NSManagedObjectModel initWithContentsOfURL returns nil eventhough the modelURL is valid

my NSManagedObjectModel is returning nil eventhough the path is correct. ``` NSString *modelKey = [NSString stringWithFormat:@"/%@/Model", name]; NSString *modelPath = [((Configuration *)[Configuration shared]) stringEntry:modelKey]; NSURL *modelURL = nil; if ( ! [modelPath contains:@"://"] ) { modelPath = PathForBundleResource( modelPath ); modelURL = [NSURL fileURLWithPath:modelPath]; } NSManagedObjectModel *m = [[NSManagedObjectModel alloc] initWithContentsOfURL:modelURL]; ``` NSString *PathForBundleResource(NSString *relativePath) ``` NSString* resourcePath = [[NSBundle mainBundle] resourcePath]; return [resourcePath stringByAppendingPathComponent:relativePath]; ``` I've reset the simulator, did a clean build but nothing helped. I'm new to iPhone programming (core data in particular). Would appreciate any help. Edit: I've edited the original post regarding the xcdatamodeld file. It wasn't linked up properly initially but now it is and still having the same problem. Edit 2: Apparently the name of the xcdatamodel had some variations to the name of the xcdatamodel after linkage. It's working now. Feeling so stupid. Don't know how to delete this question.
