swift new in 2024

In 2024, Swift introduced several significant updates and features, particularly with the release of Swift 6. Here are some of the key 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 and interoperate with dependencies that may not have migrated yet.

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, expanding Swift's applicability to more platforms.

4. C++ Interoperability: Continued improvements in interoperability with C++ make it easier to integrate Swift with existing C++ codebases.

5. Concurrency Improvements: Swift 6 builds on previous concurrency models by introducing data race safety, which diagnoses potential data races at compile time, making concurrent programming safer and more reliable.

6. Swift's New Space on GitHub: The Swift project is moving to a new organization on GitHub, which will include the Swift Compiler foundation and other ecosystem packages, fostering better collaboration and development.
