want?

Unsupported compiler 'com.apple.compilers.llvm.clang.1_0' selected for architecture 'x86_64' on Xcode 8.3 beta_2

noemail@noemail.org (Karan Thakkar) — Thu, 16 Feb 2017 08:54:34 GMT

I'm annoyed by this error that I'm getting and the fun fact is none of the solutions posted online seem to work for me.

Unsupported compiler 'com.apple.compilers.llvm.clang.1_0' selected for architecture 'x86_64'

Also I found a solution where someone said to change the

Xcode > Target > Build Settings > Build Options > Compiler for C/C++/Objective-C

Select Default compiler (Apple LLVM x.y)

I cannot find this option, See this:

Any help would be appreciated.
