What's New in Swift

Overview

Swift has reached a significant milestone, celebrating its 10th anniversary. Over the years, Swift has evolved to become a powerful, safe, and expressive programming language, suitable for a wide range of applications from app development to system programming.

Key Updates in Swift 6

  1. New Language Mode: Swift 6 introduces a new language mode that provides data race safety, enhancing the safety guarantees for concurrent programs.
  2. Non-Copyable Types: Swift 6 introduces non-copyable types, which are not copyable by default, providing more control over memory management.
  3. Embedded Swift: A new language subset called Embedded Swift is introduced, designed to run on highly constrained systems.
  4. Concurrency Improvements: Significant improvements in data race checking and concurrency model, including complete concurrency checking in Swift 5.10.
  5. C++ Interoperability: Enhanced interoperability with C++, making it easier to integrate Swift with existing C++ codebases.
  6. Typed Throws: Introduction of typed throws, allowing functions to specify the types of errors they can throw.
  7. Low-Level Synchronization Primitives: New primitives for low-level synchronization, providing more tools for concurrent programming.

Swift Ecosystem

  • Swift Package Manager: Continues to evolve, supporting a wide range of packages and tools.
  • Cross-Platform Development: Swift is now available on more platforms, including Windows and Linux, with cross-compilation support.
  • Swift Testing: New testing APIs designed for Swift, making it easier to write and maintain tests.

SwiftUI Integration

  • Swift 6 Language Mode: SwiftUI has improved its APIs to make it easier to adopt the new language mode in your apps.
  • Main Actor Isolation: Views in SwiftUI are now evaluated on the main actor, ensuring thread safety by default.

Community and Future Directions

  • GitHub Migration: The Swift project will be moving to a new organization on GitHub, managed by the Swift project.
  • Community Contributions: The community continues to play a vital role in the evolution of Swift, contributing to its growth and development.

Join us for an update on Swift. We’ll briefly go through a history of Swift over the past decade, and show you how the community has grown through workgroups, expanded the package ecosystem, and increased platform support. We’ll introduce you to a new language mode that achieves data-race safety by default, and a language subset that lets you run Swift on highly constrained systems. We’ll also explore some language updates including noncopyable types, typed throws, and improved C++ interoperability.
