Purpose
Section titled “Purpose”SwiftUI Expert Skill: expert best-practices guidance for AI coding tools in Agent Skills format. Covers state management (property wrappers, @Observable, data flow), view composition/extraction/identity, performance (hot paths, lazy, granularity), lists & ForEach (stable id, Table, filtering), navigation/sheets (NavigationStack/SplitView, Inspector, enum sheets), Swift Charts (marks/axes/selection/styling/a11y/Chart3D), animations (implicit/explicit, transitions, keyframes, @Animatable), macOS (scenes, multi-window, Table, styling, AppKit interop), iOS 26+ Liquid Glass effects + fallbacks, accessibility (VoiceOver, Dynamic Type, traits), image optimization (AsyncImage, downsampling, cache), latest APIs migration (iOS 15+), previews, focus/scroll/text/layout patterns, localization. Includes unique executable Python xctrace-based Instruments trace recorder/analyzer (time profiler, hangs, hitches, SwiftUI updates/causes) for diagnosing perf issues with structured JSON+md output. Non-opinionated, correctness/performance focus. 16.6k weekly installs, 3k stars. MIT. Complements author’s Swift Concurrency skill.
Harness Coverage
Section titled “Harness Coverage”Target agents: antigravity, claude-code, codex, crush, cursor, gemini-cli, github-copilot, grok, opencode. Install: npx skills add … —skill swiftui-expert-skill; Claude Code plugin (marketplace + install, or .claude/settings.json for teams); Cursor plugin; Codex via agents/openai.yaml or copy; pi pkg mgr; manual symlink. Skill + 20+ references/ load on-demand.
Trust And Risks
Section titled “Trust And Risks”Curated install-now-after-trust-gate / curated-trust-gated. MIT. High adoption (16.6k weekly). Authors AvdLee (Antoine van der Lee, SwiftLee) + Omar Elsayed. 261 commits, frequent releases (4.0.0). Strong structure with SKILL.md + references/ + executable tools for traces. Maintenance workflow for API freshness (requires Sosumi MCP). Complements avdlee/swift-concurrency-agent-skill per config. Risks: domain-specific UI guidance; review generated SwiftUI for target iOS/macOS versions; trace tools require Xcode/xctrace and device/sim access; high visibility reduces unknown risk but always audit before broad adoption. npx provenance verified.

Upstream Maintainer
Section titled “Upstream Maintainer”AvdLee / Antoine van der Lee + Omar Elsayed (github.com/AvdLee/SwiftUI-Agent-Skill; avanderlee.com, swiftdifferently.com). MIT. 3k stars. Companion skills from author: Swift Concurrency, Core Data, Swift Testing. Inspired by Dimillian/Skills and jordibruin Swift Charts Examples. Includes AGENTS.md, CONTRIBUTING, release automation. Active sponsorship.
Comparable Alternatives
Section titled “Comparable Alternatives”Author’s swift-concurrency (same maintainer); other SwiftUI or iOS UI skills (e.g. from Dimillian or antfu web-design); official Apple SwiftUI / Human Interface Guidelines docs + sample code; Instruments + SwiftUI inspector without agent skill layer; general mobile UI or design system skills.
