iOS App Lifecycle

**Priority: P0 (CRITICAL)**

Implementation Workflow

1. **Configure SceneDelegate** — Use for UI windows and scene-specific state in iOS 13+. 2. **Keep AppDelegate slim** — Focus on app-wide setup (DI, Analytics, Push registration). Move initialization logic to dedicated `Bootstrapper` or `AppCoordinator`. 3. **Handle deep links** — Prefer Universal Links over custom URL schemes. Handle via `scene(_:continue:userActivity:)`. Route through Root Coordinator. 4. **Schedule background tasks** — Use `BGTaskScheduler` for periodic data refresh. Always handle `expirationHandler` to avoid system kill.

See [bootstrapper pattern and background task examples](references/implementation.md)

Anti-Patterns

  • **No Complex AppDelegate Logic**: Delegate to Bootstrapper service
  • **No Manual AppDelegate UIWindow**: Use SceneDelegate for iOS 13+
  • **No Sync Launch Network**: Move all launch calls to background threads
