body: <p>how to show or hide a image in Swift by taping on a Button?
  For example:</p>
  
  <p>i have ImageA and ImageB and one Button which i want to use to move ImageA to ImageB and back to ImageA and so on..</p>

  <p>My code is: </p>
  
  <pre><code>import UIKit
  
  class ViewController: UIViewController {
  
  @IBOutlet weak var Bild1: UIImageView!
  @IBOutlet weak var Bild2: UIImageView!
  
  @IBAction func pressedButton(sender: AnyObject) {
  
      Bild1.hidden = true
      Bild2.hidden = false
  }
  
  
  override func viewDidLoad() {
      super.viewDidLoad()
  
      Bild1.hidden = false
      Bild2.hidden = true
  
      // Do any additional setup after loading the view, typically from a nib.
  }
  
  override func didReceiveMemoryWarning() {
      super.didReceiveMemoryWarning()
      // Dispose of any resources that can be recreated.
  }
  
  
  }
  </code></pre>
