title: Swift Errors Thrown from here are not handled
body: <p>I have had my code working in Xcode 6 but since I got Xcode 7 I cannot figure out how to fix this. The let jsonresult line has an error that says Error thrown from here are not handled. Code is below:</p>
  
  <pre><code>func connectionDidFinishLoading(connection: NSURLConnection!) {
  
      let jsonresult:NSDictionary = try NSJSONSerialization.JSONObjectWithData(self.bytes, options: NSJSONReadingOptions.MutableContainers) as! NSDictionary
  
      print(jsonresult)
  
      let number:Int = jsonresult["count"] as! Int
  
      print(number)
  
      numberElements = number
  
      let results: NSDictionary = jsonresult["results"] as! NSDictionary
  
      let collection1: NSArray = results["collection1"] as! NSArray
  </code></pre>
  
  <p>Thanks</p>
