Section 29.10 - Handling TableView Swipe Gestures

The code in this section can crash due to the a missing call to the reloadData() method of the tableview instance. The code should read as follows:

override func tableView(_ tableView: UITableView,
          trailingSwipeActionsConfigurationForRowAt indexPath: IndexPath) ->
    UISwipeActionsConfiguration? {
        let configuration = UISwipeActionsConfiguration(actions: [
            UIContextualAction(style: .destructive, title: "Delete",
                               handler: { (action, view, completionHandler) in
                                let row = indexPath.row
                                self.attractionNames.remove(at: row)
                                self.attractionImages.remove(at: row)
                                self.webAddresses.remove(at: row)
        return configuration
