Build direct Bluetooth Low Energy central or peripheral workflows with Core Bluetooth, including GATT discovery, state restoration, MTU sizing, and background modes. Use for BLE scanning, peripheral connection, characteristic reads/writes/notifications, or peripheral advertisement.

Build or review persistence in apps that still use Core Data, including managed objects, fetched results, batch operations, persistent history, staged migration, and concurrency. Use for Core Data-only work; route SwiftData adoption or coexistence to swiftdata.

Builds custom tactile and synchronized audio-haptic experiences with Core Haptics, including CHHapticEngine lifecycle, transient and continuous events, dynamic parameters, parameter curves, AHAP files, and device verification. Use when system sensoryFeedback or UIFeedbackGenerator patterns cannot express the required haptic behavior.

Integrates and profiles Core ML models for on-device inference. Use for mlmodel/mlpackage loading, generated or feature-provider predictions, compute-unit selection, MLTensor, Vision integration, MLComputePlan, model pipelines, deployment, or performance analysis.

Builds sensor workflows with Core Motion for accelerometer, gyroscope, device motion, pedometer, activity recognition, altitude, headphone motion, workout motion, and submersion/depth data. Use for motion interaction, steps, activity classification, AirPods tracking, or watchOS depth features.

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 Apple CryptoKit for Swift cryptographic primitives. Use when hashing with SHA-2 or SHA-3, generating HMACs, encrypting with AES-GCM or ChaChaPoly, signing with P256/P384/P521/Curve25519 or ML-DSA keys, performing ECDH, HPKE, ML-KEM, or X-Wing key exchange, using Secure Enclave CryptoKit keys, or migrating CommonCrypto code to CryptoKit.

Builds CryptoTokenKit security-token and smart-card integrations. Use for token-driver extensions, token sessions, TKSmartCard communication, NFC smart-card sessions, token-backed Keychain queries, token watching, certificate authentication, APDU handling, or PIN workflows.

Debug iOS apps and profile performance using LLDB, the interactive Memory Graph Debugger, and Instruments. Use for crashes, retain-cycle inspection, hangs, build failures, and generic CPU, memory, energy, or network profiling. Use ios-memgraph-analysis for .memgraph capture, leaks CLI ownership paths, or persistent heap growth; use ios-ettrace-performance for ETTrace capture and JSON.

Protects apps and APIs with DeviceCheck and App Attest. Use for per-device fraud state, App Attest key generation and attestation, request assertions, server verification, compromised-device signals, app authenticity, replay resistance, or sensitive endpoint protection.

Control motorized camera docks and enable intelligent subject tracking using DockKit. Use when discovering DockKit-compatible accessories, implementing camera subject tracking for faces or bodies, controlling dock motors for pan and tilt, configuring framing behavior, setting regions of interest, or building video apps with automatic camera tracking.

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.

Creates, reads, edits, and presents calendar events or reminders with EventKit and EventKitUI. Use for authorization, event/reminder CRUD, calendars, recurrence, alarms, change observation, event editors, viewers, calendar choosers, or SwiftUI wrappers.

Request Screen Time authorization with FamilyControls, pick apps and web domains with FamilyActivityPicker, apply shields via ManagedSettings, and monitor usage schedules with DeviceActivity in iOS.

Access eligible Wallet financial data using FinanceKit and FinanceKitUI. Use when querying transactions or balances, reading Apple Card, Apple Cash, Savings, or U.K. connected-account data, requesting financial-data authorization, using TransactionPicker, enabling iOS 26 background delivery, or saving and checking Wallet orders.

Implement or debug keyboard, directional, and scene-level focus across SwiftUI and UIKit. Use for FocusState, focus restoration and routing, tvOS remote navigation, watchOS crown focus, visionOS input focus, macOS key loops, UIFocusGuide, or UIFocusDebugger.

Builds Game Center features with GameKit. Use for local-player authentication and restrictions, access point/dashboard, leaderboards, achievements, challenges, saved games, invitations, real-time or turn-based matchmaking, match data, and server identity verification.

Standardized Git branch creation, naming taxonomies (feat/, fix/, refactor/, hotfix/, release/, chore/), trunk-based integration, and PR isolation lifecycles. Use when creating branches, preparing pull requests, or standardizing team git workflows; do not use for resolving merge conflicts or low-level git plumbing.

Builds HealthKit authorization, sample reads/writes, statistics, background delivery, and workout sessions. Use for Apple Health metrics, charts, HKQuantitySample storage, HKLiveWorkoutBuilder, unit handling, workout recording, or health-data delivery and privacy behavior.

Control smart-home accessories and commission Matter devices using HomeKit and MatterSupport. Use when managing homes/rooms/accessories, creating action sets or triggers, reading accessory characteristics, onboarding Matter devices, or building a third-party smart-home ecosystem app.
