Build lightweight App Clip experiences for instant iOS app access without full installation. Covers target setup, invocation URL handling, experience configuration, size limits, invocation methods (NFC, QR, App Clip Codes, Safari banners, Maps, Messages), NSUserActivity handling, data migration to the full app via shared App Group containers, SKOverlay for full-app promotion, location confirmation with APActivationPayload, lifecycle considerations, and capability limitations. Use when creating App Clips or configuring App Clip invocation and data migration.
Read, write, and query Apple Health data using HealthKit. Covers HKHealthStore authorization, sample queries, statistics queries, statistics collection queries for charts, saving HKQuantitySample data, background delivery, workout sessions with HKWorkoutSession and HKLiveWorkoutBuilder, HKUnit, and HKQuantityTypeIdentifier values. Use when integrating with Apple Health, displaying health metrics, recording workouts, or enabling background health data delivery.
Access accelerometer, gyroscope, magnetometer, pedometer, and activity-recognition data using CoreMotion. Use when reading device sensor data, counting steps, detecting user activity (walking/running/driving), tracking altitude changes, or implementing motion-based interactions in iOS/watchOS apps.
Create child communication safety experiences using PermissionKit to request parental permission for children. Use when building apps that involve child-to-contact communication, need to check communication limits, request parent/guardian approval, or handle permission responses for minors.
Increase widget visibility on Apple Watch using RelevanceKit. Use when providing contextual relevance signals for watchOS widgets, declaring time-based or location-based relevance, combining multiple relevance providers, or helping the system surface the right widget at the right time on watchOS 26.
Manages iOS Simulator devices and tests app behavior using xcrun simctl. Covers device lifecycle (create, boot, shutdown, erase, delete), app install and launch, push notification simulation, location simulation, permission grants via privacy subcommand, deep link testing via openurl, status bar overrides, screenshot and video recording, log streaming with os_log filtering, get_app_container paths, and #if targetEnvironment(simulator) compile-time checks. Use when creating or managing simulator devices, testing push notifications without APNs, simulating GPS locations, granting or resetting privacy permissions, capturing screenshots or screen recordings from the command line, streaming device logs, debugging simulator boot failures, troubleshooting CoreSimulator issues, or checking simulator hardware limitations.
Implement, review, or improve Live Activities and Dynamic Island experiences in iOS apps using ActivityKit. Use when building real-time updating widgets for the Lock Screen and Dynamic Island — delivery tracking, sports scores, ride-sharing status, workout timers, media playback, or any time-sensitive information that updates in real time. Trigger for any task involving ActivityKit, ActivityAttributes, Activity lifecycle (request/update/end), Dynamic Island layouts (compact/minimal/expanded), push-to-update Live Activities, or Lock Screen live widgets.
Read and write NFC tags using CoreNFC. Use when scanning NDEF tags, reading ISO7816/ISO15693/FeliCa/MIFARE tags, writing NDEF messages, handling NFC session lifecycle, configuring NFC entitlements, or implementing background tag reading in iOS apps.
Use when a user wants an agent to convert USDT BEP20 into UAH payout instructions through a verified exchange flow with approval, expiry, AML screening, and payment monitoring.
Build React Native 0.76+ apps with Expo SDK 52-54. Covers mandatory New Architecture (0.82+/SDK 55+), React 19 changes, SDK 54 breaking changes (expo-av, expo-file-system, Reanimated v4), and Swift iOS template. Prevents 16 documented errors. Use when building Expo apps, migrating to New Architecture, upgrading to SDK 54+, or fixing Fabric, TurboModule, propTypes, expo-updates crashes, or Swift AppDelegate errors.
Guide for writing Expo native modules and views using the Expo Modules API (Swift, Kotlin, TypeScript). Covers module definition DSL, native views, shared objects, config plugins, lifecycle hooks, autolinking, and type system. Use when building or modifying native modules for Expo.
Implement Clerk authentication for Expo and React Native apps using @clerk/expo source-guided patterns. Use for prebuilt AuthView/UserButton or custom hook-driven auth flows. Do not use for native iOS/Swift, native Android/Kotlin, or web framework projects.
