If you generated CoreData subclasses with codegen: ClassDefinition your basically screwed. The only way to fix it is to:

1. Delete your CoreData subclasses.
2. Delete your derived data folder.
3. Clean your project (CMD+K).
4. Generate new CoreData subclasses, this time select Codegen: Manual/None and Module: Current Product Module
