iOS 16 introduced a new way to navigate with NavigationStack. You may be thinking “wait, NavigationView is essentially a stack, so what’s the difference?”. That’s a great question.

NavigationStack {
  List(artworks) { artwork in ...}
List(artworks, id: \.self) { artwork in
List(artworks) { artwork in
  NavigationLink(value: artwork) {
.navigationDestination(for: Artwork.self) { artwork in
  DetailView(artwork: artwork)
