title: Is there any advantage at all in Swift if redundant code?
body: <pre><code>var _name = item["name"] as NSString
  </code></pre>
  
  <p>VS</p>
  
  <pre><code>var _name: NSString = item["name"] as NSString
  </code></pre>
  
  <p>Is there any advantage in speed or something behind the scenes in adding the extra : NSString besides readability? If not, why keep it at all?</p>
