Same problem here...

I had this problem after copying files from a Core Data project to one where I wanted to use Core Data, but hadn't chosen it at project creation. It needed the import for CoreData.h in the "ProjName-Prefix.pch" file in the "Supporting Files" directory.

#ifdef __OBJC__
    #import <UIKit/UIKit.h>
    #import <Foundation/Foundation.h>
    #import <CoreData/CoreData.h>

#endif

That did it for me anyhow.

In general: The error is caused by a missing import statement. Import the class that is used and the error will disappear.
