Hello there!
I've encountered the same problem. XCode 16.0 beta 6
Trying to run my app in simulator (runtime for iOS 18.0) gave me the same errors as the OP cited.
Nevertheless, renaming Xcode v.15 did ‘fix’ the problem.
As you said, this is not a real solution. So, I'm perfectly fine with sharing with you the project.
The app is listed on the App Store: https://apps.apple.com/us/app/music-lesson-note-pad/id648631076
If the link doesn’t suffice, I'll send you the project’s archive.

Alas, after relaunching the app - both as a real device and as simulator - the problem resurfaced.
