Async/await is a concurrency model used in Swift to handle asynchronous operations. When a function might suspend its execution to wait for an asynchronous operation to complete, it is marked with the async keyword. When calling an async function, the await keyword is used to indicate that the function may suspend at that point, allowing other tasks to use the CPU while waiting.
This model is particularly useful for operations like reading from a disk or messaging another service, where waiting for a response is necessary. By using async/await, Swift can efficiently manage task suspension and resumption, improving the performance and responsiveness of applications.
For more details, you can refer to the session A Swift Tour: Explore Swift’s features and design (19:10) where async/await is discussed in the context of Swift's concurrency features.
Explore Swift performance
Discover how Swift balances abstraction and performance. Learn what elements of performance to consider and how the Swift optimizer affects them. Explore the different features of Swift and how they’re implemented to further understand the tradeoffs available that can impact performance.
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.
Go further with Swift Testing
Learn how to write a sweet set of (test) suites using Swift Testing’s baked-in features. Discover how to take the building blocks further and use them to help expand tests to cover more scenarios, organize your tests across different suites, and optimize your tests to run in parallel.
