title: UIScrollView not scrolling in Swift
body: <p>My UIScrollView won't scroll down. I don't know why. I already followed Apple documentation regarding to this issue.</p>

      override func viewDidLoad() {
      super.viewDidLoad()
  
      // Do any additional setup after loading the view.
  
  }
  
  override func viewDidLayoutSubviews() {
      scroller.scrollEnabled = true
      // Do any additional setup after loading the view
      scroller.contentSize = CGSizeMake(400, 2300)
  }
  </code></pre>
