I am having trouble... I was doing fine and all of a sudden this pops up with an error. "First Game[1895:70b] *** Terminating app due to uncaught exception 'NSUnknownKeyException', reason: '[<ViewController 0x8a526f0> setValue:forUndefinedKey:]: this class is not key value coding-compliant for the key predictions.'"
