尝试以下方法：

func tableView(_ tableView: UITableView, trailingSwipeActionsConfigurationForRowAt indexPath: IndexPath) -> UISwipeActionsConfiguration? {
        let item = UIContextualAction(style: .destructive, title: "Delete") {  (contextualAction, view, boolValue) in
            //Write your code in here
        }
        item.image = UIImage(named: "deleteIcon")

        let swipeActions = UISwipeActionsConfiguration(actions: [item])
    
        return swipeActions
    }

字符串

func tableView(_ tableView: UITableView, editActionsForRowAt indexPath: IndexPath) -> [UITableViewRowAction]? {
    let delete = UITableViewRowAction(style: .destructive, title: "Delete") { (action, indexPath) in
        // delete item at indexPath
    }

    let share = UITableViewRowAction(style: .normal, title: "Disable") { (action, indexPath) in
        // share item at indexPath
    }

    share.backgroundColor = UIColor.blue

    return [delete, share]
}

字符串
请注意，第一个按钮使用.destructive样式，因此默认情况下它将被着色为红色，但第二个按钮被指定为蓝色。
