struct ContentView: View {
    var body: some View {
        VStack {
            Color.red.frame(width: 40, height: 40)
            Color.blue.frame(width: 40, height: 40)
            HStack {
                Color.green.frame(width: 40, height: 40)
                Color.yellow.frame(width: 40, height: 40)
            }
        }
