At WWDC 2024, several new features and improvements were introduced for Swift, particularly with the release of Swift 6. Here are some of the highlights:

  1. Swift 6 Language Mode: Swift 6 introduces a new language mode that provides data race safety, which helps in writing correct concurrent programs. This mode is opt-in, allowing developers to adopt it module by module.

  2. Non-Copyable Types: Swift 6 introduces non-copyable types, which enhance the language's ability to manage memory and resources more efficiently.

  3. Embedded Swift: A new language subset called Embedded Swift is introduced, which is designed to run on highly constrained systems.

  4. Concurrency Improvements: Swift 6 continues to build on its concurrency model with improvements in data race checking and the introduction of low-level synchronization primitives.

  5. C++ Interoperability: Enhancements in interoperability with C++ allow for more seamless integration between Swift and C++ codebases.

  6. Typed Throws: This feature provides more precise error handling by allowing functions to specify the types of errors they can throw.

For more detailed information, you can refer to the session What’s new in Swift (17:03) which covers these updates extensively.
