You are manually generating a NSManagedObject subclass, which has already been generated by Xcode.

Select your entity(Item) -> Goto Data Model Inspector -> Under Class -> Select Codegen -> choose Manual/None.
Now Restart your XCode.

FYI check below image.

I have created simple core data app which helps you to understand basics of how to insert data, delete and update.

take a look here.
