Code-along: Elevate an app with Swift concurrency — WWDC 2025

About this session

Learn how to optimize your app's user experience with Swift concurrency as we update an existing sample app. We'll start with a main-actor app, then gradually introduce asynchronous code as we need to. We'll use tasks to optimize code running on the main actor, and discover how to parallelize code by offloading work to the background. We'll explore what data-race safety provides, and work through interpreting and fixing data-race safety errors. Finally, we'll show how you can make the most out of structured concurrency in the context of an app.
