Write Swift unit tests using Swift Testing (the modern Apple testing framework, not XCTest). Use this skill whenever the user asks to write tests, add test cases, create a test suite, or test a Swift type or function. Also triggers when the user asks to convert XCTest tests to Swift Testing, or when adding new tests to an existing XCTest-based file (always convert first). Invoke proactively when the user has just written a new Swift type or function and hasn't tested it yet.
