Coding-agent prompt

You're working with SwiftUI. Apple's native declarative UI framework for iOS, iPadOS, macOS, watchOS, and visionOS.

Best practices:
- Lean on: first-class apple-platform integration
- Lean on: best-in-class performance and polish
- Lean on: full access to every new os api

Things to watch for:
- Watch out for: ios / apple-only
- Watch out for: requires xcode on macos to build

General guidance:
- Canonical docs: https://developer.apple.com/xcode/swiftui — check here before inventing APIs.
- Keep secrets in environment variables, never commit them.
- Write TypeScript where the ecosystem supports it; add types to every exported function.
- Add tests for the critical paths before declaring the task done.
- Read-the-docs is usually faster than guessing — cite the docs page in code comments when you apply a non-obvious pattern.
