Cannot create an NSPersistentStoreCoordinator with a nil model

Question

Been having my first crack at Core Data and I\'m getting the following error when running my code on my device, but it works fine on the simulator..

Answer 1

I solve the problem without changing any code.

I add the ModelName.xcdatamodeld through File->Add File instead of dragging the file into the Xcode.

 NSString *path=@"ModelName";

NSURL *modelURL = [NSURL fileURLWithPath:[path stringByAppendingPathExtension:@"momd"]];

model = [[NSManagedObjectModel alloc] initWithContentsOfURL:modelURL];
