title: AlamoFire: How can get responseJSON values
body: <p>Currently I'm using the new Swift Library Called AlamoFire and I want to get the JSON Response on a NSDictionary or make use of it on the app.</p>
  
  <pre><code>// Pasar Parametros al API
      let parameters = ["username": usuario.text,
          "password": contrasena.text,
          "type": "login_clients"]
  
      // Iniciar el POST request y esperar los datos y parsearlos
      Alamofire.request(.POST, "http://mycoolapi.com", parameters: parameters).responseJSON {
  
          (request, response, JSON, error) in
  
          // Imprimir JSON (response)
          var respuesta = JSON
          let transaccion = respuesta["transaction"]
          NSLog("Response: %@", transaccion)
  
  
  
          self.performSegueWithIdentifier("mostrar_menu", sender: self)
  
  
      }
  </code></pre>
  
  <p>The following is not working, Any idea what Im doing wrong?</p>
