How to enable editing on a list using EditButton

If you have configured a SwiftUI list view to support deletion or editing of its items, you can allow the user to toggle editing mode for your list view by adding an EditButton somewhere.

For example, this ContentView struct defines an array of users, attaches an onDelete() method, then adds an edit button to the navigation bar:

struct ContentView: View {
    @State private var users = ["Paul", "Taylor", "Adele"]

    var body: some View {
        NavigationView {
            List {
                ForEach(users, id: \.self) { user in
                    Text(user)
                }
                .onDelete(perform: delete)
            }
            .navigationBarItems(trailing: EditButton())
        }
    }

    func delete(at offsets: IndexSet) {
        users.remove(atOffsets: offsets)
    }
}

When that is run, you’ll find you can tap the edit button to enable or disable editing mode for the items in the list.
