title: NSURLConnection throws after updating to Swift 2.0
body: <p>Before the Swift 2.0 Update this code worked perfectly to download my JSON File from the Server with a PHP Script:</p>
  
  <pre><code>let url = NSURL(string: webAdress)
  let cachePolicy = NSURLRequestCachePolicy.ReloadIgnoringLocalAndRemoteCacheData
  var request = NSMutableURLRequest(URL: url!, cachePolicy: cachePolicy, timeoutInterval: 5.0)
  
  var response: NSURLResponse? = nil
  var error: NSError? = nil
  let reply = NSURLConnection.sendSynchronousRequest(request, returningResponse:&amp;response, error:&amp;error)
  </code></pre>
  
  <p>After the Update Xcode asked me to do some changes. I did and the code had no Error, but it always throws...</p>
  
  <pre><code>    let url = NSURL(string: webAdress)
      let cachePolicy = NSURLRequestCachePolicy.ReloadIgnoringLocalAndRemoteCacheData
      let request = NSMutableURLRequest(URL: url!, cachePolicy: cachePolicy, timeoutInterval: 5.0)
  
      var response: NSURLResponse? = nil
      var reply = NSData()
      do {
      reply = try NSURLConnection.sendSynchronousRequest(request, returningResponse:&amp;response)
      } catch {
          print("ERROR")
      }
  </code></pre>
  
  <p>Looking forward to your solutions!</p>
