Swift Updates at WWDC 2024

Key Updates in Swift 6

1. New Language Mode:

   • Swift 6 introduces a new language mode that achieves data-race safety, expanding Swift's safety guarantees to concurrent programs. This mode can be adopted module by module, allowing for incremental migration (What’s new in Swift).

2. Non-Copyable Types:

   • Swift 6 introduces non-copyable types, which are not copyable by default. This is a significant change from previous versions where all Swift types were copyable (What’s new in Swift).

3. Embedded Swift:

   • A new language subset called Embedded Swift is introduced, which can run on highly constrained systems like operating system kernels and microcontrollers (What’s new in Swift).

4. Concurrency Improvements:

   • Significant improvements to concurrency, including complete concurrency checking in Swift 5.10 and enhancements in Swift 6 to recognize safe scenarios for passing non-sendable values across isolation boundaries (What’s new in Swift).

5. Swift Testing:

   • Introduction of a new testing framework called Swift Testing, built from the ground up for Swift. It features expressive APIs that simplify writing tests (Platforms State of the Union).

6. Swift Data:

   • Enhancements to Swift Data, including expanded capabilities for data storage and change tracking, support for custom data stores, and new syntax additions like index and unique (Platforms State of the Union).

7. Swift's New Space on GitHub:

   • The Swift project will be moving to a new organization on GitHub (swiftlang) and will be managed by the Swift project. This includes the Swift Compiler foundation and many more Swift ecosystem packages (What’s new in Swift).
