Swift Realm: can you observe when a Results object changes?

When a Results object is returned from a query it is dynamic. So, if you query for all Dog objects, and then you create a new Dog, your Results will include that new Dog. Is there anyway to track when/what index gets changed in the Results object? Looking through their documentation, the only tool I see would be Realm NotificationTokens. But notifications aren't a great solution for table views, as your only option is to reload the whole data set. I'm looking for something closer to NSFetchedResultsController.

Sadly not yet. At present, the notification token is the only way you can receive events for when the data in a Realm file is changed (No matter what it is.)

That being said, fine-grain notifications (The ability to register for events in where specific changes occur) is on the Realm roadmap, and should be coming in a future release soon.

For the time being, if you want to track when a new Dog property is created, you can always use the NSNotification system to manually fire off an app-wide event notifying interested objects in the changes.
