VRIL-LABS 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)
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

- In-app purchases / StoreKit? → in-app-purchases, storekit-ref
- Want IAP audit (missing finish, receipt validation)? → iap-auditor (Agent)
- Want full IAP implementation? → iap-implementation (Agent)
- Camera capture? → camera-capture (patterns), camera-capture-diag (debugging), camera-capture-ref (API)
- Want camera code audit? → camera-auditor (Agent)
- Photo pickers / library? → photo-library (patterns), photo-library-ref (API)
- Audio / AVFoundation? → avfoundation-ref
- Now Playing? → now-playing, now-playing-carplay, now-playing-musickit
- Haptics? → haptics
- Localization? → localization
- Privacy / permissions? → privacy-ux
- Background processing? → background-processing (patterns), background-processing-diag (debugging), background-processing-ref (API)

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. |
