swift - SwiftUI - Custom Swipe Actions In List

Question

How can I use custom Swipe Actions in SwiftUI?

I tried to use the UIKit Framework to get these working in SwiftUI. But that doesn't work for me.

import SwiftUI
import UIKit



    init() {
        override func tableView(_ tableView: UITableView, trailingSwipeActionsConfigurationForRowAt indexPath: IndexPath) -> UISwipeActionsConfiguration? {
            let important = importantAction(at: indexPath)
            return UISwipeActionsConfiguration(actions: [important])
        }
        func importantAction(at indexPath: IndexPath) -> UIContextualAction {
            let action = UIContextualAction(style: .normal, title: "Important") { (action, view, completion) in
                print("HI")
            }
            action.backgroundColor = UIColor(hue: 0.0861, saturation: 0.76, brightness: 0.94, alpha: 1.0) /* #f19938 */
            action.image = UIImage(named: "pencil")
            return action
        }
    }






struct TestView: View {

      NavigationView {
               List {
                    ForEach(appointmentsViewModel.appointments.identified(by: .id)) { appointment in Row_Appointments(appointment: appointment)
                }.onDelete(perform: delete)
            }
        }
    }
}

If your deployment target is iOS 15 (or newer), then you can use the swipeActions modifier to customize the swipe actions of a list item.

This also applies to watchOS 8 and macOS 12.

These operating systems will be released in late 2021.

Prior to the late 2021 version of SwiftUI, there is no support for custom swipe actions for List items.

If you need to target an older version, you would probably be better off implementing a different user interface, like adding a toggle button as a subview of your list item, or adding a context menu to your list item.
