Chapter 27 - iOS Apprentice - where did SceneDelegate go?

UIKit, unwanted SceneDelegate, can't reference window in AppDelegate

Trying to reference window in AppDelegate is nil. iOS_apprentice_v8.2.1 “When you switch to building apps with the UIKit framework later in this book, you’ll only see AppDelegate.swift” This is not true. iOS_apprentice_v8.2.1 Page 503: “Most importantly: Uncheck the Use SwiftUI checkbox! This is how you tell Xc…

The old instructions aren’t updated, only the updated SceneDelegate code snippet.
