catch{
print(error)
}
}

extension TasksListsViewController: UITableViewDelegate{ func tableView(_ tableView: UITableView, editActionsForRowAt indexPath: IndexPath) -> [UITableViewRowAction]? { let deleteAction = UITableViewRowAction(style: .destructive, title: "Delete", handler: { (deleteAction, indexPath) in let tasksListsManager = TasksListManager() let listToBeDeleted = self.tasksLists[indexPath.row] ...
