In Xcode 15 beta 3 and iOS 17 beta 3, my app with SwiftData keeps generating error: *** Terminating app due to uncaught exception 'NSUnknownKeyException', reason: '[<NSManagedObject 0x2811cb390> setValue:forUndefinedKey:]: the entity dataSets is not key value coding-compliant for the key "(null)".' I have a model: @Model final class Station: Sendable { ... var dataSets: [String] } The error seems to occur when saving entities of the model in SwiftData. There is no entity named "dataSets".

In iOS 16 beta 3, my iOS app sets some strings in the shared user defaults of the app group.
