Core Data Codegen fail in Xcode 8

Question

I have an iOS app containing a Core Data model with 6 entities. The entity Name is set up as follows:

Class Name: Name

Answer 1

Looks like Xcode 8.2.1 won't turn off codegen. But you can manually delete codeGenerationType="category" from .xcdatamodel contents file.

Close Xcode, delete codeGenerationType, delete DerivedData folder and rebuild.

Will wait for fix in future releases.
