Weekly change comes from our own snapshots, not the repository page — it measures attention, not adoption.
# SwiftUI Expert Skill ## When to Use Use when writing, reviewing, or refactoring SwiftUI code for iOS or macOS, including state management and `@Observable` data flow, view composition and invalidation/performance, lists and `ForEach` identity, environment usage, localization, animations, Liquid Glass adoption, migrating... ## Operating Rules - Consult `references/latest-apis.md` at the start of every task to avoid deprecated APIs - Prefer native SwiftUI APIs over UIKit/AppKit bridging unless bridging is necessary - Focus on correctness and performance; do not enforce specific architectures (MVVM, VIPER, etc.) - Encourage separating business logic from views for testability without mandating how - Follow Apple's Human Interface Guidelines and API design patterns - Only adopt Liquid Glass when explicitly requested by the user (see `references/liquid-glass.md`) - Present performance optimizations as suggestions, not requirements - Use `#available` gating with sensible fallbacks for version-specific APIs ## Task Workflow ### Review existing SwiftUI code - Read the code under review and identify which topics apply - Flag deprecated APIs (compare against `references/latest-apis.md`) -

How do I install it?
Run `npx skills add sickn33/agentic-awesome-skills --skill swiftui-expert-skill --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.
Where does this skill come from?
From sickn33/agentic-awesome-skills, a repository with 44,414 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
