Expert-level retail systems, POS, inventory management, e-commerce, customer analytics, and omnichannel retail
Help developers integrate Apple MapKit into iOS/macOS apps. Use this skill when users ask to add a map to their app, display maps, show user location on a map, add markers/pins/annotations, implement map clustering, get directions/routing between locations, search for places/points of interest, implement MapKit features, work with MKMapView, SwiftUI Map, MKAnnotation, MKOverlay, MKDirections, MKLocalSearch, or any MapKit-related development task.
Superwall quickstart for native iOS apps (Swift/Objective-C). Use for iOS SDK setup.
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.
FreeRTOS skill for embedded RTOS development. Use when creating tasks, managing priorities, using queues and mutexes, detecting stack overflows, configuring FreeRTOS via FreeRTOSConfig.h, or debugging FreeRTOS applications with OpenOCD and GDB. Activates on queries about FreeRTOS tasks, queues, semaphores, mutexes, configASSERT, stack overflow, vTaskDelay, or FreeRTOS-aware debugging.
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.
Expert Core Data guidance (iOS/macOS): stack setup, fetch requests & NSFetchedResultsController, saving/merge conflicts, threading & Swift Concurrency, batch operations & persistent history, migrations, performance, and NSPersistentCloudKitContainer/CloudKit sync.
Use when encountering BUILD FAILED, test crashes, simulator hangs, stale builds, zombie xcodebuild processes, "Unable to boot simulator", "No such module" after SPM changes, or mysterious test failures despite no code changes - systematic environment-first diagnostics for iOS/macOS projects
