where P : Publisher, P.Failure == Never ``` ## Overview `AsyncPublisher` conforms to , which allows callers to receive values with the `for`-`await`-`in` syntax, rather than attaching a [`Subscriber`](/documentation/Combine/Subscriber). Use the [`values`](/documentation/Combine/Publisher/values-1dm9r) property of the [`Publisher`](/documentation/Combine/Publisher) protocol to wrap an existing publisher with an instance of this type. ## Topics ### Creating an asynchronous publisher [`init(_:)`](/documentation/Combine/AsyncPublisher/init(_:)) Creates a publisher that exposes elements received from an upstream publisher as an asynchronous sequence. ### Creating an iterator [`makeAsyncIterator()`](/documentation/Combine/AsyncPublisher/makeAsyncIterator()) Creates the asynchronous iterator that produces elements of this asynchronous sequence. [`AsyncPublisher.Iterator`](/documentation/Combine/AsyncPublisher/Iterator) The iterator that produces elements of the asynchronous publisher sequence. ### Supporting types [`AsyncPublisher.Element`](/documentation/Combine/AsyncPublisher/Element) The type of element produced by this asynchronous sequence. --- Copyright © 2026 Apple Inc.
