title: SwiftyJSON YouTube API
body: <p>I am using SwiftyJSON to retrieve data from the youtube api.
  I am writing swift 4 code.</p>
  
  <p>I'm trying to print out the description</p>
  
  <p>Here is what I have:</p>
  
  <pre><code>func getFeedVideos() {
      Alamofire.request(API_URL, method: .get, parameters: ["part":"snippet", "playlistId":PLAYLIST_ID,"key":API_KEY], encoding: URLEncoding.default, headers: nil).responseJSON { (response) in
  
          if let value = response.result.value {
              let json = JSON(value)
  
              print(json["items"]["snippet"]["description"].stringValue)
          }
  
      }
  }
  </code></pre>
  
  <p>But no description is being printed out.</p>
  
  <p>Below is the youtube API:</p>
  
  <pre><code>  "items" : [
      {
        "kind": "youtube#playlistItem",
        "etag": etag,
        "id": string,
        "snippet": {
          "publishedAt": datetime,
          "channelId": string,
          "title": string,
          "description": string,
          "thumbnails": {
            (key): {
              "url": string,
              "width": unsigned integer,
              "height": unsigned integer
            }
          },
          "channelTitle": string,
          "playlistId": string,
          "position": unsigned integer,
          "resourceId": {
            "kind": string,
            "videoId": string,
          }
        },
      }
  </code></pre>
