The tutorial says this code should animate the button by moving it up and down, and the rectangle by scaling it in and out, but I'm seeing something different. The button does animate up and down, but the red rectangle only animates out. It just appears abruptly without animation. Any ideas?

struct ContentView: View {
    @State private var isShowingRed = false

    var body: some View {
        VStack {
            Button("Tap Me") {
                withAnimation {
                    self.isShowingRed.toggle()
                }
            }

            if isShowingRed {
                Rectangle()
                    .fill(Color.red)
                    .frame(width: 200, height: 200)
                    .transition(.scale)
            }
        }
    }
}

Hi Joshua,

I just tried this code and it appears to work in the simulator but not the SwiftUI preview screen. Could be a bug, have you tried it on your iPhone?

Hope this helps

PS. I sometimes find things don't work in preview or even in the simulator, but work fine on an actual device.
