Most discussed new Swift/iOS features presented on the last WWDC

At the latest WWDC, several new features and improvements for Swift and iOS were highlighted. Here are some of the most discussed updates:

1. SwiftUI Enhancements:

   • Rich Text Editing: SwiftUI now supports rich text editing by changing the binding of a text editor's text from a string to an attributed string, allowing for fully customizable styling (Platforms State of the Union).
   • 3D Charts: Swift Charts now supports 3D, thanks to RealityKit, allowing for interactive camera controls to rotate and zoom (Platforms State of the Union).
   • Scrolling Enhancements: New APIs provide fine-grained control over scroll views, including detecting visibility changes due to scrolling (What’s new in SwiftUI).

2. Swift Language Updates:

   • Concurrency Improvements: Continued refinement of the concurrency model with async/await and structured concurrency (What’s new in Swift).
   • Swift 6 Language Mode: Introduces compile-time data race safety, making concurrency more approachable (What’s new in SwiftUI).

3. Xcode and Developer Tools:

   • Xcode Previews: A new dynamic linking architecture for smoother and more productive workflows (Platforms State of the Union).
   • Swift Assist: A new tool to help developers interact with code using natural language, integrated with advanced coding models like ChatGPT (Keynote).

4. Performance Improvements:

   • SwiftUI Performance: Significant improvements in scrolling performance and list updates, with incremental changes up to 16 times faster (Platforms State of the Union).

These updates reflect Apple's ongoing efforts to enhance the developer experience and improve the performance and capabilities of apps across all Apple platforms.
