I get an error when typing "if let index = find(playlistsArray, playlistImageView)" It says "'find' is unavailable: call the 'indexOf() method on the collection'" What does this mean?

Try the following code.
let playlistImageView = sender!.view as! UIImageView
if let index = playlistsArray.indexOf(playlistImageView) {}
Don't forget to force unwrap where required using the ! characters in the let statement before the if. Don't be frightened, the if let will make sure all is well. ;)
