Fatal error: Index out of range: file Swift/ContiguousArrayBuffer.swift

I have modified the code, by adding an action to perform a segue to the "Main Menu" apart from "Try again" button after the game is over. But, when the player exits the game View controller and clicks on some other view controller, the app crashes. It gives the following error:-

Fatal error: Index out of range: file Swift/ContiguousArrayBuffer.swift

This is the only change that I have done:-

func displayGameOverAlert() {
      let (title, message) = getGameOverTitleAndMessage()
      let alert = UIAlertController(title: "Game Over", message: message, preferredStyle: .alert)
      let action = UIAlertAction(title: title, style: .default,
                             handler: { _ in
                              self.prepareGame()
           }
      )
      let action_2 = UIAlertAction(title: "Main Menu", style: .default, handler: { _ in
                                    self.performSegue(withIdentifier: "2to1segue", sender: self)})
      alert.addAction(action)
      alert.addAction(action_2)
      self.present(alert, animated: true, completion: nil)
    }

Hey, looking at the code, I don't know what causes the problem, probably inside the destination view controller. What ViewController the segue 2to1segue goes to?

Regarding your question, "What ViewController the segue 2to1segue goes to?" The view controller is an empty view controller. I think it is something to do with "func touchesBegan" as after the game ends, and I perform a segue to some other view controller, it is still recognizing my tap on the screen and crashing by giving the above-mentioned error!
