 You'll need to provide the navigation controller with a delegate. You'll also need to set the animation up when the table view cell -> detail view segue is triggered.
 
 1. In your table view controller's `viewDidLoad()`, set the `navigationController`'s delegate to an instance of `NavigationControllerDelegate`.

 3. In your `NavigationControllerDelegate`'s `navigationController(_ navigationController:, animationControllerFor:, from:, to:)` method, create and configure an `Animator` object, and return it. The animator will need to have its source and destination imageView and label properties set. **Note: You must keep a strong reference to the animator object in your navigation controller delegate. Use a property to hold it instead of creating a temporary instance and referencing it solely in this method.**
 
 ## Part Three - Implement the Animation

 If you finish early or want to push yourself, here are a few additional features you can implement:
 
 - Make it so the back action can be perform using a swipe guesture like a standard navigation controller. The animation should be interactive and should track the user's finger. Hint: You'll need to use a `UIPanGuestureRecognizer`.
