I want my preview to only have the size of the view and not show the whole iPhone. I have already tried it with this code:

struct TimerCardView: View {
   
    
    var body: some View {
        Text("Hello, World!")
            .padding()
            .background(.gray)
    }
}


struct TimerCardView_Previews: PreviewProvider {
    static var previews: some View {
        TimerCardView()
            .previewLayout(.sizeThatFits)
    }
}

but nothing happened. What am I doing wrong? I appreciate help
