Description
Configure AppDelegate, SceneDelegate, deep linking, and background tasks. Use when configuring iOS app lifecycle, deep linking, or background task scheduling.

iOS App Lifecycle

Priority: P0

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

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
