       do { 

        let jsonResult = try JSONSerialization.jsonObject(with: blogContent, options: JSONSerialization.ReadingOptions.mutableContainers)

         if let item = items["posts"] as? NSArray { 

          for posts in item { 

           if let post = posts as? [String: AnyObject] { 

            print(post["title"]!)
