AlarmKit implements iOS and iPadOS alarms and countdown timers with Lock Screen, Dynamic Island, StandBy, and Apple Watch system UI. Use it when building wake-up alarms, timers, or alarm-style alerts that need AlarmKit scheduling, authorization, and Live Activity integration.

App Clips builds lightweight iOS App Clips with invocation URLs, App Clip Codes, NFC, QR, Safari banners, target setup, and App Store Connect experiences. Use it when creating an App Clip or wiring routing, handoff, notifications, or location confirmation.

App Intents implements App Intents for Siri, Shortcuts, Spotlight, widgets, Control Center, and Apple Intelligence. Use it when exposing app actions or entities to system surfaces.

App Migration Kit helps you implement one-time, system-orchestrated data migration between iOS and another platform. Use it to build AppMigrationExtension export and import flows, track progress, handle errors, and test migration logic.

App Store Optimization improves App Store search visibility and conversion for product pages. Use it for keyword strategy, metadata, screenshots, custom product pages, in-app events, reviews, and localized listings.

App Store Review Preparation audits submission readiness and rejection risk for iOS apps. Use it to check privacy manifests, ATT, StoreKit, entitlements, metadata, widgets, and Live Activities before submitting or after a rejection.

Apple On-Device AI helps you choose and implement local model runtimes on iPhone, iPad, and Mac using Foundation Models, Core ML, MLX Swift, or llama.cpp. Use it when building private AI features, running LLMs on Apple Silicon, or converting models for Core ML.

Audio Accessory Kit supports automatic audio switching for paired third-party Bluetooth headphones or earbuds. Use it when a companion app registers an accessory or an app extension reports placement or connected-source changes.

Authentication implements iOS sign-in flows with AuthenticationServices and LocalAuthentication. Use it for Sign in with Apple, passkeys, OAuth web auth, Password AutoFill, credential-state checks, token validation, or biometric re-authentication.

BrowserEngineKit helps build alternative browser engines for iOS and iPadOS using BrowserEngineKit. Use it when checking eligibility, wiring entitlements, or managing web content, networking, and rendering extension processes.

CallKit builds VoIP calling features that use the native iOS call UI. Use it for incoming and outgoing call flows, PushKit VoIP registration, audio session coordination, and call directory extensions.

CarPlay builds category-entitled, template-based iOS car display apps with the CarPlay framework. Use it when implementing navigation, audio, communication, EV charging, parking, or food ordering experiences and testing them in CarPlay Simulator.

CloudKit implements and reviews iCloud data sync for iOS and macOS apps using CKContainer, CKRecord, CKQuery, CKSubscription, CKSyncEngine, SwiftData, and iCloud Drive. Use it when handling sync setup, conflicts, account status, or CloudKit errors.

Contacts Framework shows how to fetch, create, update, and pick contacts with Contacts and ContactsUI in SwiftUI apps. Use it when handling contact permissions, CNContactStore fetch/save requests, or wrapping the contact picker.

Core Bluetooth builds direct BLE central and peripheral workflows with GATT services, characteristics, scanning, connecting, reading, writing, and notifications. Use it for post-setup Bluetooth communication, background BLE modes, and state restoration.

Core Data helps build and review persistence for apps using NSPersistentContainer, background contexts, fetched results controllers, batch operations, and staged migrations. Use it when working on Core Data threading, history tracking, or list-driven UI without SwiftData.

Core ML Swift Integration shows how to load Core ML models, configure compute units, and run predictions in iOS apps. Use it when integrating .mlmodel or .mlpackage files, batching inference, or profiling on-device performance.

Core Motion reads accelerometer, gyroscope, device motion, pedometer, altitude, headphone motion, and submersion data in Swift apps. Use it when you need sensor input for movement tracking, activity detection, or motion-based interactions.

Core NFC reads and writes NFC tags in iPhone apps using CoreNFC. Use it for NDEF scanning, native tag protocols, NDEF writing, NFC entitlements, and background tag reading.

CryptoKit uses Apple CryptoKit for hashing, HMAC, authenticated encryption, signing, key agreement, and Secure Enclave-backed keys in Swift. Use it when replacing CommonCrypto or implementing cryptographic primitives in iOS apps.
