Core Data app failed to launch in time

I have an app that creates a persistent store in application:didFinishLaunchingWithOptions. Adding the store can apparently take too long, which causes iOS to terminate the app before it finishes launching. How to add the store to the coordinator off the main thread? Any examples? stackoverflow link

OS Version: iOS 6.1.3 (10B329) Report Version: 104

NSFileManager *fileManager = [NSFileManager defaultManager];

_persistentStoreCoordinator = [[NSPersistentStoreCoordinator alloc] initWithManagedObjectModel:[self managedObjectModel]];

    NSLog(@"Unresolved error %@, %@", error, [error userInfo]);
    abort();
}

return _persistentStoreCoordinator;

as general advice you should not create nothing heavy in the applicationDidFinishLaunching method. The Core data Persistent Store isn't heavy to create, but in the feature could be, due to migration process. To be sure that is the persistent store and not something else, try to comment out that part of code. Are you initializing the store with data?
