Why do we have to create a helper method?

Why can't we do this in the init method?

backgroundColor = playlistDictionary["backgroundColor"] as UIColor!

If I remember correctly I think he is having you create a method because the background color will change depending on which playlist the user selects.

playlistDictionary["backgroundColor"] does not return a color, but rather a dictionary with rgb-values. So you need to instantiate a UIColor from those values. That said, there is absolutely no reason for putting this in a "helper method", since (for now) it is only being called once to set the background in the initialiser ... well, except for learning to separate your code into reusable parts :)
