Hi,

I am using the latest version of XCODE 15, when I run my app on an IOS12 device I got a crash before the app reaches did didFinishLaunchingWithOptions. But when I open XCODE 14 and run the app on IOS12 the app is running fine. I am getting the crash with users devices in the Crashs reports on Organizer.

Here is the crash output:

I was able to fix the problem.

OK. That sounds like a known issue (FB13097713) with the new linker implementation. See the Xcode 15 Release Notes for details. Monitor any future Xcode release notes to be learn about a fix. At that point remove your workaround, just to confirm that the issue is the one we think it is.

I was able to fix the problem. On XCODE 15 go to:

Targets -> Build Settings -> Linking General -> Other Linker Flags
Add:
-ld_classic

It will compile and work on IOS 12
