SwiftUI Agent Skill: Build better views with AI
Article Summary
Antoine van der Lee from SwiftLee introduces an open-source Agent Skill that teaches AI to write better SwiftUI code. No more fixing the same mistakes over and over in your AGENTS.md file.
This article announces a new SwiftUI Agent Skill available on GitHub that helps AI coding assistants (like Cursor) build better SwiftUI views from the start. The skill includes detailed references on performance patterns, modern APIs, state management, and common pitfalls like the onChange() modifier variants. It's designed to reduce tech debt and improve code quality when developing with AI agents.
Key Takeaways
- Open-source skill replaces repetitive AGENTS.md fixes with reusable SwiftUI knowledge
- Includes 11 reference files covering layout, performance, navigation, and iOS 26 features
- Analyzes existing views for nested scrolling, redundant updates, and deprecated APIs
- Agents reference the skill automatically to build better views from initial versions
- Built collaboratively with Omar Elsayed and accepting community contributions
The SwiftUI Agent Skill helps AI assistants write production-quality SwiftUI code by encoding best practices once instead of fixing the same issues repeatedly.
About This Article
AI agents kept making the same SwiftUI mistakes, like using the single-parameter onChange() modifier variant. This forced developers to manually update AGENTS.md files across multiple projects with the same instructions over and over.
Antoine van der Lee and Omar Elsayed built an open-source SwiftUI Agent Skill with 11 reference files. It covers image optimization, layout patterns, performance, and modern APIs. Agents can now discover and apply best practices on their own.
The skill helps agents spot specific issues during development, like nested ScrollViews that cause awkward scrolling or redundant onAppear and onChange handlers in initial view creation. This cuts down on manual refactoring work and keeps tech debt from piling up.
