Implements tactile feedback patterns and custom haptic experiences for Swift and iOS applications using industry best practices.

Foundation Models for Apple AI

Implements on-device AI features like summarization and classification using Apple's Foundation Models framework in Swift.

Swift Testing for Claude Code

Implements modern Swift Testing patterns to build robust, parallel, and macro-based test suites for Apple platforms.

Modern Swift Engineering

Implements modern Swift 6+ concurrency patterns, actors, and async/await for building safe, data-race-free applications.

In-App Purchases

Implements robust, testable in-app purchase systems using StoreKit 2 with a testing-first workflow and centralized transaction handling.

Objective-C Block Retain Cycles

Diagnoses and resolves memory leaks in Objective-C by identifying circular references in blocks and implementing the mandatory weak-strong pattern.

Database Migration

Executes safe, data-loss-free database schema evolution for iOS and macOS applications using production-ready patterns for SQLite, GRDB, and SwiftData.

AVFoundation Audio Reference

Provides comprehensive implementation guidance and reference patterns for AVFoundation audio APIs, including spatial audio capture and system audio session management.
