what are the new swift features

Here are some of the new features introduced in Swift at WWDC 2024:

1. Swift 6 Language Mode:

   • Data Race Safety: Swift 6 introduces a new language mode that achieves data race safety, expanding Swift's safety guarantees to concurrent programs. This helps in writing correct concurrent programs (What’s new in Swift).
   • Non-Copyable Types: Swift 6 introduces non-copyable types, which means that all Swift types, whether value types or reference types, are copyable by default, but you can now define types that cannot be copied (What’s new in Swift).

2. Embedded Swift:

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

3. C++ Interoperability:

   • Swift 6 includes improvements for interoperability with C++, making it easier to integrate Swift with C++ codebases (What’s new in Swift).

4. Typed Throws:

   • Swift 6 introduces typed throws, allowing functions to specify the types of errors they can throw (What’s new in Swift).

5. Low-Level Synchronization Primitives:

   • New low-level synchronization primitives are introduced to provide more control over concurrent programming (What’s new in Swift).

6. Swift Assist:

   • A new feature called Swift Assist is introduced, which will be available later this year. It includes predictive completion for Apple Silicon Macs (Platforms State of the Union).

7. SwiftUI Enhancements:

   • SwiftUI has gained several new features, including custom containers, mesh gradients, scrolling customizations, and the ability to set up animations on UIKit or AppKit views and drive them with SwiftUI (Platforms State of the Union).
