It looks like you're interested in testing, particularly with Swift. Here are some key points and sessions from WWDC that cover various aspects of Swift testing:
-
Meet Swift Testing:
- Building blocks: This session introduces the fundamental components of Swift testing, including test functions, expectations, traits, and suites.
- Traits: Traits can add descriptive information, customize when or whether a test runs, or modify how a test behaves. Examples include display names, related bugs, custom tags, time limits, and execution order.
- Suites: Suites are used to group related test functions or other suites. They can be annotated explicitly using the suite attribute and can contain stored instance properties to avoid unintentional state sharing.
- Common workflows: This section covers tests with conditions, common characteristics, and different arguments.

Go further with Swift Testing:
- Organizing tests: This session discusses strategies to manage tests, including the use of suites and tags. Suites can now contain other suites, and tags help associate tests across different files, suites, and targets.
- Parameterized testing: This feature allows you to expand your test coverage by passing different inputs to a single test function. Each provided argument runs in parallel as its own test case.
- Testing in parallel: Parallel testing is enabled by default in Swift testing, allowing tests to run concurrently on all physical devices.

What’s new in Xcode 16:
- Test navigator: The test navigator in Xcode 16 has several new features to help you work with tagged tests. You can filter tests, group them by tags, and include or exclude tests from test plans.

These sessions provide a comprehensive overview of the new features and best practices for testing in Swift. If you have any specific questions or need timestamps for particular topics, feel free to ask!

What’s new in Xcode 16
Discover the latest productivity and performance improvements in Xcode 16. Learn about enhancements to code completion, diagnostics, and Xcode Previews. Find out more about updates in builds and explore improvements in debugging and Instruments.

Meet Swift Testing
Introducing Swift Testing: a new package for testing your code using Swift. Explore the building blocks of its powerful new API, discover how it can be applied in common testing workflows, and learn how it relates to XCTest and open source Swift.

Go further with Swift Testing
Learn how to write a sweet set of (test) suites using Swift Testing’s baked-in features. Discover how to take the building blocks further and use them to help expand tests to cover more scenarios, organize your tests across different suites, and optimize your tests to run in parallel.
