iOS Swift UITableViewCell custom swipe action buttons example

To add custom actions to your table view's rows, implement the tableView(_:editActionsForRowAt:) method in your table view's delegate object. Users swipe horizontally in a table view to reveal the actions associated with a row. Each row-action object contains the text display, the action to perform, and any specific formatting to apply to that action. If you do not implement this method, the table view displays the standard accessory buttons when the user swipes the row.

    func tableView(_ tableView: UITableView, editActionsForRowAt indexPath: IndexPath)
        -> [UITableViewRowAction]? {
        
        let delete = UITableViewRowAction(style: .destructive, title: "Delete",
                                          handler: handleRowAction)
        let edit = UITableViewRowAction(style: .normal, title: "Edit",
                                        handler: handleRowAction)
        edit.backgroundColor = UIColor.blue
        let other = UITableViewRowAction(style: .normal, title: "Other",
                                         handler: handleRowAction)
        other.backgroundColor = UIColor.orange
        return [other, edit, delete]
        
    }
