title: Show image in UIImageview by using alamofireimage
body: <p>It seems to be a silly question, but I'm pretty new with Swift.</p>
  
  <p>I want to download PNG image from <a href="https://httpbin.org/image/png" rel="nofollow noreferrer">https://httpbin.org/image/png</a> and make it show in my <code>UIImageView</code> which has the name <code>imageView</code>, but it's not working. </p>
