title: Print data from Alamofire request, swift
body: <p>I made this request: </p>
  
  <pre><code>func AlamofireGetCode()
  {
      let username: String = searchTextField.text!
      var url:String!
      url = "https:// ... "
  
      AF.request(url, method: .get, encoding: JSONEncoding.default)
          .responseJSON { response in
              switch response.result {
              case .success:
                  debugPrint(response)
              case .failure(let error):
                  fatalError("\(error)")
              }
          }
  }
  </code></pre>
  
  <p>And I'm getting this response with different fields:</p>
  
  <pre><code>[Result]: success({
  "incomplete_results" = 0;
  items =     (
              {
          "username" = " ... "
          ...
  </code></pre>
  
  <p>How do I get some specific field like "username" in Swift? 
  I would like to have all the username of all the user and store them, could you help me? </p>
