iOS 14 requires the scope bar modifier to be on the first subview of
the NavView. This is because a VStack wraps the content.
A bug was that the segmented picker was being overlaid due to the
scope bar modifier having an AppStorage call. The AppStorage call
updated the modifier which for some reason added another HostingView.
I am not sure why this happens, but avoid using AppStorage in the modifier
to make sure this doesn't happen again.
