1. Meet Swift Testing:

   • This session provides an in-depth look at the new Swift testing framework, comparing it to XCTest and explaining its features, such as the @test attribute, expect and require macros, and support for traits and parallelization.
   • Meet Swift Testing (17:35)

2. Platforms State of the Union:

   • This session introduces Swift testing as a new framework built from the ground up for Swift, highlighting its expressive APIs, cross-platform capabilities, and open-source nature.
   • Platforms State of the Union (33:01)

3. What’s new in Xcode 16:

   • This session demonstrates how Swift testing is integrated into Xcode 16, showing how to create and run tests using the new framework.
   • What’s new in Xcode 16 (12:55)

4. What’s new in Swift:

   • This session explores the features of Swift testing, including the @test attribute, custom display names, tags for organizing tests, and parameterized tests.
