I have a view created for the iPad with a Sidebar and another for the iPhone with a tabview. The problem is that when I use sizeClass, the SideBarView() view loses its state every time the app enters the background.

This does not happen if I use the SideBarView() view without the sizeClass conditional. Without that variable, it works correctly without any problem.

var body: some View {
    #if os(iOS)
    if horizontalSizeClass == .compact {
        TabMainView()
    } else {
        SideBarView()
    }
    #else //MacOSView
        SideBarView()
    #endif
}

Any idea?
