title: Assign MPMediaItemArtwork to UIImage
body: <p>I have a table view, where i display my songs via MPMedia. What i want is, that the album cover for each song gets displayed in the cell, too. I tried it the same way i did with song and artist: </p>
  
  <p><code>cell?.textLabel?.text = items.title
   cell?.detailTextLabel?.text = items.artist
   cell?.imageView?.image = items.artwork</code></p>
  
  <p>but I get the error "Cannot assign value of type MPMediaItemArtwork? to type UIImage?"</p>
  
  <p>Anyone know how to do this? If you need more code just let me know.</p>
