title: Accessing JSON data from AFNetworking using Swift
body: <p>I have access a Yahoo Finance data set with the link in the code.  It executes and prints the JSON data in the debug window.  How would I store and then print selected fields in myNameLabel.  For example the "symbol" or "LastTradePriceOnly" fields?</p>
  
  <pre><code>class ViewController: UIViewController {
  
  
      @IBOutlet weak var myNameLabel: UILabel!
  
      override func viewDidLoad() {
          super.viewDidLoad()
          // Do any additional setup after loading the view, typically from a nib.
          let manager = AFHTTPRequestOperationManager()
  
          manager.GET( "https://query.yahooapis.com/v1/public/yql?q=select%20*%20from%20yahoo.finance.quote%20where%20symbol%20in%20(%22AAPL%22)&amp;format=json&amp;diagnostics=true&amp;env=store%3A%2F%2Fdatatables.org%2Falltableswithkeys&amp;callback=",
              parameters: nil,
              success: { (operation: AFHTTPRequestOperation!,responseObject: AnyObject!) in
                  println("JSON: " + responseObject.description)
  
                  //How to access and print individual fields?
  
              },
              failure: { (operation: AFHTTPRequestOperation!,error: NSError!) in
                  println("Error: " + error.localizedDescription)
              })
      }
  
      override func didReceiveMemoryWarning() {
          super.didReceiveMemoryWarning()
          // Dispose of any resources that can be recreated.
      }
  
  
  }
