What's New for Swift at WWDC 2024

Swift's Evolution and Features

Swift continues to evolve, celebrating its 10th birthday this year. It remains a compelling choice for performance-sensitive and secure code, thanks to its safety, speed, and approachability. Swift's built-in C and C++ interoperability further solidifies its position as a successor to C, enabling developers to express what they want without worrying about the underlying implementation details.

SwiftUI Enhancements

SwiftUI has seen significant updates, making it easier to build user interfaces across all Apple devices. Key improvements include:

  • Custom Containers and Mesh Gradients: New features for fine-tuning the look and feel of apps.
  • Scrolling Customizations: Enhanced control over scrolling behavior.
  • Interoperability: Improved integration with UIKit and AppKit, allowing for seamless use of gestures and animations across different frameworks.

Swift Testing and Data

Swift has introduced new testing APIs designed to be more productive and easier to use. Additionally, Swift Data helps model and persist app information using a lightweight API that feels natural in Swift.

Swift Assist

A new feature called Swift Assist has been introduced, acting as a companion for coding tasks. It can answer coding questions and help with experimenting with new APIs, making it easier to explore new frameworks and ideas.

Swift 6 Language Mode

The new Swift 6 language mode is opt-in, offering compile-time checking and other enhancements. This mode includes:

  • Main Actor Annotation: All types conforming to View are implicitly isolated to the main actor by default.
  • Improved Interoperability: Significant improvements in the integration of gestures and animations with UIKit and AppKit.

Xcode and Developer Experience

Xcode 16 introduces several new features to improve productivity and app quality, such as:

  • Single View of Backtraces
  • Flame Graphs in Instruments
  • Enhancements to Localization Catalogs
