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. This year, Swift 6 introduces several new features and improvements.

Key Updates in Swift 6

  1. Data Race Safety: Swift 6 introduces a new language mode that ensures data race safety, expanding Swift's safety guarantees to concurrent programs.
  2. Embedded Swift: A new language subset called Embedded Swift is introduced, which can run on highly constrained systems.
  3. Non-Copyable Types: Swift 6 introduces non-copyable types, enhancing the language's ability to manage memory and resources more efficiently.
  4. C++ Interoperability: Improvements in interoperability with C++ make it easier to integrate Swift with existing C++ codebases.
  5. Typed Throws: Swift 6 introduces typed throws, allowing functions to specify the types of errors they can throw, improving error handling.
  6. Low-Level Synchronization Primitives: New primitives are introduced to help developers write more efficient concurrent code.

Swift Project Updates

  • GitHub Migration: The Swift project will be moving to a new organization on GitHub, swiftlang, which will include the Swift Compiler foundation and many more Swift ecosystem packages.
  • Swift Assist: A new tool called Swift Assist will be available later this year, enhancing the developer experience with predictive completion and other features.

Swift's Evolution

  • Swift Package Manager: Introduced in 2016, it has become a crucial tool for managing Swift projects.
  • Concurrency Model: Introduced async/await, actors, and structured concurrency, making it easier to write concurrent code.
  • SwiftUI: Leveraging Swift's unique features to build UI apps more efficiently.
  • Cross-Platform Support: Swift is now available on more platforms, including Windows and Linux.

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.
