Arrrggg... Getting a SIGABRT from AppDelegate.swift file

After adding in the Stepper code the compile is successful but it crashes with the following error from AppDelegate file: Terminating app due to uncaught exception 'NSUnknownKeyException', reason: '[<VendingMachine.ViewController 0x7ff301616af0> setValue:forUndefinedKey:]: this class is not key value coding-compliant for the key updateQuantity.'

My code: @IBAction func updateQuantity(sender: UIStepper) { }

Still get the error even after I comment out the code.
