title: How to display an UIImage in Swift
body: <p>I simply would like to display an image which is part of the app.
  When executing the following code, my image is <code>nil</code>.</p>
  
  <pre><code>let image = UIImage(named: "back.png");
  </code></pre>
  
  <p>The "back.png" is stored in my <code>"Images.xcassets"</code> folder of my project.</p>
  
  <p>How to load the image from within the app folders?</p>
  
  <p>(Loading the Image from a path is working for me, but I do not know how to reference an image stored in the project itself)</p>
