Xcode Playgrounds do not directly support XCTest, as they are primarily designed for interactive coding and learning rather than full-scale application testing. However, you can use Xcode to write and run tests using XCTest or the new Swift Testing framework.
In the session Meet Swift Testing, it is explained how Swift Testing and XCTest relate to one another. Swift Testing introduces a new approach with features like traits for specifying information per test or suite, and it uses Swift concurrency for parallelization. It also simplifies assertions with just two basic macros, expect and require, instead of the many XCTAssert functions used in XCTest.
For more details on Swift Testing and its integration with Xcode, you can refer to the session Meet Swift Testing.
What’s new in Swift
Join us for an update on Swift. We’ll briefly go through a history of Swift over the past decade, and show you how the community has grown through workgroups, expanded the package ecosystem, and increased platform support. We’ll introduce you to a new language mode that achieves data-race safety by default, and a language subset that lets you run Swift on highly constrained systems. We’ll also explore some language updates including noncopyable types, typed throws, and improved C++ interoperability.
