The complete title of the book is App Architecture: iOS Application Design Patterns in Swift. Leading three chapters of the book is pure gold for beginners (and not only). I think this is the best overview of Apple's interpretation of MVC I've ever seen. It is better than official documentation, seriously. As for last two chapters—those are interesting and nice jigsaw puzzle pieces that should fit in your experimental patterns. At least that's how I saw them. Finally, this is not a systems design book, nor it has much to say about advanced UI manipulation patters. Very recommended.
