Write and migrate modern unit tests using the Swift Testing framework for iOS, macOS, and Swift 6+ projects.
The Swift Testing skill provides specialized guidance for implementing Apple's modern testing framework (Xcode 16+, Swift 6+). It helps developers transition from XCTest to a macro-based testing approach, utilizing features like @Test, @Suite, and parameterized testing. This skill ensures your test suites are expressive, performant, and correctly structured by leveraging Swift's native concurrency, traits for conditional execution, and sophisticated validation macros. Whether you are refactoring legacy suites or building new asynchronous test patterns with actor isolation, this skill provides the implementation patterns and best practices required for robust Apple platform development.
