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...

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...

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...

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...

There are only three differences between creating an AsyncSequence and creating a regular Sequence, none of which are complicated.创建 AsyncSequence 和创建...

AsyncSequence has implementations of many of the same methods that come with Sequence, but how they operate varies: some return a single value that fulfills you...

You can loop over an AsyncSequence using Swift’s regular loop types, for, while, and repeat, but whenever you read a value from the async sequence you mus...

Swift provides several ways of receiving a potentially endless flow of data, allowing us to read values one by one, or loop over them using for, while, or similar.Swift ...

This error occurs when you’ve tried to call an async function from a synchronous function, which is not allowed in Swift – asynchronous functions must be able to suspend the...
