Explanation / Answer

var mainVC:UIViewController? mainVC = MainViewController(nibName: "MainViewController", bundle:nil); let frame = UIScreen.mainScreen().bounds; window = UIWindow(frame: frame); window!.rootViewController = mainVC; window!.makeKeyAndVisible(); return true; func generateRandomNumber() -> String { var result:String = ""; for _ in 1...4 { var digit:Int = Int(arc4random_uniform(8) + 1); result += "(digit)"; } return result; } @IBOutlet weak var numbersLabel:UILabel?; @IBOutlet weak var scoreLabel:UILabel?; @IBOutlet weak var inputField:UITextField?; func updateScoreLabel() { if(scoreLabel != nil) { scoreLabel!.text = "Score: (score)"; } } func setRandomNumberLabel() { if(numbersLabel != nil) { numbersLabel!.text = generateRandomNumber(); } } var score:Int = 0; super.viewDidLoad(); setRandomNumberLabel(); updateScoreLabel(); if(inputField != nil) { inputField!.font = UIFont(name: "Helvetica", size: 72.0); inputField!.frame.size.height = 100.0; inputField!.addTarget(self, action: "textFieldDidChange:", forControlEvents:UIControlEvents.EditingChanged); } func textFieldDidChange(textView:UITextView!) { if(inputField == nil || numbersLabel == nil || inputField!.text.utf16Count < 4 || numbersLabel!.text!.utf16Count < 4) { return; } var numbers:Int? = numbersLabel!.text!.toInt(); var input:Int? = inputField!.text.toInt(); if(numbers != nil && input != nil) { println("Comparing: (inputField!.text) minus (numbersLabel!.text!) == (input! - numbers!)"); if(input! - numbers! == 1111) { println("Correct!"); score++; } else { println("Incorrect!"); score--; } } setRandomNumberLabel(); updateScoreLabel(); inputField!.text = ""; }
