How To Use UIScrollView In Swift:- => ViewController.swift file and add the following properties:- var imageView: UIImageView! var scrollView: UIScrollView! override func viewDidLoad() {       super.viewDidLoad()   // 1     imageView = UIImageView(image: UIImage(named: "strandvagen.jpg"))      // 2   scrollView = UIScrollView(frame: view.bounds)   scrollView.backgroundColor = UIColor.blackColor()   // 3   scrollView.contentSize = imageView.bounds.size   // 4        scrollView.addSubview(imageView)   view.addSubview(scrollView) } class ViewController: UIViewController, UIScrollViewDelegate { @IBOutlet var scrollView: UIScrollView! var imageView: UIImageView! override func viewDidLoad() {   super.viewDidLoad()   // 1   let image = UIImage(named: "photo1.png")!   imageView = UIImageView(image: image)   imageView.frame = CGRect(origin: CGPoint(x: 0, y: 0), size:image.size)   scrollView.addSubview(imageView)   // 2   scrollView.conte
