SwiftUI: Animate a Button View scale modifier up then back to its initial state

In the code snippet below the Button View when tapped will animate its scaleEffect up then return to its initial value.  DispatchQueue.main.asyncAfter is used to add a small delay after the first animation block. 

import SwiftUI

struct ContentView: View {

  @State private var scale: CGFloat = 1

  var body: some View {

    Button(action: {

      withAnimation(.easeIn(duration: 1)) {

        self.scale += 20


      DispatchQueue.main.asyncAfter(deadline: .now() + 0.1) {

        withAnimation(.easeIn(duration: 1)) {

          self.scale = 1



    }) {

      Image(systemName: “sun.max.fill”)

        .font(.system(size: 40))






struct ContentView_Previews: PreviewProvider {

  static var previews: some View {
