Animating AnyView vs Group

import SwiftUI

// Animates nicely since the type of both returns are the same, i.e. AnyView<Text>
func gimme(toggle: Bool) -> AnyView {
    if toggle {
        return AnyView(
            Text("Hello World")
        )
    } else {
        return AnyView(
            Text("Hello Worlds")
        )
    }
}

// Doesn't animate, since the two Text views are in separate conditionals
func gimme2(toggle: Bool) -> AnyView {
    AnyView (
        Group {
            if toggle {
                Text("Hello World")
            } else {
                Text("Hello Worlds")
            }
        }
    )
}


struct Animator: View {
    @State var toggle: Bool = true

    var body: some View {
        VStack {
            Toggle(isOn: $toggle) {
                Text("Toggle")
            }

            Divider()

            VStack {
                Text("Animates")
                gimme(toggle: toggle)
                    .foregroundColor(.white)
                    .background(Color.black)
            }

            Divider()

            VStack {
                Text("Doesn't animate (fade)")
                gimme2(toggle: toggle)
                    .foregroundColor(.white)
                    .background(Color.black)
            }
        }
        .frame(width: 600, height: 500)
        .animation(.easeIn(duration: 1))
    }
