Pull to Refresh for new items in Swift

I am trying to implement a pull to refresh functionality in a ViewController which contains a TableView. Currently, the TableView is displaying stories from a data source which contains the following stories [A, B, C, D]

When I pull to refresh, I get three new stories from server : [D, E, F] now I have to display the stories in this order [D, E, F, A, B, C]

override func viewDidLoad() {      super.viewDidLoad()                let refreshControl = UIRefreshControl()      refreshControl.addTarget(self, action:  #selector(loadItems), for: .valueChanged)      self.refreshControl = refreshControl  }    @objc func loadItems() {      // confused here                tableView.reloadData()      refreshControl?.endRefreshing()  }    override func numberOfSections(in tableView: UITableView) -> Int {      return 1  }    override func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {      return alphabet.count  }      override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {      let cell = tableView.dequeueReusableCell(withIdentifier: "Cell", for: indexPath)      cell.textLabel?.text = alphabet[indexPath.row]      return cell  }
