Sample code repository for the objc.io 'App Architecture' book, demonstrating iOS application design patterns in Swift. It contains the Recordings sample app implemented in seven architecture variants, including MVC, MVVM+Coordinator, and The Elm Architecture.

Use cases

• learn iOS app architecture patterns
• compare MVC vs MVVM implementations in Swift
• study The Elm Architecture in an iOS app
• find reference implementations of view-model coordination
• understand how to avoid massive view controllers
• explore sample Swift code for app design patterns

When to choose

• you are learning iOS application design patterns from the accompanying book
• you want side-by-side comparisons of multiple architectures in one sample app
• you teach or study Swift architecture techniques

When to avoid

• you need a production-ready framework or library to drop into your app
• you need a maintained, licensed codebase for commercial use (no license is provided)
• you work outside iOS/Swift development
