Swift Testing

A compact reference for Apple's Swift Testing framework that shipped with iOS 26 and later. You get local docs for the core stuff: @Test and @Suite macros, #expect and #require assertions, parameterized tests, traits like tags and time limits, plus a migration guide if you're coming from XCTest. The skill prioritizes searching local markdown files before fetching anything new, which keeps your context window cleaner. If you're writing tests in modern Swift projects and want the API details without leaving your editor, this covers the essentials in a queryable format.
