Trying to figure out view transitions

I’m in Chapter 20 and trying to follow the logic using a very simple example. Here’s the code:


struct ContentView: View {
    @State var change = false
    
    var body: some View {
        Rectangle()
            .foregroundColor(change ? .red : .green)
            .frame(maxWidth: .infinity)
            .transition(.slide)
            .onTapGesture {
                withAnimation {
                    change.toggle()
                }
            }
}

What I expect to see is, when tapping the screen, the green and the red rectangles replacing each other with a sliding transition. Instead, there is a fade-in/fade-out animation, both on the simulator and the device. Why?
