Swift 2 - Sigabrt错误

Question

我正在为游戏创建倒数计时器，但我收到了SIGABRT错误。我在Swift 2编码。它从45秒倒计时，然后有两个其他标签，一个是5秒钟少，另一个少10秒钟。该应用程序在模拟器中成功打开。一旦我点击屏幕就会崩溃。我尝试删除故事板上按钮/标签与ViewController.swift之间的所有关系。然后，我重新“附加”它们。该按钮没有文字，并且高于一切。因此，无论您在屏幕上点按哪个位置，它都会启动或重置。点击按钮后，NSTimer启动。一旦再次点击该按钮，它将重置定时器，以便下次准备就绪。

    var Timer = NSTimer(); 

    var Toggle = false; 

    func Countdown(){ 
     //Time Left Before Bomb Explodes 
     TimerCount = 45; 
     TimerCount -= 1 
     if(TimerCount <= 0){ 
      MainTime.text = "No Time" 
     }else{ 
      MainTime.text = "\(TimerCount)" 
      Main = TimerCount 
     }

     Kit = Main - 5

     }else{

      NoDiffuseKit.text = "No Time" 
     }else{ 
      NoDiffuseKit.text = "\(NoKit)" 
     } 
    } 

    @IBAction func ToggleButton(sender: AnyObject) { 
     //If The Button Is At Its Default at 45 Seconds & Not Running 
     if(Toggle == false){ 
      if TimerRunning == false{ 
       Timer = NSTimer.scheduledTimerWithTimeInterval(1, target: self, selector: Selector("Counting"), userInfo: nil, repeats: true) 
       TimerRunning = true; 
       Toggle = true; 
      } 
     //If Timer is Running & Needs To Be Stopped 
     }else if (Toggle == true){ 
      if TimerRunning == true{ 
       Timer.invalidate() 
       TimerRunning = false 
       TimerCount = 45; 
       MainTime.text = "45" 
       Toggle = false; 
      } 
     } 
    } 



    override func viewDidLoad() { 
     super.viewDidLoad() 
     // Do any additional setup after loading the view, typically from a nib. 

    } 

    override func didReceiveMemoryWarning() {
