Generating Swift models from Core Data entities

Question

Update for Xcode 8:

In Xcode 8, one needs to go to the Core Data Model Editor and Show the File Inspector. Near the bottom is an option for code gen

Answer 1

You can get Swift model back using NSEntityDescription.insertNewObjectForEntityForName but you must edit your core data model file and not use Person as a Class Entity but .Person else it returns NSManagedObject...

Using println() you won't see Person instance but something like <_TtC5ProjectName4Person: 0xc9ad5f0> but calling methods on this will prove it's a Person instance for real. I guess it's just the way for Swift to generate unique class names, not conflict and CoreData methods show this internal mechanism.

The Apple documentation says:

Swift classes are namespaced—they’re scoped to the module (typically, the project) they are compiled in. To use a Swift subclass of the NSManagedObject class with your Core Data model, prefix the class name in the Class field in the model entity inspector with the name of your module.
