extension ViewController: UITableViewDelegate {
  func tableView(_ tableView: UITableView, trailingSwipeActionsConfigurationForRowAt indexPath: IndexPath) -> UISwipeActionsConfiguration? {
    let askAction = UIContextualAction(style: .normal, title: nil) { action, view, complete in
      print("Ask!")
      complete(true)
    }

    // here set your image and background color
    askAction.image = IMAGE
    askAction.backgroundColor = .darkGray

    let blockAction = UIContextualAction(style: .destructive, title: "Block") { action, view, complete in
      print("Block")
      complete(true)
    }

    return UISwipeActionsConfiguration(actions: [blockAction, askAction])
  }

  func tableView(_ tableView: UITableView, willDisplay cell: UITableViewCell, forRowAt indexPath: IndexPath) {
    cell.textLabel?.text = "row: \(indexPath.row)"
  }
}
