Structured concurrency in Swift is a programming model that helps manage concurrent tasks in a more organized and predictable manner. It is designed to simplify the complexity of concurrent programming by providing clear and structured ways to define and manage tasks, ensuring that they are executed in a safe and efficient manner.
In Swift, structured concurrency is achieved through features like async/await and actors. These features allow developers to write asynchronous code that is easier to read and maintain, while also providing safety guarantees against data races. The Swift concurrency model ensures that data races, which can occur when multiple threads access shared data simultaneously, are caught at compile time, reducing runtime errors and improving the overall reliability of applications.
For more detailed information on structured concurrency, you can refer to the session A Swift Tour: Explore Swift’s features and design at the 18:33 mark, which covers concurrency in Swift.
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.
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.
What’s new in Xcode 16
Discover the latest productivity and performance improvements in Xcode 16. Learn about enhancements to code completion, diagnostics, and Xcode Previews. Find out more about updates in builds and explore improvements in debugging and Instruments.
