title: Xcode swift 3 don't know how to display an image where I click
body: <p>I am a new programmer and I ran into a problem. I want an image to appear on the screen where I click. So for example I click on the top of the screen I want the image to show there and then if I click on the bottom of the screen I want the image to go there, but I don't want the first image to disappear I just want to add another one. Using swift 3 
  Thanks </p>
