Anyone got any tips for debugging a crashing SwiftData migration? I'm wondering if it's just easier to do it manually... 😅

It crashes right after the willMigrate, and these errors:

"A Core Data error occurred." "Instances of NSCloudKitMirroringDelegate are not reusable and should have a lifecycle tied to a given instance of NSPersistentStore."

I thought it was this, which fixes the crash, but then my didMigrate code is never ran.

Any tips or ideas?

OK it seems to work if I create a container without CloudKit, then if I actually want a container with CloudKit I create and return that after, just don't use the original container for anything.

Feels gross, but works? I think?

My uber-scientific print statements indicate this takes negligible time, so hopefully fine
