More info:
The issue happened when I added an attribute in an entity. And also happened when adding an entity to the same model.
The code I'm using to add the persistent store is:
try persistentCoordinator.addPersistentStore(ofType: NSInMemoryStoreType, configurationName: "InMemoryStore", at: nil, options: myOptions)
try persistentCoordinator.addPersistentStore(ofType: NSSQLiteStoreType, configurationName: "PersistentStore", at: myGroupURL, options: myOptions)
In case it fails, I delete the DB and recreate it.

Update on this Q: Apple replied to a feedback I opened saying Xcode does not have official support for Rosetta. I had no option but to put an enormous effort into adding support to Apple Silicon Macs. Thanks, Apple.
Is it working for you guys in beta 4 of Xcode?
I'm also having a problem with AVAudioEngine, but is when I call the prepare method. It works fine in iOS 13 simulator, but crashes in iOS 14.
This is the error I got:
AQDefaultDevice (1): output stream 0: null buffer
EXCEPTION thrown (-50): error != 0
AQDefaultDevice (1): output stream 0: null buffer
Initialize: Mach message timeout. Apparently deadlocked. Aborting now.
