Legacy interoperability skill for Storyboard and Interface Builder maintenance in iOS 26 / Swift 6.2 clinic codebases. Use only for migration or maintenance of existing storyboard screens; not for new SwiftUI clinic feature development. Triggers on Auto Layout, segues, size classes, IB accessibility, storyboard merge conflicts, and storyboard-to-SwiftUI migration tasks.
Use when implementing location services, maps, geofencing, or debugging location/MapKit issues. Covers Core Location, CLMonitor, MapKit, annotations, directions.
Track build processing, find latest builds, and clean up old builds with asc. Use when managing build retention or waiting on processing.
PostHog integration for Swift iOS and macOS applications
Use when implementing iOS 26 Liquid Glass effects in SwiftUI. Covers glassEffect modifier, GlassEffectContainer, morphing with glassEffectID, and correct parameter usage.
Build, review, or improve Core Data persistence in apps that have not adopted SwiftData. Use when working with NSManagedObject subclasses, NSFetchedResultsController for list-driven UI, NSBatchInsertRequest / NSBatchDeleteRequest / NSBatchUpdateRequest for bulk operations, NSPersistentHistoryChangeRequest for persistent history tracking and multi-target sync, NSStagedMigrationManager for staged schema migrations (iOS 17+), NSCompositeAttributeDescription for composite attributes (iOS 17+), or when integrating Core Data threading with Swift Concurrency. For Core Data + SwiftData coexistence or migration, see the swiftdata skill instead.
Use when working with HealthKit, WorkoutKit, health data, workouts, or fitness features on iOS or watchOS. Covers permissions, queries, background delivery, custom workouts, multidevice coordination.
Use when needing thread-safe primitives for performance-critical code. Covers Mutex (iOS 18+), OSAllocatedUnfairLock (iOS 16+), Atomic types, when to use locks vs actors, deadlock prevention with Swift Concurrency.
Use for Core Location implementation patterns - authorization strategy, monitoring strategy, accuracy selection, background location
Expert Coordinator pattern decisions for iOS/tvOS: when coordinators add value vs overkill, parent-child coordinator hierarchy design, SwiftUI vs UIKit coordinator differences, and flow completion handling. Use when designing navigation architecture, implementing multi-step flows, or decoupling views from navigation. Trigger keywords: Coordinator, navigation, flow, parent coordinator, child coordinator, deep link, routing, navigation hierarchy, flow completion
Expert MVVM decisions for iOS/tvOS: choosing between ViewModel patterns (state enum vs published properties vs Combine), service layer boundaries, dependency injection strategies, and testing approaches. Use when designing ViewModel architecture, debugging data flow issues, or deciding where business logic belongs. Trigger keywords: MVVM, ViewModel, ObservableObject, @StateObject, service layer, dependency injection, unit test, mock, architecture
Expert quality gate decisions for iOS/tvOS: which gates matter for your project size, threshold calibration that catches bugs without blocking velocity, SwiftLint rule selection, and CI integration patterns. Use when setting up linting, configuring CI pipelines, or calibrating coverage thresholds. Trigger keywords: SwiftLint, SwiftFormat, coverage, CI, quality gate, lint, static analysis, pre-commit, threshold, warning
