You also can look at SwiftData ... case which uses classes and inheritance for the exact same use case

Just a small side note: SwiftData doesn't use class inheritance (IIRC it doesn't even support it for subentities). The SwiftData PersistentModel is an AnyObject protocol, not a base class, in the context of the original question (and the ModelContext has quite a few [any PersistentModel]'s).
