I want to learn Swift & Xcode, and I found many great books in Books App on my MacBook Pro. As a new starter, I read a book which title is App Development with Swift, but I can only download the latest version with Xcode 11, but not Xcode 12. Do you know when will be an update for this book by Apple? Because the Xcode has some changes between Xcode 11 & Xcode 12, such as SwiftUI. Then, I want to know if there is any book with Xcode 12?
