        for obj in touches {
            if let touch = obj as? UITouch {
                let view = self.touchToView[touch]

                self.handleControl(view, controlEvent: .TouchCancel)

You need to unwrap the optional - try 

for obj in touches! {
   // code here
}

  • I have another small mistake ... I can upload it here or simply register a new question?? – Swift2 Jul 06 '15 at 16:41
  • Probably best to open a new question. Protip - you can paste your whole code in spoilers into the question box to put the code inline :) – Mark Jul 06 '15 at 16:45
