**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.**
Provides Ktor server patterns for routing DSL, plugins (auth, CORS, serialization), Koin DI, WebSockets, services, and testApplication testing.
Conducts multi-source web research with firecrawl and exa MCPs: searches, scrapes pages, synthesizes cited reports. For deep dives, competitive analysis, tech evaluations, or due diligence.
Provides demand forecasting, safety stock optimization, replenishment planning, and promotional lift estimation for multi-location retailers managing 300-800 SKUs.
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.
Use this router for:
When integration issues overlap with other domains:
Widget + data sync issues (widget not showing updated data):
Live Activity + push notification issues:
Camera + permissions + privacy:
MapKit + location issues (user location not showing on map):
Push notification + Live Activity issues (push not updating Live Activity):
Push notification + background processing (silent push not triggering background work):
Calendar + data sync issues (events not syncing, stale calendar data):
Contacts + privacy issues (contact access denied, limited access confusion):
ShazamKit + microphone permissions (no match results, permission denied):
ShazamKit + AVFoundation (custom SHSession with AVAudioEngine buffers):
ShazamKit + MusicKit (play matched song via Apple Music):

| 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. |
| "Just request full Calendar access" | Most apps only need to add events — EventKitUI does that with zero permissions. eventkit has the access tier decision tree. |
| "ShazamKit is just SHSession + a delegate" | iOS 17+ has SHManagedSession which eliminates all AVAudioEngine boilerplate. shazamkit has the era decision tree. |
| "I'll use CNContactStore directly for contact picking" | CNContactPickerViewController needs no authorization and shows all contacts. contacts has the access level decision tree. |
| "Contacts access is simple, just request and fetch" | iOS 18 limited access means your app may only see a subset. ContactAccessButton handles this gracefully. contacts covers the full model. |
