    When using stack-based navigation (see Stack-based navigation) you will typically have a single enum that represents all of the destinations that can be pushed onto the stack, and you will hold that state in StackState:

    struct State {
  var path = StackState<Path.State>()
}

    You can use this subscript for a succinct syntax to modify the data in a particular case of the Path.State enum, like so:

    state.path[id: 0, case: \.edit]?.alert = AlertState {
  Text("Delete?")
}
