Adding swipe left on tableView cell with custom background color

In tableView, we can add swipe left or right to let user perform an action based on selected cell.

first we need to setup tableView delegate to the parent viewController then set this function:

 func tableView(_ tableView: UITableView, trailingSwipeActionsConfigurationForRowAt indexPath: IndexPath) -> UISwipeActionsConfiguration? {
        let amendAction = UIContextualAction(
            style: .normal,
            title: "Save",
            handler: { [weak self] _, _, _ in
                self?.handleAmendAction()
            }
        )
        amendAction.backgroundColor = UIColor.green
        
        let withdrawAction = UIContextualAction(
            style: .normal,
            title: "Delete",
            handler: { [weak self] _, _, _ in
                self?.handleWithdrawAction()
            }
        )
        withdrawAction.backgroundColor = UIColor.delete
        
        return UISwipeActionsConfiguration(actions: [withdrawAction, amendAction])
    }
