Answer 1

NSManagedObject is defined in a .h file that is included by <CoreData/CoreData.h>. Therefore, you do not need to declare it, and you do not need the #import statement.

Answer 2

Have same issue when I created NSManagedObject subclass in workspace.

Use follow declaration then the problem gone.

#import <CoreData/NSManagedObject.h>
