Does this skill support legacy XCTest?

While the focus is on the modern Swift Testing framework, it provides comprehensive comparison tables and migration paths for transitioning from XCTest to the new syntax.

What are the key benefits of Swift Testing over XCTest?

Swift Testing uses traits for metadata, supports value types (structs) for test suites, provides more descriptive macro-based expectations, and offers built-in support for parameterized testing.

Can I use this skill for UI Testing?

No, Apple currently requires XCTest and XCUIApplication for UI testing. This skill is specifically designed for unit and integration testing using the Swift Testing framework.

Does it handle asynchronous code?

Yes, it includes specific patterns for testing async/await code, actor state, and 'confirmation' patterns for testing callbacks and events.

Mobile Development

Implements modern Swift Testing framework patterns and best practices for iOS and macOS development.

概要

This skill equips Claude with specialized knowledge of the modern Swift Testing framework introduced at WWDC 2024. It enables the creation of robust, declarative unit tests using the latest Apple standards, moving beyond legacy XCTest patterns. Whether you are building new test suites from scratch or migrating existing projects to Xcode 16, this skill provides precise guidance on expectations, suites, parameterized testing, and asynchronous confirmation patterns to ensure high-quality Swift codebases.
