Summary:
In a basic app using Core Data, I created two entities in the data model, with a relation between them, then created NSManagedObject subclasses of both. One of the implementation files attempts a failing import:

#import "NSManagedObject.h"

This should be:

#import <CoreData/NSManagedObject.h>

But more importantly, this isn’t needed, because the header file imports <CoreData/CoreData.h>. The attached project shows the problem.

Steps to Reproduce:
1. Create a single view iOS app that uses Core Data.
2. Add entities to the data model to model a basic to-do list: Task and List entities, with a one-to-many relationship between them.
3. Use the Editor > Create NSManagedObject subclass menu item to create classes for these two entities
4. Attempt to run the app. Build will fail because NSManagedObject.h cannot be found 

Expected Results:
Generated NSManagedObject subclass files will not attempt to import NSManagedObject.h

Actual Results:
Generated NSManagedObject subclass files DO attempt to import NSManagedObject.h, causing a build failure

Regression:


Notes:
The attached project shows the problem. I did not make any changes to the List.h/m or Task.h/m after using the “Create NSManagedObject subclass” menu item to create them.
