I’m encountering an issue since I started using Xcode 16. I have a widget in my app, and I'm trying to organize the code by splitting it into different files for better structure. However, when I do this, I get an error: error: Unexpected input file: /Users/******/Desktop/TestApp/TestAppWidget/Provider.Swift (in target 'TestAppWidgetExtension' from project 'TestApp') I want to emphasize that if I keep all the code in one file, everything works fine. I've checked the Target Membership, and it's set up correctly. but I don't understand why this is happening only in Xcode 16. Has anyone else experienced a similar issue or has any ideas on why this is occurring? I would appreciate any help!

I have been working on Task Management app for macOS (currently using maOS 15.0 on a M1 MacBook Pro) for a while. Nothing fancy, it uses SwiftUI and Core Data. My problem: I make changes to the app, then run it in the simulator and see if everything works as expected. This works fine for maybe three weeks, until at one point it suddenly stops working – I make a minor change, click "Run" in Xcode (this happens in Xcode 15.x and now Xcode 16), the app icon bounces in the dock, but then no window opens. The app is built and I can see in the console that there are the usual notifications, but I cannot use the simulator anymore. I tried cleaning the Build Folder, resetting the Computer, reinstalling Xcode – nothing helps. What occasionally helps is renaming the Bundle Identifier, but now I only got it to run the simulator once more, then it stopped working. The only solution I have is to manually rebuild the whole app under a new name – that is, recreating the Core Data model and all files, which I have done three times. And now it stopped working again. Does anyone know why this could be? I think Xcode 16 gives me a notification I did not get from Xcode 15: "NSBundle file:///System/Library/PrivateFrameworks/MetalTools.framework/ principal class is nil because all fallbacks have failed" I could not find anything on this. Any ideas are greatly appreciated.

I posted this as a reply.to a previous post, but got no reply, so here is a new post. I'm using. user defaults in an app with a self defined suite name. I had put aside work on the app for several months, and after returning to work on it, I'm getting xcode messages when testing, several like: "Not updating lastKnownShmemState in CFPrefsPlistSource<0x600000358360> (Domain: mySuiteName, User: kCFPreferencesCurrentUser, ByHost: No, Container: (null), Contents Need Refresh: Yes): 1169 -> 1181" Can anyone tell me what is wrong or point me to an answer.

When using Instruments in Xcode 15.3 on macOS Sonoma 14.3.1 symbols from system frameworks are not displaying. I've tried creating a template "App" project and running it on the iOS 17.4 simulator without any code changes and still am not seeing symbols so I can be sure it's not unique to my real-world project build settings. If I install Xcode 15.0 and run the same build in the same 17.4 simulator using Instruments 15.0 it shows thread names and symbols for UIKit and other frameworks but is still missing SwiftUI symbols. Instruments 15.3 Instruments 15.0 I've spent 2 days trying to narrow down why I couldn't debug my app and even deleted all my partitions and reinstalled macOS which didn't fix the issue.

We are experiencing an issue with withCheckedContinuation in our Swift project. Our implementation was working perfectly in a previous version of Xcode and continues to work in the simulator. However, it fails to work on a real device. Here’s a brief description of the problem: • Environment: - Xcode Version: Xcode 16.0 Beta 5 - Swift Version: Swift 5 - OS: IOS18 beta 5 • Problem: The code using withCheckedContinuation behaves as expected in the simulator but fails on a physical device. We are receiving a “bad access to memory” error when running on a real device. • What We’ve Tried: 1. Verified that the code works in previous Xcode versions. 2. Tested on different simulators, where it runs without issues. 3. Checked for any obvious errors in memory handling or threading. Code Example: Here’s a simplified version of the problematic code: var body: some View { VStack { Text("Hello, world!") } .padding() .onAppear { Task { await self.checkTrialOrIntroductoryDiscountEligibilityAsync() } } } func checkTrialOrIntroductoryDiscountEligibilityAsync() async { return await withCheckedContinuation { continuation in checkTrialOrIntroDiscountEligibility() { continuation.resume() } } } func checkTrialOrIntroDiscountEligibility(completion: () -> Void) { completion() } }

The XCode connection to my local git server for pushing does not work. I've added a remote origin to my project pointing to the local git server. Pulling from that server via xcode works. But pushing to this server results in a dialog popping up. this dialog says "The repository rejected the provided credentials" and asks me to select the connection method and the certificate file. When I select the certificate file and press ok then the same error cmes again. Doing the git push via commandline works without a problem.

hey all today for some reason im getting Unsupported SDK or Xcode version valdation failure when uploading to app store connect. I haven't changed anything and i was able to upload jsut a few days ago with same version of xcode. Its xcode 16.0 anyone else getting this? Maybe its a server side issue?

Since its update to iOS 18.0, I have not been able to use the Simulator in Xcode at all. It is stuck loading for a very long time, and then it crashes. I managed to get it to start once, but it used up all of my system's memory immediately. I have not had any problems with the Simulator before the iOS 18.0 update. Additionally, after the Simulator crashing, the StoryBoard usually stops working as well, until I restart Xcode. (I use an M1 MacBook Air with 8GB of RAM)

Bug in IOS18 / Xcode 16. The code works fine on a IOS17 sim but on an IOS18 simulator or device errors are show when using custom colors names. Like .text4.

In the latest version of Xcode, breakpoints are not displaying correctly, making it difficult to track code behavior. Previously, Xcode allowed you to step through each function, showing clear execution steps and allowing interaction to debug effectively. However, now it only shows memory addresses without providing meaningful insights, limiting the ability to interact with or test the code as it's being developed. Is anyone else experiencing this issue, or does anyone know of a workaround?

I'm using Unity to create a VisionOS project. Using Polyspatial. I want to be able to use WeatherKit. I can not seem to create a VisionOS plugin in Unity. I've found all sorts of resources for building one for iOS. I made small changes to convert to VisionOS, but no matter what I do, I get 'Undefined Symbol' errors when I try to build the XCode project. Most recently I used this github for reference https://github.com/Robert-96/unity-swift/tree/main Am i trying to do something that just isn't possible for VisionOS?

When I try to run my app on my iPhone, from Xcode, I get a popup that says Unable to Install "AppName". There is some text in the popup. Here's the first part of it.

In the first Xcode 16 beta, none of my SwiftUI previews work - they all just crash on start up. Has anybody run into this and found a workaround? Have tried all the usual steps of cleaning the project/restarting Xcode.

Why won't XCode 16 run without iOS 18 installment?

Since a few days now, I'm using Xcode 16 and I try to install a newly made provisioning profile for my app. On the development profile I always get the message "Failed to install one or more provisioning profiles on the device". But no message at all for the distribution profile. I even tried setting up completely new certificates as I updated to macOS 15 and Xcode 16. No success. When checking the installed profiles via Finder under open ~/Library/MobileDevice/Provisioning\ Profiles I only see profiles from my last project from june this year. It does not matter how often I press "Download Manual Profiles" in Xcode nothing new lands here. Is there any other way to install newly created profiles? As my project is done with .NET and not a native Xcode project I do not have the option to let Xcode it generate for me (if this would even work).

Here's a concise post for the Apple Developer Forums: Title: Swift Macro for SwiftUI Previews Not Recognized in Xcode Hello everyone, I've developed a Swift macro swift-inject-preview that generates SwiftUI previews (PreviewProvider or #Preview). However, Xcode seems to ignore the previews generated by the macro, likely because it searches for PreviewProvider/#Preview or similar text in the file before macro expansion. Has anyone encountered a similar issue or found a workaround for getting Xcode to recognize previews created through Swift macros? Any help or insight would be greatly appreciated! Thank you!
