Production-grade mobile app development with Swift (iOS), Kotlin (Android), React Native, and WebView patterns, including UI/UX, navigation, state management, networking, local storage, push notifications, and App Store deployment.
General Guide for iOS App Development, Building, Signing, Testing and App Store Listing Process (China Region). Triggered when users ask about iOS development/listing/review/signing/TestFlight/App Store Connect/privacy compliance/subscription configuration, or input the trigger word iosdev.
Implement VIP (View-Interactor-Presenter) Clean Architecture for iOS apps requiring maximum testability, unidirectional data flow, and protocol-based boundaries. Use when refactoring complex features or building enterprise apps with strict separation of concerns.
Appwrite Swift SDK skill. Use when building native iOS, macOS, watchOS, or tvOS apps, or server-side Swift applications with Appwrite. Covers client-side auth (email, OAuth), database queries, file uploads, real-time subscriptions with async/await, and server-side admin via API keys for user management, database administration, storage, and functions.
Implement, review, or improve accessibility in iOS/macOS apps with SwiftUI and UIKit. Use when adding VoiceOver support with accessibility labels, hints, values, and traits; when grouping or reordering accessibility elements; when managing focus with @AccessibilityFocusState; when supporting Dynamic Type with @ScaledMetric; when building custom rotors or accessibility actions; when auditing a11y compliance; or when adapting UI for assistive technologies and system accessibility preferences.
Implement, review, or improve App Intents for Siri, Shortcuts, Spotlight, widgets, and Apple Intelligence. Use when creating AppIntent actions, defining AppEntity models with EntityQuery, building AppShortcutsProvider phrases, adding Spotlight indexing with IndexedEntity, integrating assistant schemas for Apple Intelligence, migrating from SiriKit to App Intents, building interactive widgets with WidgetConfigurationIntent, creating Control Center widgets, implementing SnippetIntent for visual intelligence, or wiring focus filters with SetFocusFilterIntent.
Implement, review, or improve in-app purchases and subscriptions using StoreKit 2. Use when building paywalls with SubscriptionStoreView or ProductView, processing transactions with Product and Transaction APIs, verifying entitlements, handling purchase flows (consumable, non-consumable, auto-renewable), implementing offer codes or promotional/win-back/introductory offers, managing subscription status and renewal state, setting up StoreKit testing with configuration files, or integrating Family Sharing, Ask to Buy, refund handling, and billing retry logic.
Apply modern Swift language patterns and idioms for non-concurrency, non-SwiftUI code. Covers if/switch expressions (Swift 5.9+), typed throws (Swift 6+), result builders, property wrappers, opaque and existential types (some vs any), guard patterns, Never type, Regex builders (Swift 5.7+), Codable best practices (CodingKeys, custom decoding, nested containers), modern collection APIs (count(where:), contains(where:), replacing()), FormatStyle (.formatted() on dates, numbers, measurements), and string interpolation patterns. Use when writing core Swift code involving generics, protocols, enums, closures, or modern language features.
Implement alarm and countdown timer features using Apple's AlarmKit framework (iOS 26+ / iPadOS 26+). Covers AlarmManager for scheduling alarms and timers, AlarmAttributes and AlarmPresentation for Lock Screen and Dynamic Island UI, AlarmButton for stop/snooze actions, authorization flows, alarm state observation, and Live Activity integration. Use when building wake-up alarms, countdown timers with system UI, or alarm-style notifications that surface on the Lock Screen and Dynamic Island.
Encode and decode Swift types to and from JSON, property lists, and other external representations using Codable, JSONEncoder, and JSONDecoder. Use when implementing API response parsing, custom CodingKeys for key remapping, custom init(from:) or encode(to:) for complex transformations, nested or flattened JSON structures, heterogeneous array decoding, date and data decoding strategies, lossy array wrappers, Codable integration with URLSession, SwiftData, or UserDefaults, or when configuring encoder/decoder output formatting and key strategies.
Benchmark Xcode clean and incremental builds with repeatable inputs, timing summaries, and timestamped `.build-benchmark/` artifacts. Use when a developer wants a baseline, wants to compare before and after changes, asks to measure build performance, mentions build times, build duration, how long builds take, or wants to know if builds got faster or slower.
Access research-grade sensor data using SensorKit. Use when reading ambient light levels, accelerometer data, rotation rates, device usage patterns, keyboard metrics, or media events for approved research studies. Requires SensorKit entitlement and research study authorization.
