Here it is

struct ContentView: View {
    @State var color = 0;
    var body: some View {
        Text("Hello, World!")
            .background(changeBkColor(color: self.color))


    }
}
func changeBkColor(color: Int) -> Color
{
    if(color == 1)
    {
        return Color.red;
    }
    else if(color == 2)
    {
        return Color.green;
    }
    else
    {
        return Color.blue;
    }
}
