Swift does not provide a built-in way of converting an AsyncSequence into a regular Sequence, but often you’ll want to make this conversion yourself so you don’t n...

AsyncStream and AsyncThrowingStream can be thought of a bit like continuations that can send back multiple values, but also like an AsyncSequence that is a...

Async/await Sequences and streams Tasks and task groups Actors Testing Solutions

Using async/await in Swift allows us to write asynchronous code that is easy to read and understand, but by itself it doesn’t enable us to run anything concurrently – even w...

Swift’s Task struct lets us start running some work immediately, and optionally wait for the result to be returned. And it is optional: sometimes you don’t ca...

If you create a new task using the regular Task initializer, your work starts running immediately and inherits the priority of the caller, any task local values, and its ...

Swift’s Task struct has a static sleep() method that will cause the current task to be suspended for a set period of time. You need to call Task.sleep()&n...

If you want to read the return value from a Task directly, you should read its value using await, or use try await if it has a throwing operation...

Swift tasks can have a priority attached to them, such as .high or .background, but the priority can also be nil if no specific priority was assigned. This...

Every task can be created with a specific priority level, or it can inherit a priority from somewhere else. But in two specific circumstances, Swift will raise the priori...
