Hey Folks,
I am fighting here with a problem. I developed a game on my windows pc. Build it for android and windows (no prob so far).
Now I have to do the same for IOS, but I am a total beginner to use Apple.
I have this issue as described below: I really don’t know what the problem is. Also I can’t have a look into the log file because I really don’t know where the file is. (Apple newb)
So I think there is some data left from windows maybe?
I tried to erase windows as targeted platforms/ deleted the intermediate and save dir/ build everything again/
Anybody an Idea? It is super urgent, because of a close ddl.

Hello, I get the same error when I try to build iOS on MacOS.

My build environment like this:
MacOS 11.6.6
Xcode12.4
UE5.0.1

I try to build iOS IPA in this environment but get the same problems.

ERROR: System.PlatformNotSupportedException: Windows Principal functionality is not supported on this platform.

And I try to search the source code of AutomationTool in Engine/Sources/Programs/AutomationTool/IOS/IOSPlatform.Automation.cs, it seems that the follow code in GetFilesToArchive function cause this problem

if (bXCArchive && !RuntimePlatform.IsWindows)
		{
			// Always put the archive in the current user's Library/Developer/Xcode/Archives path if not on the build machine
			WindowsIdentity id = WindowsIdentity.GetCurrent();
			string ArchivePath = "/Users/" + id.Name + "/Library/Developer/Xcode/Archives";
			if (IsBuildMachine)
			{
				ArchivePath = Params.ArchiveDirectoryParam;
			}
			if (!DirectoryExists(ArchivePath))
			{
				CreateDirectory(ArchivePath);
			}

the WindowsIdentity.GetCurrent() function seems not support on MacOS, but I’am not sure.

Setting “Generate XCode Archive” to false in iOS settings solved the issue for me.

A fix for this issue has been committed and should make it into a future HotFix release. Thanks,
