The "sea of concurrency" refers to the complexities and challenges associated with managing concurrent programming, particularly in the context of Swift. At WWDC 2024, several sessions addressed these challenges and introduced new features in Swift 6 to improve concurrency management and data race safety.
-
Swift 6 Language Mode and Data-Race Safety: Swift 6 introduces data race safety by default, turning potential data race issues into compile-time errors. This significantly enhances the security and reliability of applications by preventing unexpected runtime behavior and crashes due to data races. What's new in Swift.
-
Concurrency Features in Swift: Swift's concurrency model includes actors, async/await, and sendable types to manage shared mutable state safely. Actors are used to encapsulate state and ensure that only one task can access the state at a time, preventing data races. A Swift Tour: Explore Swift’s features and design.
-
Migrating to Swift 6: The session on migrating apps to Swift 6 discusses the transition from ad-hoc concurrency architectures to structured concurrency using Swift's new features. This includes setting UI views and models to run on the main actor and using dedicated actors for background operations. Migrate your app to Swift 6.
These sessions collectively highlight the advancements in Swift 6 that aim to simplify concurrency management and enhance the safety and performance of Swift applications.
What’s new in Swift
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.
Migrate your app to Swift 6
Experience Swift 6 migration in action as we update an existing sample app. Learn how to migrate incrementally, module by module, and how the compiler helps you identify code that’s at risk of data races. Discover different techniques for ensuring clear isolation boundaries and eliminating concurrent access to shared mutable state.
A Swift Tour: Explore Swift’s features and design
Learn the essential features and design philosophy of the Swift programming language. We’ll explore how to model data, handle errors, use protocols, write concurrent code, and more while building up a Swift package that has a library, an HTTP server, and a command line client. Whether you’re just beginning your Swift journey or have been with us from the start, this talk will help you get the most out of the language.
