Project 4 is broken

Forums > watchOS


I am on Xcode Version 13.4.1 (13F100) and watchOS 8.5 (19T241)

I've recently started working on Project4 of the latest Hacking with watchOS (SwiftUI) and it seems there's a gnarly bug when using NavigationLink within a TabView that is nested inside a NavigationView. The bug is also currently present in the watchOS Github repo project.

When navigating from the initial view to the ResultsView, the latter quickly pops itself from the stack. I've uploaded a video demonstrating the behavior:

Xcode reports a SwiftUI runtime error when building the project: Accessing State's value outside of being installed on a View. This will result in a constant Binding of the initial value and will not update.

Adding NavigationLinks with empty views didn't solve the issue either.


struct Project4App: App {
    var body: some Scene {
        WindowGroup {
            NavigationView {


struct MainView: View {
    var body: some View {
        TabView {

I'm relatively new to SwiftUI (coming from UIKit), so I apologize beforehand if I'm missing anything obvious.

Edit: Here's a Github issue from another developer that reproduces this bug as well. It's safe to say it's a SwiftUI issue in that case.
