Honestly, I don’t enjoy reading this book. It’s the same reason why I didn’t enjoy reading “RxSwift Reactive Programming with Swift.” In fact, this book is just the Combine conversion of the RxSwift book. This book even uses the exactly same sample project (Collage). And the Combine book has the same approach as the RxSwift book. They both use the playground to explain some concepts. We don’t use the playground to build apps. And these books seem to share the same goal: Using either framework or library for the MVVM architecture. I bought both books to see simple examples to see how I can use them. As for the Combine framework, I want to see simple sample projects like
Combine first example
Table and collection view data sources for Combine
to find out how Combine can be useful in coding a view controller involving one or two IBOutlet objects.
