This is your setup guide when you're building iOS apps with the clinic modular MVVM-C architecture on iOS 26 and Swift 6.2. It covers 19 rules across Xcode project configuration, SwiftData persistence, Swift Testing, Instruments profiling, and TestFlight distribution. The architecture keeps feature modules importing only Domain and DesignSystem, with the app target owning DependencyContainer and coordinator wiring. Most valuable for the SwiftData container setup and the opinionated stale-while-revalidate read pattern with optimistic queued writes. If you're working in this exact stack and architecture, the specificity is helpful. If not, the persistence and tooling sections still apply broadly to modern iOS development.
