what is new in swift in 2024?

In 2024, Swift introduced several significant updates and new features. Here are the key highlights:

1. Swift 6 Language Mode:

   • Data Race Safety: Swift 6 introduces a new language mode that ensures data race safety, expanding Swift's safety guarantees to concurrent programs. This helps developers write correct concurrent programs by providing data race checking and complete concurrency checking.
   • Non-Copyable Types: Swift 6 introduces non-copyable types, which means that not all Swift types are copyable by default. This can help optimize performance and memory usage.

2. Embedded Swift:

   • A new language subset called Embedded Swift is introduced, which can run on highly constrained systems, making Swift more versatile for different types of hardware.

3. Swift's New Space on GitHub:

   • The Swift project is moving to a new organization on GitHub (swiftlang), which will include the Swift Compiler foundation and many more Swift ecosystem packages.

4. Interoperability:

   • Continued improvements in interoperability, including bi-directional interoperability with C, making it easier to integrate Swift with existing C codebases.

5. SwiftUI Enhancements:

   • SwiftUI has gained new customizations to fine-tune the look and feel of apps, and it now supports setting up animations on UIKit or AppKit views, which can be driven with SwiftUI.

6. Swift Testing APIs:

   • New Swift testing APIs have been designed to be dramatically easier to use, making developers more productive.

7. Swift Data:

   • Swift Data helps model and persist app information using a lightweight API that feels natural in Swift.
