Unlocking the Power of Swift Testing: Modern Approaches to Testing iOS Apps

" summary

Swift Testing is a new open‑source package that replaces many XCTAssert variants with a single expect macro, adds parameterized testing and suites/traits/tags for grouping, and runs on all Swift platforms; migration is gradual (requires Xcode 16+) and often quick for simple tests. Real projects show cleaner names, fewer helper loops, and one line per assertion, but testing legacy closures and Combine publishers needs continuations or a continuation wrapper (extra boilerplate), and UI interaction still relies on XCUITest.
