I\'m using the Swift boilerplate code for Core Data in a fresh project. My .xcdatamodeld file has a single entity defined (Task) with a single attr
This is even frustrated if you tried all the above suggestions and non of them working for me!!
So this is what works for me.
1- Select your xcdatamodeld file
2- Make sure that all your entities has No Module in the "Data Model Inspector", if you see "Model: Current Product Module" ..clear it it so it looks like the attached image.
3- Delete your App to clear core data
4- If still not working, delete your entities and regenerate them.
