Latest swift changes

At WWDC 2024, several exciting updates were announced for Swift, particularly with the introduction of Swift 6. Here are some of the key changes and features:

1. Swift 6 Language Mode: Swift 6 introduces a new language mode that provides data race safety, enhancing Swift's safety guarantees for concurrent programming. This mode is opt-in, allowing developers to adopt it at their own pace and module by module.

2. Non-Copyable Types: Swift 6 introduces non-copyable types, which are a significant addition to the language, allowing for more efficient memory management and performance improvements.

3. Embedded Swift: A new language subset called Embedded Swift is introduced, designed to run on highly constrained systems, such as operating system kernels and microcontrollers.

4. Concurrency Improvements: There are enhancements to concurrency, including complete concurrency checking and improvements to data race checking, ensuring safer concurrent code.

5. Swift Testing Framework: A new testing framework named Swift Testing has been introduced, offering expressive APIs to simplify writing tests.

6. C++ Interoperability: Swift 6 continues to improve interoperability with C++, making it easier to integrate Swift with existing C++ codebases.

7. Typed Throws: This feature allows for more precise error handling in Swift, improving the robustness of error management in Swift applications.
