Skillshub ios-app-lifecycle

Standards for AppDelegate, SceneDelegate, Deep Linking, and Background Tasks. Use when managing iOS app lifecycle, deep linking, or background task scheduling. (triggers: AppDelegate.swift, SceneDelegate.swift, didFinishLaunchingWithOptions, willConnectTo, backgroundTask, Shortcut, UserActivity)

iOS App Lifecycle Standards

Priority: P0

Implementation Guidelines

App & Scene Delegate

  • SceneDelegate: Use for UI windows and scene-specific state in iOS 13+.
  • AppDelegate: Focus on app-wide setup (DI, Analytics, Push notification registration).
  • Slim Delegates: Move initialization logic to dedicated 
    Bootstrapper
    or 
    AppCoordinator
    .

Deep Linking

  • Universal Links: Prefer over custom URL schemes. Handle via 
    scene(_:continue:userActivity:)
    .
  • Handling logic: Routing should be handled by the Root Coordinator to navigate to specific screens.

Background Tasks

  • Background Fetch: Use 
    BGTaskScheduler
    for periodically refreshing data.
  • Expiration: Handle 
    expirationHandler
    to avoid app kill by the system.

Anti-Patterns

  • No complex logic in didFinishLaunching: Use a Bootstrapper service.
  • No UIWindow setup in AppDelegate: Use SceneDelegate for iOS 13+.
  • No synchronous network calls in launch: Move to background thread.
