The Swift language has gone through many significant changes recently and this year is no different. We're now seeing some of the results of efforts to improve the approachability of data race safety. Many developers have found concurrency incredibly difficult to understand, making any improvements welcome. But, how can we use these new facilities to make our transition to Swift 6 easier?

We'll go through not just what new tools we have, but why they were introduced. Whether you are just now getting started or have lots of experience with concurrency, together we can deepen our understanding of the language. You'll come away feeling confident deciding how to best approach approachable concurrency for your project.

The foundation of Swift Concurrency's data race safety system is isolation. It is something many people struggle to understand, but using concurrency with success requires both a solid mental model as well as a command of the language features involved.

We're going to cover all forms of static isolation, learn what dynamic isolation is and when to use it. And, we'll also cover what Sendable is and how close a relationship it has with isolation. There will be an emphasis on approachable concurrency and how to understand and incorporate the newest language features.
