Query grid electricity forecasts and submit load events using EnergyKit to help users optimize home electricity usage. Use when building smart home apps, EV charger controls, HVAC scheduling, or energy management dashboards that guide users to use power during cleaner or cheaper grid periods.
Use for Core Location troubleshooting - no location updates, background location broken, authorization denied, geofence not triggering
Use when implementing navigation patterns, choosing between NavigationStack and NavigationSplitView, handling deep links, adopting coordinator patterns, or requesting code review of navigation implementation - prevents navigation state corruption, deep link failures, and state restoration bugs for iOS 18+
Use when debugging 'file not syncing', 'CloudKit error', 'sync conflict', 'iCloud upload failed', 'ubiquitous item error', 'data not appearing on other devices', 'CKError', 'quota exceeded' - systematic iCloud sync diagnostics for both CloudKit and iCloud Drive
Superwall quickstart for native iOS apps (Swift/Objective-C). Use for iOS SDK setup.
Use when capturing iOS simulator console output, diagnosing runtime crashes, viewing print/os_log output, or needing structured app logs for analysis. Reference for xclog CLI covering launch, attach, list modes with JSON output.
Guides the agent through upgrading a Capacitor app from v6 to v7. Use when the project is on Capacitor 6 and needs the v7 migration path. Do not use for other major versions, plugin-only upgrades, or non-Capacitor apps.
End-to-end product development for iOS/macOS apps. Covers market research, competitive analysis, PRD generation, architecture specs, UX design, implementation guides, testing, and App Store release. Use for product planning, validation, or generating specification documents.
SwiftUI NavigationStack, NavigationSplitView, and navigation transition patterns for iOS 16-18+. Covers @Observable coordinators, zoom transitions, hero animations, sheet vs push decisions, multi-step flows, anti-patterns, performance, accessibility, deep linking, and state restoration. This skill should be used when designing navigation hierarchies, implementing screen transitions, choosing between sheet and push, orchestrating multi-step flows, using @Observable with @Environment and @Bindable, or reviewing navigation code for anti-patterns.
Implement, review, or improve SwiftUI animations and transitions. Use when adding implicit or explicit animations with withAnimation, configuring spring animations (.smooth, .snappy, .bouncy), building phase or keyframe animations with PhaseAnimator/KeyframeAnimator, creating hero transitions with matchedGeometryEffect or matchedTransitionSource, adding SF Symbol effects (bounce, pulse, variableColor, breathe, rotate, wiggle), implementing custom Transition or CustomAnimation types, or ensuring animations respect accessibilityReduceMotion.
Collect and analyze on-device performance metrics and crash diagnostics using MetricKit. Use when setting up MXMetricManager, handling MXMetricPayload or MXDiagnosticPayload, processing crash/hang/disk-write diagnostics via MXCallStackTree, adding custom signpost metrics, or uploading telemetry to an analytics backend.
Use when creating SwiftData custom schema migrations with VersionedSchema and SchemaMigrationPlan - property type changes, relationship preservation (one-to-many, many-to-many), the willMigrate/didMigrate limitation, two-stage migration patterns, and testing migrations on real devices
