`.navigationDestination` wrapper for enum cases doesn't appear to do anything

[gmedori]

Description

I just started using this library for the first time after having watched the Modern SwiftUI series on pointfree.co and it looks like the .navigationDestination modifier isn't navigating to the intended view. The .sheet modifier works as expected though.

Checklist

• I have determined whether this bug is also reproducible in a vanilla SwiftUI project.
• If possible, I've reproduced the issue using the main branch of this package.
• This issue hasn't been addressed in an existing GitHub issue or discussion.

Expected behavior

I expected a parent view to navigate to a detail view within a navigation stack.

Actual behavior

It didn't do anything.

Steps to reproduce

I've thrown together a sample project illustrating this issue. Hopefully this captures the behavior you need.

@gposcidonio Your sample project has the navigationDestination view modifier applied outside the NavigationStack view, which prevents it from working (same goes for the vanilla modifier that comes with SwiftUI). Moving navigationDestination into the NavigationStack fixes things, though we should note that navigationDestination has had a buggy history in vanilla SwiftUI, and so you may want to look out for those bugs and file feedback with Apple if you encounter them.

I'm going to convert this to a discussion since it's not a bug in the library.
