Function "find" did n't work in Xcode 7

After a lessons about Playlists I tried to run this app on my device on a beta version of Xcode 7, but it crash ("find" is unavailable: call the "IndexOf()" method of the collection) Here is a part of code:

let playlistImageView = sender!.view as! UIImageView
if let index = find(playlistsArray, playlistImageView){

    playlistDetailController.playlist = Playlist(index: index)}
