Being able to persist a single Podcast in our program is nice, but we really need to save a list of podcasts instead. In today's lesson, we discuss how to easily go from saving a single Podcast to saving an array such as [Podcast]. Once done with this implementation, we render out our favorited podcasts in our FavoritesController collection view. Finally the last task is to show how we can delete a podcast by using a UILongPressGestureRecognizer. Enjoy.
