This skill writes and reviews Swift Testing code against the latest APIs and conventions. It helps Apple platform developers, test automation engineers, and library maintainers bring test suites up to date with Swift 6.2 and modern concurrency. The review process checks structure, assertions, async testing, and migration from XCTest, then prioritizes the most impactful fixes.
Follow the documented setup, then try a first task.

Installs: Installs the swift-testing-pro skill after adding the documented Node dependency; during skill installation, the user can select specific agents and choose project-only or all-project availability. · Codex, Gemini, Cursor, others
If the skill-install command fails with `npx: command not found`, run this command in a terminal to install Node through Homebrew. If Homebrew itself is unavailable, install it first using the linked Homebrew documentation; no Homebrew installer command is supplied in the evidence.
brew install node
After Node is installed, run this command in a terminal. During the interactive installation, select the desired agents and whether installation should apply to one project or all projects.
