## AI overview

This tutorial introduces Swift Testing, the modern Swift testing framework built around expressive macros such as @Test, #expect, and #require. It explains how Swift Testing replaces XCTest, reduces repetitive boilerplate, defines tests globally, and organizes them with structs, traits, and tags.

## Source excerpt

It's the successor to XCTest and the default testing framework for new projects in Xcode. Instead of dozens of assertion methods, you work with a single expressive macro that tells you exactly why a test ... -> The post Swift Testing explained with code examples appeared first on SwiftLee.
