title: How I can parse JSON file without keys?
body: <p>I have downloaded JSON file from this url: <a href="https://raw.githubusercontent.com/David-Haim/CountriesToCitiesJSON/master/countriesToCities.json" rel="nofollow noreferrer">https://raw.githubusercontent.com/David-Haim/CountriesToCitiesJSON/master/countriesToCities.json</a></p>
  
  <p>I got stuck after I parse all JSON file into <code>let json</code></p>
  
  <pre><code> let requestURL: NSURL = NSURL(string: "https://raw.githubusercontent.com/David-Haim/CountriesToCitiesJSON/master/countriesToCities.json")!
      let urlRequest: NSMutableURLRequest = NSMutableURLRequest(URL: requestURL)
      let session = NSURLSession.sharedSession()
      let task = session.dataTaskWithRequest(urlRequest) {
          (data, response, error) -&gt; Void in
  
          let httpResponse = response as! NSHTTPURLResponse
          let statusCode = httpResponse.statusCode
  
          if (statusCode == 200) {
  
              do{
  
                  let json = try NSJSONSerialization.JSONObjectWithData(data!, options:.AllowFragments)
  
                  print (json)
              }catch {
                  print("Error with Json: \(error)")
              }
  
          }
      }
  
      task.resume()
  
  }
  </code></pre>
