Language: Python

Missed the latest GitHub check; these facts may be older.

Overview

An Agent Skills package that gives coding agents SwiftUI reference guides covering state management, view composition, performance, navigation, Swift Charts, macOS scenes, Liquid Glass and SDK 27 changes. Reference files load on demand. It also ships Python scripts that wrap xctrace to record and analyse Instruments traces for hangs, hitches and SwiftUI view updates.

Who it is for: SwiftUI developers using Claude Code, Codex or Cursor

Strengths

Reference files load on demand, so task context stays small
Bundled stdlib-only Python scripts record and analyse .trace files, emitting JSON and markdown
Installs via skills.sh, Claude Code, Codex and Cursor plugin manifests
Covers iOS 15 through iOS 27 API migration, plus macOS and Swift Charts

Weaknesses

Trace tooling needs Xcode's xctrace, so it works only on macOS
Focused on correctness and performance, gives no architecture or code-style guidance
SwiftUI only; concurrency, Core Data and testing are separate skills
Several reference files have no description in the README listing

What it needs

no GPU
Needs xctrace (Xcode), Python 3, Sosumi MCP (maintenance skill only)

How to choose

Check which agent it targets and whether it works with the version you run.
Read what it adds to every prompt; big rule sets cost tokens on each call.
