onDelete confirmation for onDelete

[derech1e]

Can you add a feature, that you can confirm a delete action?

Thank you.

Hey @derech1e ,

on iOS < 15 you have to use

@State private var deletedIndexSet: IndexSet?
@State private var isDeleteConfirmationDialogPresented = false

yourAdvancedList
.onDelete { indexSet in
    deletedIndexSet = indexSet
    isDeleteConfirmationDialogPresented = true
}
.alert(isPresented: $isDeleteConfirmationDialogPresented) {
    Alert(
        title: Text("Delete"),
        message: Text("Are you sure?"),
        primaryButton: .destructive(Text("Yes"), action: {
            guard let indexSet = deletedIndexSet else {
                return
            }
            yourItems.remove(atOffsets: indexSet)
        }),
        secondaryButton: .cancel()
    )
}

For iOS 15 I recommend the following

@State private var deletedIndexSet: IndexSet?
@State private var isDeleteConfirmationDialogPresented = false

AdvancedList(yourItems, content: { item in
    view(for: item)
        .swipeActions {
            Button(role: .destructive) {
                guard let index = yourItems.firstIndex(where: { $0.id == item.id }) else {
                    return
                }
                deletedIndexSet = .init(integer: index)
                isDeleteConfirmationDialogPresented = true
            } label: {
                Text("Delete")
            }
        }
}, listState: yourListState, emptyStateView: {
    ...
}, errorStateView: { error in
    ...
}, loadingStateView: {
    ...
})
.confirmationDialog(Text("Are you sure?"), isPresented: $isDeleteConfirmationDialogPresented) {
    Button(role: .destructive) {
        guard let indexSet = deletedIndexSet else {
            return
        }
        yourItems.remove(atOffsets: indexSet)
    } label: {
        Text("Delete")
    }
}
