How to Add Swipe Actions to List ? - SwiftUI - ios

Question

I want to add swipe actions to my list for show some actions.
All I want is add some actions for swipe left gesture on list row like mail application of ios.
I found this #michał-ziobro Swipe Actions Modifier solution but it is not working :/
Some parts of that code gave me errors and I fixed them with some extensions, I thought maybe that is the reason why it is not working.
struct TableViewConfigurator: UIViewControllerRepresentable {
var configure: (UITableView) -> Void = { _ in }
func makeUIViewController(context: UIViewControllerRepresentableContext<TableViewConfigurator>) -> UIViewController {
UIViewController()
}
func updateUIViewController(_ uiViewController: UIViewController, context: UIViewControllerRepresentableContext<TableViewConfigurator>) {
let tableViews = UIApplication.nonModalTopViewController()?.navigationController?.topViewController?.view.allSubViewsOf(type: UITableView.self) ?? [UITableView]()
for tableView in tableViews {
self.configure(tableView)
}
}
}
struct ListSwipeActions: ViewModifier {
#ObservedObject var coordinator = Coordinator()
func body(content: Content) -> some View {
return content
.background(TableViewConfigurator(configure: { tableView in
DispatchQueue.main.asyncAfter(deadline: .now() + 0.1) {
tableView.delegate = self.coordinator
}
}))
}
class Coordinator: NSObject, ObservableObject, UITableViewDelegate {
func scrollViewDidScroll(_ scrollView: UIScrollView) {
print("Scrolling ....!!!")
}
func tableView(_ tableView: UITableView, editingStyleForRowAt indexPath: IndexPath) -> UITableViewCell.EditingStyle {
return .delete
}
func tableView(_ tableView: UITableView, trailingSwipeActionsConfigurationForRowAt indexPath: IndexPath) -> UISwipeActionsConfiguration? {
let isArchived = false
let title = isArchived ? "Unarchive" : "Archive"
let archiveAction = UIContextualAction(style: .normal, title: title, handler: {
(action, view, completionHandler) in
// update data source
completionHandler(true)
})
archiveAction.title = title
archiveAction.image = UIImage(systemName: "archivebox")!
archiveAction.backgroundColor = .systemYellow
let configuration = UISwipeActionsConfiguration(actions: [archiveAction])
return configuration
}
}
}
extension List {
func swipeActions() -> some View {
return self.modifier(ListSwipeActions())
}
}
and here is my list view :
struct NotificationsTab: View {
#ObservedObject var viewModel = NotificationsVM()
func delete(at offsets: IndexSet) {
viewModel.notifications.remove(atOffsets: offsets)
}
var body: some View {
NavigationView {
Group{
if viewModel.notifications.count > 0 {
List{
ForEach(self.viewModel.notifications, id: \.id){ notification in
HStack(spacing: 15){
WebImage(url: URL(string: notification.sender!.avatar!.userAvatarPathSmall()))
.resizable()
.indicator(.activity)
.aspectRatio(contentMode: .fill)
.animation(.easeInOut(duration: 0.5))
.transition(.fade)
.frame(width: 48, height: 48)
.cornerRadius(24)
Text(notification.sender!.name!).fontWeight(.bold) + Text(notification.message!)
}.padding(.vertical)
}.onDelete(perform: delete)
}.swipeActions()
}else{
LoadingView()
}
}
.navigationBarTitle("Notifications")
}.onAppear(){
self.viewModel.getNotifications()
}
}
}
struct NotificationsTab_Previews: PreviewProvider {
static var previews: some View {
NotificationsTab()
}
}
