title: How do I get the error message in Swift 2.0?
body: <p>I used this method very much in Swift 1.2: <code>NSURLConnection.sendSynchronousRequest(:_:_:_)</code> but this is apparently deprecated in iOS9. It still works however but now it uses the new Swift 2.0 Error Handling and I don't know how I will get the error message if it fails, ex. if time runs out.</p>
  
  <p>I know I have to put it into a do-catch and then say try before the metho but I dont know how to catch the error message.</p>
  
  <pre><code>do {
      let data = try NSURLConnection.sendSynchronousRequest(request, returningResponse: nil)
      return data 
  }
  catch _ {
      return nil
  }
  </code></pre>
  
  <p>Before I used NSError and then its description property, but now I have no clue.</p>
