I just upgraded to Version 16.0 (16A242d) and unfortunately the App that used to run perfectly fine on Xcode 15 is now broken. It crashes right after showing the Launch Screen on the Simulator. Here's the formatted error message in the Console:
dyld[80159]: Library not loaded: @rpath/AppName-iOS.debug.dylib
Referenced from: <App ID> /path/to/AppName-iOS.app/AppName-iOS
Reason: tried: '/path/to/DerivedData/AppName-iOS.debug.dylib' (no such file),
'/path/to/CoreSimulator/Runtimes/iOS.simruntime/Contents/Resources/RuntimeRoot/usr/lib/system/introspection/AppName-iOS.debug.dylib' (no such file),
'/path/to/AppName-iOS.app/AppName-iOS.debug.dylib' (code signature not valid for use in process: Trying to load an unsigned library),

For some reason the Library is unsigned and I've checked all the settings with no luck.
