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. Signed-off-by: kingbri <bdashore3@proton.me>
