title: Get Facebook profile picture from URL
body: <p>I want to upload the profile picture from Facebook to Firebase. I tried this answer: <a href="https://stackoverflow.com/questions/39007364/upload-facebook-image-url-to-firebase-storage">Upload Facebook image URL to Firebase Storage</a> 
  However, Swift is giving me errors on the third line of code of that answer. The code is:</p>
  
  <pre><code>let dictionary = result as? NSDictionary
  let data = dictionary?.object(forKey: "data")
  let urlPic = (data?.objectForKey("url"))! as! String
  </code></pre>
  
  <p>Swift is telling me: Cannot call value of non-function type 'Any?!' after I changed the code to what Swift keeps suggesting me:</p>
  
  <pre><code>let urlPic = ((data as AnyObject).object(ForKey: "url"))! as! String
  </code></pre>
  
  <p>What is the code to use when I want to retrieve the profile picture from Facebook? My goal is to also store it into Firebase, but that will come after I get the profile picture first.</p>
