  1. I am trying to add a today extension to my app.

  2. My app includes a cocoaPod (our own cocoapod) which sets up the core data model for our app.

  3. I setup the today extension to use our pod.

  4. On running the today extension target, I get an error for this line.

NSManagedObjectModel *managedObjectModel = [[NSManagedObjectModel alloc] initWithContentsOfURL:[[NSBundle mainBundle] URLForResource:@"MyModel" withExtension:@"momd"]];

The error is that [[NSBundle mainBundle] URLForResource:@"MyModel" withExtension:@"momd"] is nil.

I have set up the group for the app and the extension in the developer store. Wonder why it cannot find the data model in the app bundle?

-- Thanks

You must create app-group for today extension and change storeURL to a location contained in your shared App Group folder:

NSURL *directory = [[NSFileManager defaultManager] containerURLForSecurityApplicationGroupIdentifier:@"group.YourGroupName"];
NSURL *storeURL = [directory URLByAppendingPathComponent:@"YourAppName.sqlite"];
