iOS Agent Skills

Production-ready architectural patterns and implementation skills for building modern iOS apps with Swift, SwiftUI, and Tuist — designed as context for AI coding agents.

Created and maintained by Alp Özcan.

Why This Exists

AI coding agents are powerful, but they lack the opinionated, battle-tested architectural knowledge that comes from shipping real iOS apps. They'll happily generate a ViewController with 2,000 lines, wire up Singletons everywhere, and skip actor isolation entirely.

iOS Agent Skills is a collection of 25 self-contained skill documents that teach AI agents (and developers) how to build modular, testable, privacy-first iOS applications using modern Swift patterns. Each skill encodes a specific architectural decision — the kind of thing a senior iOS engineer carries in their head but rarely writes down.

These skills were extracted from building a production iOS app with 10+ Tuist modules, on-device LLM integration (Apple Foundation Models), StoreKit 2 subscriptions, EventKit–CoreData sync, and a fully custom SwiftUI design system. They represent real patterns that survived contact with real users.

What's Inside

25 skills organized across 5 categories, covering everything from build system configuration to on-device AI safety guardrails.

🏗️ Architecture — 7 skills

The structural backbone of a modular iOS app. These skills define how code is organized, how dependencies flow, how services communicate safely across threads, how errors propagate with full type safety, and how all workflows are orchestrated through a single entry point.
