Covers testing for modular iOS 26/Swift 6.2 apps built on MVVM-C architecture with protocol-based dependency injection. You get 44 rules across unit, UI, snapshot, and async testing, organized by priority so you can focus on architecture decisions first (protocol dependencies, constructor injection) before diving into Swift Testing syntax or CI config. Everything assumes the clinic pattern where Domain defines contracts, Data owns I/O, and features stay isolated. Most useful when setting up tests for a new feature module or refactoring existing tests to work with actor isolation and stale-while-revalidate patterns. The priority system is helpful because it stops you from bikeshedding snapshot device matrices before nailing down your mock strategy.
