App Architecture: iOS Application Design Patterns in Swift

This book explains a range of application design patterns and their implementation techniques using a single example app, fully implemented in five design patterns.

Instead of advocating for any particular pattern, we lay out the problems all architectures are trying to address: constructing the app’s components, communicating between the view and the model, and handling non-model state. We show high-level solutions to these problems and break them down to the level of implementation for five different design patterns — two commonly used and three more experimental.
