Major Swift Changes at WWDC 2024

At WWDC 2024, several significant updates and features were introduced for the Swift programming language:

1. Swift 6 Language Mode:

   • Swift 6 introduces a new language mode that provides compile-time data race safety, which is opt-in. This mode allows developers to diagnose and fix concurrent access to memory, enhancing the safety of concurrent programs. You can migrate to Swift 6 incrementally, one module at a time, without waiting for dependencies to migrate. Platforms State of the Union

2. Non-Copyable Types:

   • Swift 6 introduces non-copyable types, which are a new feature that allows developers to define types that cannot be copied. This is particularly useful for managing resources and ensuring data integrity in concurrent programming. What’s new in Swift

3. Embedded Swift:

   • A new language subset called Embedded Swift is introduced, which can run on highly constrained systems, expanding Swift's applicability to more environments. What’s new in Swift

4. C++ Interoperability:

   • Enhancements in interoperability with C++ were discussed, making it easier to integrate Swift with existing C++ codebases. What’s new in Swift

5. Typed Throws:

   • Swift 6 introduces typed throws, allowing functions to specify the types of errors they can throw, improving error handling and code clarity. What’s new in Swift

6. Community and Ecosystem Updates:

   • The Swift community continues to grow, with new steering groups and workgroups focusing on different aspects of the language and its ecosystem. A new platform steering group was introduced to bring Swift to more places, and an ecosystem steering group is being created to focus on the developer experience. What’s new in Swift

These updates reflect Swift's ongoing evolution to enhance performance, safety, and developer experience across various platforms and use cases.
