Clean Architecture

We will focus on the Clean Architecture concept due to its didactic and practical value: it is one of the best architectural styles you can learn about. We will keep focused on using SwiftUI while avoiding some of the worst practices I have witnessed.

There are some practicalities in adapting Clean Architecture to a Swift-based context, as the relevant frameworks are in evolution. Due to recent changes to SwiftUI, which happened during WWDC2023, you may want to give some thought to whether to use SwiftData or whether to implement a data persistence layer yourself. Before WWDC2023, we would have suggested implementing a data persistency layer using Core Data. Now, this choice, which impacts your architectural choices, has become more varied. We will cover this in Chapters 12 and 14 of this book.

Clean Architecture, a concept pioneered by the aforementioned Robert C. Martin (nicknamed “Uncle Bob”), prescribes the design of software systems with...
