You can add the UISwipeGestureRecognizer to your TableViewCell to do it.

For example

let swipeToDeleteGesture = UISwipeGestureRecognizer(target: self, action: #selector(deleteCellWithoutConfirm(gesture:)))
swipeToDeleteGesture.direction = .left
your_cell.addGestureRecognizer(swipeToDeleteGesture)

and process the delete function

@objc func deleteCellWithoutConfirm(gesture: UIGestureRecognizer) {
    guard let cell = gesture.view as? UITableViewCell,
        let indexPath = tableView.indexPath(for: cell) else {
        return
    }
    // delete your data first, then reload tableView
    your_data.remove(at: indexPath.row)
    tableView.reloadSections(IndexSet(integer: 0), with: UITableViewRowAnimation.fade)
}
