FAQPage Schema
How do I migrate from XCTest to Swift Testing?

Migrating from XCTest to Swift Testing involves converting existing XCTestCase classes into modern Swift Testing suites using @Suite and @Test macros. This skill provides comprehensive API documentation and guides to transition setup and teardown logic to the new framework.

What is the best way to write parameterized tests in Swift?

The best way to write parameterized tests in Swift is using the Swift Testing framework. It supports parameterized test cases natively, allowing developers to run the same test logic across multiple inputs to improve test coverage and reduce boilerplate.

How do I use #expect and #require macros in Swift Testing?

You use #expect and #require macros in Swift Testing to validate conditions during unit tests. #expect checks conditions and records failures, while #require stops test execution immediately upon failure, providing modern expressive syntax for iOS 26+ applications.

Can I run concurrent unit tests with Swift Testing for iOS applications?

Yes, you can run concurrent unit tests with Swift Testing for iOS applications. The framework enables developers to implement robust, concurrent, and expressive unit tests, improving execution efficiency for iOS 26+ applications.

Does Swift Testing support asynchronous event confirmation?

Yes, Swift Testing supports asynchronous event confirmation. The framework includes advanced testing capabilities that allow developers to confirm asynchronous events, ensuring robust validation for modern concurrent Swift applications.
