I can't fix this error:
Class not found, using default NSManagedObject instead.
The problem is that the properties of the file xcdatamodeld file are set correctly
Look at this:
I don't understand the problem

The problem is that you specify the Core Data entity Questions
to be of class Questions (rather than NSManagedObject). This is often done to add convenience property accessors and methods.
So you need to provide a Questions subclass of NSManagedObject (or just null the class name in the Core Data editor).
P.S. You probably want to label the class as Question
(singular) rather than Questions
(plural).
