The case in point here is that -[NSManagedObjectContext executeFetchRequest:error:] returns an NSError if something goes wrong.

This is misleading. The fundamental behaviour is that method returns NO if something goes wrong. In addition, if the error parameter is non-NULL and something goes wrong, the parameter contains an NSError that describes the problem.
