Implement, review, and optimize SwiftUI code with trace-backed diagnostics

Guide SwiftUI implementation and refactoring with current Apple patterns, then analyze Instruments traces to diagnose hangs, hitches, and expensive view updates.

Prerequisites

Xcode Instruments traces; SwiftUI source files; custom skill-capable agent client

Installation

Use the upstream install or setup path that matches your environment:

• npx skills add https://github.com/avdlee/swiftui-agent-skill --skill swiftui-expert-skill

Requirements and caveats from upstream:

• Unlike the other reference files — which are text guidance — this part of the skill ships an executable Python toolchain that wraps xctrace. It lets the agent record a new .trace and analyse an existing one en...
• scripts/instruments_parser/ — one module per lane (time_profiler, hangs, hitches, swiftui, causes), plus cross-lane correlate and a markdown summary renderer. Pure stdlib Python 3; only external dep is xctrace (ships...
• Use this skill after new iOS or Xcode releases to refresh the deprecated API reference. It requires the Sosumi MCP to be available. See AGENTS.md or CONTRIBUTING.md for details.

Basic usage or getting-started notes:

• bash

• For more information, visit the skills.sh platform page.

• Then use the skill in your AI agent, for example:
