title: Save Alamofire Result as Variable?
body: <p>I've been trying to find out how to save a part of a JSON response from Alamofire as a variable to make an if statement and can't seem to find how to do it.</p>
  
  <p>I made a piece of code to use as an example for the question which consists of the following:</p>
  
  <pre><code>import UIKit
  import Alamofire
  
  class ViewController: UIViewController {
  
      override func viewDidLoad() {
          super.viewDidLoad()
  
  
          Alamofire.request("http://api.openweathermap.org/data/2.5/weather?q=London,uk&amp;appid=44143256ee15e9c3f521ca062463dd8d").responseJSON { response in
              print(response.result)   // result of response serialization
  
              if let JSON = response.result.value {
                  print("JSON: \(JSON)")
              }
          }  
      } 
  }
  </code></pre>
  
  <p>I get the following response from the API request:</p>
  
  <pre><code>JSON: {
  base = stations;
  clouds =     {
      all = 0;
  };
  cod = 200;
  coord =     {
      lat = "51.51";
      lon = "-0.13";
  };
  dt = 1485031800;
  id = 2643743;
  main =     {
      humidity = 83;
      pressure = 1026;
      temp = "270.54";
      "temp_max" = "273.15";
      "temp_min" = "267.15";
  };
  name = London;
  sys =     {
      country = GB;
      id = 5091;
      message = "0.0038";
      sunrise = 1484985141;
      sunset = 1485016345;
      type = 1;
  };
  visibility = 7000;
  weather =     (
              {
          description = haze;
          icon = 50n;
          id = 721;
          main = Haze;
      }
  );
  wind =     {
      speed = 1;
  };
  }
  </code></pre>
  
  <p>From this JSON response I would like to save the weather description so I could use the following statement:</p>
  
  <pre><code>if var currentWeather = sunny {
       return "Nice day!"
  } else {
       return "Uh-Oh, keep warm!"
  }
  </code></pre>
  
  <p>If anyone could help me with this I would greatly appreciate it! If I have to use SwiftyJSON to make it easier that's fine I've just been struggling with this for a while and need to figure it out!</p>
