Guidance for how to persist navigation state between launches using swift-sharing

[cameronmcefee]

Hello!

I'd like to be able to persist the user's navigation StackState so that when they launch the app they start where they left off. I'd hoped it'd be as easy as something like:

@ObservableState
public struct State: Equatable {
+  @Shared(.appStorage("navigationPath"))
  var path = StackState<Path.State>()

  public init() {}
}

But this comes with a lot of compiler warnings. I've been digging through docs and video transcripts but haven't found anything like this. Do you have guidance for how to do this? Is it possible to do it this simply, or do I need some kind of second property where I track it and restore it in an onAppear manually?
