title: Accessing swift array inside a swift dictionary
body: <p>I have a function is that takes a dictionary, and I need to parse the information inside.</p>
  
  <p>I can get an NSArray out of the dictionary, but shouldn't I be able to access a native swift array?</p>
  
  <pre><code>class func parseResults(resultsDict:Dictionary&lt;String, AnyObject&gt;) -&gt; Array&lt;Track&gt;? {
  
          var results : NSArray = resultsDict["results"] as NSArray // This works
          //var results : Array = resultsDict["results"] as Array&lt;AnyObject&gt; // This doesnt work
  
          ...
      }
  </code></pre>
