Dedication
This text was prepared for publication in March 2020. As a result, a lot of the code and techniques in this book are out of date. It is provided as a historical curio, and does not provide accurate guidance on using SwiftUI today.
For Joanna, Olivia, and Jacob, who let me lock myself away for many evenings to write this book.
In Memoriam: Oli Glaser
9 March 1977 – 16 February 2020.
The crystal ship has been waiting for you, my friend.
