Hi mlb50,
thank you for you kind feedback!
Sorry for not replying earlier. I didn’t see your message. 
I will update the book for the new privacy controls in Core Location.
About the map component in SwiftUI, I think about rewriting the first chapter using SwiftUI. But this won’t come this year. UIKit is still very relevant and I love about my book that it uses Storyboard, UI in code and SwiftUI.
