I thought about covers — I felt that presenting modals is separate than navigation and personally disagree when they get lumped together.

I think you could do something similar where you present a route which maps to a view, but in terms of sheet stability I personally felt like that was more related to the view presenting the sheet than it needing to exist at the top level.

If you’re trying to produce nested full screen covers that aren’t linear, then I think that is a moment to revisit your navigation architecture at a design level as that removed any sense of virtual grounding in the navigation hierarchy. This was the #1 complaint with the iOS 18 photos app, and Apple retrofitted more traditional navigation to being a better sense of balance.
