코드와 간략한 설명

  func tableView(_ tableView: UITableView, trailingSwipeActionsConfigurationForRowAt indexPath: IndexPath) -> UISwipeActionsConfiguration? {

        let deleteAction = UIContextualAction(style: .destructive, title: "削除") { _,_,_  in

            self.cellContentsArray.remove(at: indexPath.row)
            self.tableView.deleteRows(at: [indexPath as IndexPath], with: .automatic)
            self.tableView.reloadData()

        }

        let cellPlus = UIContextualAction(style: .normal, title: "") { _, _, _ in

            self.cellContentsArray.insert(String(Int(self.cellContentsArray[indexPath.row])! + 1), at: indexPath.row + 1)
            self.tableView.reloadData()

        }
        cellPlus.image = UIImage(systemName: "plus.bubble")
        cellPlus.backgroundColor = .systemGreen

        return UISwipeActionsConfiguration(actions: [deleteAction,cellPlus])
    }

모든 코드

import UIKit

class ViewController: UIViewController {


    @IBOutlet weak var tableView: UITableView!

    lazy var cellContentsArray = ["1","2","3","4","5","6","7","8","9","10"]

    }
}

extension ViewController:UITableViewDelegate,UITableViewDataSource{


    func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {

        return cellContentsArray.count

    }

    func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {

        let cell = tableView.dequeueReusableCell(withIdentifier: "Cell", for: indexPath)
