UITableViewDelegate method for swipe actions is not called at iOS 13-CodePudding

I use a tableView(_:trailingSwipeActionsConfigurationForRowAt:) method in order to add swipe-to-delete gesture in iOS app. It works as expected at iOS 16.2 simulator. But in iOS 13.7 simulator it does not show any actions on swipe.

The method is:

func tableView(_ tableView: UITableView, trailingSwipeActionsConfigurationForRowAt indexPath: IndexPath) -> UISwipeActionsConfiguration? {
        let deleteAction = UIContextualAction(style: .destructive, title: "Delete") { [weak self] action, view, handler in
            self?.presenter.requestDeletion(at: indexPath.row)
        }
        
        let config = UISwipeActionsConfiguration(actions: [deleteAction])
        return config
    }

I've set breakpoints inside the method and they are not even called on swipe. Swipes at iOS 16.2 trigger the breakpoints.

CodePudding user response：

It's necessary to return true from the tableView(_:canEditRowAt:) data source method, and swipe actions work as expected.
