title: Read response from Facebook Graph Request in Swift 4
body: <p>I'm trying to add a Facebook friend list to my Swift iOS app using the Graph API.</p>
  
  <p>I'm struggling to work out how to actually access the data that's being send back from Facebook.</p>
  
  <p>The response I get looks like this:</p>
  
  <pre><code>success(FacebookCore.GraphResponse(rawResponse: Optional({
  "first_name" = Jamie;
  id = 1626917907360895;
  "last_name" = McAllister;
  name = "Jamie McAllister";
  picture =     {
      data =         {
          height = 50;
          "is_silhouette" = 0;
          url = "https://scontent.xx.fbcdn.net/v/t1.0-1/p50x50/12994335_1101318013254223_4481895970110564364_n.jpg?oh=d10209f113213981e4417e7f6f3f82d8&amp;oe=5A91F135";
          width = 50;
      };
  };
  })))
  </code></pre>
  
  <p>My graph Request is just <code>/me</code> for now as I'm the only registered user. But all the fields in the response are what I will be requesting from the friends list</p>
  
  <p>The graph request looks like this:</p>
  
  <pre><code>var graph = GraphRequest.init(graphPath: "me")
      graph.parameters = ["fields": "id, first_name, last_name, middle_name, name, email, picture"]
  
      graph.start({ (response, data) in
          print("======GRAPH=====")
          print(data)
  
          })
  </code></pre>
  
  <p>So, I want to be able to take the <code>GraphResponse</code>, make it an Array and assign it to a variable. I am completely stumped by this one.</p>
