title: Loading image to Image Cell from URL
body: <p>I'm learning to code in swift.
  I'm trying to load an image onto an image cell located within an image well.I'm using the following code </p>
  
  <pre><code>import Cocoa
  
  class ViewController: NSViewController {
  
      @IBOutlet weak var well: NSImageCell!
      @IBAction func clickme(_ sender: Any) {
      let image = NSImage(byReferencing:NSURL(string: "http://imgsv.imaging.nikon.com/lineup/lens/zoom/normalzoom/af-s_dx_18-140mmf_35-56g_ed_vr/img/sample/sample1_l.jpg")! as URL)
          well.image=image;
      }
  
      override func viewDidLoad() {
          super.viewDidLoad()
  
          // Do any additional setup after loading the view.
      }
  
      override var representedObject: Any? {
          didSet {
          // Update the view, if already loaded.
          }
      }
  
  
  }
  </code></pre>
  
  <p>No exception is thrown nor any image is loaded.
  What I'm I doing wrong?</p>
