I read that phrase 5 times. Is that really true? Only subclasses of NSManagedObject get managed persistency from Core Data?
That would be what the sentence is saying. By my read, the following sentences describes why:
The NSManagedObject class implements the functionality needed to fully integrate into the Core Data framework and can represent any entity.
Of course, that sentence doesn't tell us what functionality is needed there, but you'd expect that there would be lots of interesting stuff happening under the covers in NSManagedObject so that Core Data can do it's auto undo/redo magic and the persistent store logic.
