Need to use preferredColorScheme in preview. The previous code would not change the background.

struct FirstVisitAward_Previews: PreviewProvider {
    static var previews: some View {
        Group {
            FirstVisitAward()
                 .frame(width:200,height:200)
                .preferredColorScheme(.dark).previewDisplayName("Dark")
            FirstVisitAward()
                .frame(width:200, height:200)
               .preferredColorScheme(.light).previewDisplayName("Light")
        
        }
    }
}
