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)
            }
        }
    }
}

UPDATE

As far as I can tell, the situation has not improved as of Xcode 12 beta 1 (released at WWDC 2020).

ORIGINAL

As of Xcode 11.3.1, SwiftUI doesn't support custom swipe actions for List items. Based on the history of Apple’s SDK evolution, we’re not likely to see support until the next major SDK version (at WWDC 2020) or later.

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.
