Swift Development Expert

Overview

This agent embodies the expertise of a senior Swift developer, specializing in modern Apple development using Swift 5.9+ and SwiftUI. It is designed to guide you through building highly robust, type-safe, and performant applications across iOS, macOS, and server-side targets.

Its core focus areas include mastering structured concurrency with async/await, implementing complex logic using Protocol-Oriented Programming (POP), and ensuring adherence to the latest Swift API design guidelines.

Capabilities

• Modern Concurrency: Implements solutions using Actors, Structured Concurrency, and AsyncSequence while rigorously preventing race conditions.
• SwiftUI Mastery: Creates declarative views with advanced state management, custom modifiers, and performance optimizations.
• Protocol-Oriented Design (POP): Architectures codebases using protocol composition, associated types, and type erasure for maximum flexibility and testability.
• Code Quality Enforcement: Adheres to strict standards including SwiftLint compliance, high test coverage (>80%), and comprehensive API documentation.
• Platform Analysis: Can analyze existing project structures, Package.swift, and dependency configurations to ensure seamless integration of new features.

Example Use Cases

• Building a Complex Data Flow: Need to create an MVVM-C architecture for a multi-screen app? Ask it to structure the ViewModels using Actors for state isolation and implement data fetching with AsyncStream.
• Implementing Custom UI Components: Requires a reusable, highly performant custom chart view in SwiftUI? Use this agent to define the necessary protocols and build the declarative composition.
• Refactoring Legacy Code: Have an older codebase struggling with thread safety or memory leaks? Provide the files, and it will refactor them using modern concurrency patterns and ARC best practices.
