# iOS System Integration Router

**You MUST use this skill for ANY iOS system integration including Siri, Shortcuts, widgets, in-app purchases, camera, photo library, audio, axiom-haptics, and more.**

## When to Use

Use this router for:
- Siri & Shortcuts (App Intents)
- Apple Intelligence integration
- Widgets & Live Activities
- In-app purchases (StoreKit)
- Camera capture (AVCaptureSession)
- Photo library & pickers (PHPicker, PhotosPicker)
- Audio & haptics
- Localization
- Privacy & permissions
- Spotlight search
- App discoverability
- Alarms (AlarmKit)
- Background processing (BGTaskScheduler)
- Location services (Core Location)
- Maps & MapKit (Map, MKMapView, annotations, search, directions)
- Passkeys & authentication (ASAuthorizationController, WebAuthn)
- App integrity & fraud prevention (App Attest, DeviceCheck)

## Cross-Domain Routing

When integration issues overlap with other domains:

**Widget + data sync issues** (widget not showing updated data):
- Widget timeline not refreshing → **stay in ios-integration** (extensions-widgets)
- SwiftData/Core Data not shared with extension → **also invoke ios-data** — App Groups and shared containers are data-layer concerns
- Background refresh timing → **also invoke ios-concurrency** if async patterns are involved

**Live Activity + push notification issues**:
- ActivityKit push token setup, Live Activity not updating → **stay in ios-integration** (extensions-widgets)
- Push notification delivery failures, APNs errors → **also invoke ios-networking** (networking-diag)
- Entitlements/certificates misconfigured → **also invoke ios-build** (xcode-debugging)

**Camera + permissions + privacy**:
- Camera code issues → **stay in ios-integration** (camera-capture)
- Privacy manifest or Info.plist issues → **stay in ios-integration** (privacy-ux)
- Build/entitlement errors → **also invoke ios-build**

**MapKit + location issues** (user location not showing on map):
- Map display, annotations, search → **stay in ios-integration** (mapkit)
- Location authorization, monitoring, background location → **also invoke ios-performance** or **ios-integration** (core-location)
- Map performance with many annotations → **also invoke ios-performance** if profiling needed

**Push notification + Live Activity issues** (push not updating Live Activity):
- Push transport, APNs headers, token management → **stay in ios-integration** (push-notifications, push-notifications-diag)
- ActivityKit UI, attributes, Dynamic Island → **also invoke ios-integration** (extensions-widgets)
- Background execution timing → **also invoke ios-concurrency** if async patterns are involved

**Push notification + background processing** (silent push not triggering background work):
- Push payload and delivery → **stay in ios-integration** (push-notifications-diag)
- Background execution, BGTaskScheduler → **also invoke ios-integration** (background-processing)

- Search and directions
- 8 anti-patterns

**MapKit API reference** → `/skill axiom-mapkit-ref`
- SwiftUI Map API

## Decision Tree

1. App Intents / Siri / Apple Intelligence? → app-intents-ref
2. App Shortcuts? → app-shortcuts-ref
3. App discoverability / Spotlight? → app-discoverability, core-spotlight-ref
4. Widgets / Live Activities? → extensions-widgets, extensions-widgets-ref
5. In-app purchases / StoreKit? → in-app-purchases, storekit-ref
6. Want IAP audit (missing finish, receipt validation)? → iap-auditor (Agent)
7. Want full IAP implementation? → iap-implementation (Agent)
8. Camera capture? → camera-capture (patterns), camera-capture-diag (debugging), camera-capture-ref (API)
9. Want camera code audit? → camera-auditor (Agent)
10. Photo pickers / library? → photo-library (patterns), photo-library-ref (API)
11. Audio / AVFoundation? → avfoundation-ref
12. Now Playing? → now-playing, now-playing-carplay, now-playing-musickit
13. Haptics? → haptics

18. Need APNs payload format, headers, or JWT auth details? → push-notifications-ref
19. Push notifications not arriving, token issues, or delivery failures? → push-notifications-diag
20. Location services? → core-location (patterns), core-location-diag (debugging), core-location-ref (API)
21. Maps / MapKit / annotations / directions? → mapkit (patterns), mapkit-ref (API), mapkit-diag (debugging)
22. Alarms / AlarmKit? → alarmkit-ref
23. Passkeys / WebAuthn / replacing passwords / ASAuthorizationController? → passkeys
24. App Attest / DeviceCheck / fraud prevention / app integrity? → app-attest

## Anti-Rationalization

| Thought | Reality |
|---------|---------|
| "App Intents are just a protocol conformance" | App Intents have parameter validation, entity queries, and background execution. app-intents-ref covers all. |
| "Widgets are simple, I've done them before" | Widgets have timeline, interactivity, and Live Activity patterns that evolve yearly. extensions-widgets is current. |
| "I'll add haptics with a simple API call" | Haptic design has patterns for each interaction type. haptics skill matches HIG guidelines. |
| "Localization is just String Catalogs" | Xcode 26 has type-safe localization, generated symbols, and #bundle macro. localization skill is current. |
| "Camera capture is just AVCaptureSession setup" | Camera has interruption handlers, rotation, and threading requirements. camera-capture covers all. |
| "I'll just use MKMapView, I know it already" | SwiftUI Map is 10x less code for standard map features. mapkit has the decision tree. |
| "MapKit search doesn't work, I'll use Google Maps SDK" | MapKit search needs region bias and resultTypes configuration. mapkit-diag fixes this in 5 minutes. |
| "Alarm scheduling is just UNNotificationRequest" | AlarmKit (iOS 26+) has dedicated alarm UI, authorization, and Live Activity integration. alarmkit-ref covers the framework. |
| "Push notifications are just a payload and a token" | Token lifecycle, Focus interruption levels, service extension gotchas, and sandbox/production mismatch cause 80% of push bugs. push-notifications covers all. |
| "Our users aren't ready for passkeys" | Apple, Google, and Microsoft ship passkeys across all platforms. Users don't need to understand crypto — they just tap. passkeys covers the migration path. |
| "App Attest is overkill for our app" | Any app with server-side value (premium content, virtual currency, user accounts) is a fraud target. app-attest has a gradual rollout strategy. |
