Bug Unity 2021.3.6f1, Xcode 14, iOS 16 Problem: UnityFramework crash before main()

Hi, I`ve recently updated to Xcode 14 and my devices to iOS 16.

I created a new Unity project (only one cube), and added the exported UnityFramework to the new iOS project. After running, it crashed before the main() function. But it can work normally on iOS 15 devices

 

same problem here.

 

Im having the same Issue

 

I have done some experiments using Xcode13 and Xcode14. The current conclusion is that Xcode13 + iOS 16 is normal, but Xcode 14 + iOS 16 will crash

Has any friend solved this problem?

Also having the same problem, can build and launch through Xcode 14 on device running iOS15 but on device with iOS16 I get the InitializeMemory error.

NOTE: I can, however, launch the app on iOS16 and then attach the debugger after launch. But that method doesn't seem to give me any debug output, I can see performance and memory stats though.

 

We are experiencing the same issue here...
App runs fine on iOS 14.6, but crashes on iOS15 and 16. Tried Xcode 14 and 13.4.1 and both crashed.
We have fully up to date Playfab and Firebase SDKs in the project.

 

Same here...

After disabling the Thread Performance Checker in the Scheme, this error wasnt showing up anymore.

 

I have the same problem with Xcode 14 and iOS 16 any ideas about what is wrong?

 

It`s useful! Thanks!

 

This worked for me as well. Is there an easy way to set this automatically in OnPostprocessBuild?

The API for UnityEditor.iOS.Xcode.PBXProject is pretty functional, but UnityEditor.iOS.Xcode.XcScheme is lacking, and it seems like the only way is to parse the XML, insert disablePerformanceAntipatternChecker = "YES" into LaunchAction, and write it back.

Is there a cleaner way?

 

Thanks for your temporary solution. I implemented your solution to post process. Anyone looking for an automated solution can use this. Just create a script with named "PostProcessForFixXcodeCrashBug.cs" in Editor folder and paste the codes below into that script:

(My suggestion is make sure Xcode app is completely closed before you start the take iOS build from Unity)

but ,when u used the meta capture 2 analyze the gpu profile,it crash too!

 

This issue still in unity 2022.2.9

 

I run on iphone 13, iphone 12 and this issue capture in xcode. I update to unity 2022.2.11 but nothing changed.

 

This is my error

 

I get this error in editor when build addressable: Failed to create Physics Mesh from source mesh "xxxx". One of the triangles is too large. It's recommended to tesselate the large triangles. Is this cause crash?

 

After I backup my project to unity 2021.2.4, iOS device run normal

 

I think it has to do with memory

 

Hi!
I am experiencing a similar crash on startup. I am using Unity 2021.3.23f1.

 

The issue still persists in a framework built from Unity 2022.3.8f1. Disabling Thread Sanitizer is not a solution, so I hope someone from Unity will pay attention.

To add to the context: in my case, I intentionally link the framework to my executable at launch-time[1], which is contrary to the proposed way of loading and linking the framework at runtime. I don't want framework vendors to dictate the way I link the framework to my app.

What this issue exposes is that there are some nasty concurrency bugs in the *framework initialization* process (hence a crash during linkage) which are hidden when the framework is linked during runtime. This means the initialization process is unstable and may cause unpredictable crashes during runtime, which will be very hard to debug when the app is in production.

Considering the approaching release of VisionPro, I urge the maintainers of the Unity iOS framework to investigate the issue.

[1] This is because I maintain versioning of all third-party packages through Swift Package Manager. To make this work, I manually wrap the framework in a package. Unfortunately, there is no option to embed and not link the framework this way (which is okay and aligned with iOS development best practices, contrary to the linkage solution proposed by Unity).

P.S. To properly wrap the framework in SPM, I should manually patch some source files to make the resulting module map semantically correct. This, alongside some other things like the disabled "BUILD_LIBRARY_FOR_DISTRIBUTION" flag, shows that developers responsible for the Unity framework were not aware of the best practices of library distribution on Apple platforms. I urge devs to pay attention to these issues and would be glad to assist if necessary.

 

iPhone 14 Pro, iOS 16.6.1

 

I HAVE THE SAME PROBLEM in 2023.2.0f.

1. Adding `import UnityFramework` to the `@main` AppDelegate.swift makes app fail to launch at all.
2. Removing `import UnityFramework` makes app work.

PLEASE HELP!!!

I think one of Unity's packages may be causing this (the latest I added were Cinemachine, 2D Sprite, 2D Pixel Perfect, Etities and URP).

Xcode: 15.0.1
MacOS: 14.1.1

 

I also have the same problem. I exported the iOS project from the Unity project, then compiled the UnityFramework static library and used it for another iOS project. This project crashed as soon as it started. See the screenshot of the crash report. My development environment is as follows:
Unity: 2021.3.23f1c1
Xcode:15.3
iOS: 17.4

Even if it is an empty Unity project, it will crash in the end. If you turn off Xcode's Thread Performance Checker, it can run normally, but I think this is just a temporary solution and not a good practice. With the same Unity version and Xcode version, the program runs normally on iOS 15.4.1. I hope Unity engineers can Help me solve the problem. I need to use the packaged UnityFramework to other companies. They may use the latest Xcode and the latest iOS system for testing.
