exception thrown on Algorhythm swift app.

I am getting the following exception when I tried to add the additional playlistImageViews on the Algorhythm swift app:

Algorhythm[627:13770] *** Terminating app due to uncaught exception 'NSUnknownKeyException', reason: '[<Algorhythm.PlaylistMasterViewController 0x7fb6bb422900> setValue:forUndefinedKey:]: this class is not key value coding-compliant for the key playlistImageView.'

I tried setting break points, and it throws the exception on the following line: 

@IBOutlet weak var playlistImageView0: UIImageView!

I removed all the connections and rebuild them and I double/ triple checked that I hadn't misspelled anything, but now I'm stumped. Any help?
