I noticed on the Find My app in the new iOS 26 beta that the TabView and the sheet seem to be part of the same view. When you collapse the sheet, the TabView is still visible, and you can swipe up to view the sheet again. Is there a way to recreate this effect? Preferably in SwiftUI, but UIKit works too.
iOS 26: How to achieve TabView effect like in the Find My app.
Is it possible that this isn't actually a TabView but instead a custom sheet that has the interactiveDismissDisabled(_:) and .presentationDetents() maybe?
Just a thought anyway as the map behind is unchanged by selections on the bottom buttons.
