# AsyncPublisher

A publisher that exposes its elements as an asynchronous sequence.

## Declaration

```swift
struct AsyncPublisher<P> where P : Publisher, P.Failure == Never
```

## Overview

Overview AsyncPublisher conforms to AsyncSequence, which allows callers to receive values with the for-await-in syntax, rather than attaching a Subscriber. Use the values property of the Publisher protocol to wrap an existing publisher with an instance of this type.
