Bug Project won't build using Xode15 release candidate.

Updating the Unity version in Unity hub from 2022.3.9f1 to 2022.3.10f1 will solve the problem immediately, with no extra hurdles.

 

Thank you so much - this did the trick for me! ... I updated MacOS and updated Unity to 2022.3.10f1 - now I'm happy building again!

 

Thanks a lot, this helped me.
Uninstalled xcode 15 and installed xcode 14.3.1
And I could build again

 

Hey there, I'm using XCode 15 RC, MacOS Ventura 13.6 and my iPhone 13 is iOS 17, using Unity 2021.2.5f
While the Xcode build is working, I cannot use Metal Frame Capture (I go to the Edit Scheme -> Options -> Capture GPU Frame -> select Metal, and in Build Configuration I select Release). Any idea why that is? This did work back in iOS 16 and XCode 14.3, while still using this same Unity version.

 

That works for me as well. Thanks, @dmarqs and @drewjosh for adding more details.
I'm using Unity 2023.1.16 + Xcode 15.0
And here is my contribution to make it even easier:

 

For everyone that is still experiencing the problem even if you've got Sonoma + Xcode 15.0 + 2022.3.10f1, try the following:

1. Quit Unity
2. From your game's iOS build folder, delete everything.
3. From your game's Unity main project folder, delete the Library and Temp folders.
4. Re-open your project and let Unity do all the re-importing.
5. Build again and see if it works.

 

I have the same problem here with Unity 2022.3.10 and Xcode 15 -> Two Errors :

- Assertion failed: (false && "compact unwind compressed function offset doesn't fit in 24 bits"), function operator(), file Layout.cpp, line 5758.

and

- Linker command failed with exit code 1 (use -v to see invocation)

 

Try adding the `-ld64` following the steps:

Just like some here, this issue was not solved by upgrading Unity to 2022.3.10f1. In order to simplify the process for everyone here is a post build script to resolve the issue. Happy Coding!

Code (CSharp):

1. using System.IO;
2. using UnityEditor;
3. using UnityEditor.Callbacks;
4. using UnityEditor.iOS.Xcode;
5. using UnityEngine;
6.  
7. public class AppleBuildPostProcessor: MonoBehaviour {
8.   [PostProcessBuild(1)]
9.   public static void OnPostProcessBuild(BuildTarget target, string path) {
10.     if (target == BuildTarget.iOS) {
11.       ModifyValues(path);
12.     }
13.   }
14.  
15.   private static void ModifyValues(string path) {
16.     var projectPath = PBXProject.GetPBXProjectPath(path);
17.     var project = new PBXProject();
18.     project.ReadFromFile(projectPath);
19.  
20.     project.AddBuildProperty(frameworkTargetGuid, "OTHER_LDFLAGS", "-ld64");
21.  
22.     project.WriteToFile(projectPath);
23.   }
24. }

 

This breaks Odin Serialisation on iOS.

 

this seems no longer true

 

Sonoma, xcode15,
Report https://issuetracker.unity3d.com/is...latforms-fails-with-xcode-15-dot-0b6-or-newer implies that the issue has been fixed.

I am still getting:

ld: Assertion failed: (false && "compact unwind compressed function offset doesn't fit in 24 bits"), function operator(), file Layout.cpp, line 5758.



clang: error: linker command failed with exit code 1 (use -v to see invocation)

The solution is not to write hacky post process scripts or

-ld_classic

flags, butUnity should fix the issue to their product.

 

Download Xcode beta 15 version 5 and placing it in the Applications folder worked for me.
Plus
> Unity Framework > Build Settings > Other Linker Flags (you can search for it) > double click on value + hit plus on button > add "-ld64" > hit Enter >

 

This isn't solving it for me with Xcode 15.0.1 and Unity 2022.3.11f1. Having Beta 5 alongside the latest version was working until these latest updates, and now it's broken again with the same errors.

Assertion failed: (false && "compact unwind compressed function offset doesn't fit in 24 bits"), function operator(), file Layout.cpp, line 5758.

Linker command failed with exit code 1 (use -v to see invocation)

 

Did you add "-ld64" or "-ld_classic" in other linker flags for Unity Framework?
Also, please share the detailed screen shot of the error. Thanks

 

These flags break functionality in Odin Serialization and who knows what else. My fix right now is to go back to xcode 14 which doesnt work on sonoma.

 

It appears from my own testing that the -ld64 or -ld_classic linker is only needed if the minimum iOS target is less than 15.0. Whether or not you want to exclude anyone on iOS 14 and below is another question.

 

Unity 2022.3.12f1 fixed this error for me

changed!
After 5 days, I have build my project and again the same problem ( can't understand what realy happen

New solution was for me downgrade to Xcode 14 with Sonoma, but the build result is success!

here is the link how you can downgrade to Xcode 14 with Sonoma

Upgrading from 2023.1.12f1 to 2023.1.18f1 fixed it for me.

 

Unfortunately not for us, but with the workaround (-ld64) it works.
