Xcode生成NSManagedObject子类问题

Question

After I set up Core Data Stack, I generated the NSManagedObject Subclass automatically.

However, I received the error in xcode 8, which is very annoying.

Answer 1

So I also ran in this issue. You have to disable automatical code generation if you want to create the NSManagedObjects by yourself. So there are different ways. First way is go to your model and changed the Toolversion to xCode 7.3. In every entity you can set the Codegen to Manual/None like in the Screenshot. Clean your project, and try again! I hope this was helpful.
