Apple Engineer Superpowers

What it does

This skill provides comprehensive knowledge of Apple platform engineering for AI coding assistants. It covers Swift 6 concurrency, SwiftUI, Metal GPU programming, RealityKit & visionOS development, and advanced Swift patterns – areas often overlooked by other skills. The goal is to enable your AI agent to generate correct, modern Swift code reflecting best practices from experienced Apple engineers.

When to use it

• Complex Concurrency: When you need robust asynchronous operations with isolation, error handling, and cancellation (e.g., building a network service).
• GPU Programming: For tasks involving video processing or rendering using Metal compute shaders.
• Spatial Computing: Developing immersive experiences for visionOS that leverage hand tracking and multi-window scenes.
• Modern SwiftUI Architecture: Refactoring existing code to utilize @Observable and improve data flow within your application.

Key capabilities

• Swift 6 concurrency (actors, Sendable, AsyncSequence)
• Metal GPU programming (compute/render pipelines, ring buffers)
• RealityKit & visionOS development (entity-component-system architecture, hand tracking)
• Advanced Swift patterns (enum-keyed tables, async broadcast channels, interpolation)

Example prompts

• "Build me a network service with retry and cancellation."
• "Create a Metal compute shader that processes video frames."
• "Add a hand-tracking interaction to my visionOS app."

Tips & gotchas

This skill provides detailed references; it's not a simple checklist. Expect the AI agent to generate more complex code structures reflecting production-ready patterns and best practices.
