NavigationStack (Push Navigation)

Use NavigationStack with a typed [Route] binding for programmatic push navigation. Define routes as a Hashable enum and map them with .navigationDestination(for:); this keeps the path compile-time checked. Use NavigationPath only when one stack must hold heterogeneous route value types.

enum Route: Hashable {
    case item(id: Item.ID)
}

struct ContentView: View {
    @State private var path: [Route] = []
    let items: [Item]

    var body: some View {
        NavigationStack(path: $path) {
            List(items) { item in
                NavigationLink(value: Route.item(id: item.id)) {
                    ItemRow(item: item)
                }
            }
            .navigationDestination(for: Route.self) { route in
                switch route {
                case .item(let id):
                    DetailView(itemID: id)
                }
