I think the book will be about algorithms and data structures
iOS Secrets by Tutorials
I think is “RxSwift by Tutorials”…
I think “macOS Apprentice”.
Architecture Pattern in Swift
Unity Games By Tutorials or Architecture and Design Patterns in Swift!
I’d guess cross platform tools like Xamarin, or React.
My guess is iOS 10 by Tutorials
I am a COBOL-programmer (yes, seriously), so I would welcome it! 
Maybe “Apple Watch 3” in swift
Maybe “How to become iOS developer like Ray Wenderlich”.
