What's new in latest Swift

In the latest updates presented at WWDC 2024, Swift has introduced several new features and improvements. Here are some of the highlights:

1. Swift 6 Language Mode: Swift 6 introduces a new language mode that provides data race safety, expanding Swift's safety guarantees to concurrent programs. This is a significant step in ensuring code safety and maintainability.

2. Embedded Swift: A new language subset called Embedded Swift has been introduced, which can run on highly constrained systems like operating system kernels and microcontrollers.

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

4. Concurrency Improvements: There have been significant improvements to concurrency, including better data race checking and enhancements to generics.

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

6. C++ Interoperability: Enhancements have been made to improve interoperability with C++, making it easier to integrate Swift with existing C++ codebases.

7. Swift's 10th Anniversary: This year marks the 10th anniversary of Swift, highlighting its evolution and the community's contributions to its growth.
