# values The elements produced by the publisher, as a throwing asynchronous sequence. ``` var values: AsyncThrowingPublisher { get } ``` ## Discussion This property provides an [`AsyncThrowingPublisher`](/documentation/Combine/AsyncThrowingPublisher), which allows you to use the Swift `async`-`await` syntax to receive the publisher’s elements. Because [`AsyncPublisher`](/documentation/Combine/AsyncPublisher) conforms to , you iterate over its elements with a `for`-`await`-`in` loop, rather than attaching a subscriber. If the publisher terminates with an error, the awaiting caller receives the error as a `throw`. The following example shows how to use the `values` property to receive elements asynchronously. The example adapts a code snippet from the [`tryFilter(_:)`](/documentation/Combine/Publisher/tryFilter(_:)) operator’s documentation, which filters a sequence to only emit even integers, and terminate with an error on a `0`. This example replaces the [`Subscribers.Sink`](/documentation/Combine/Subscribers/Sink) subscriber with a `for`-`await`-`in` loop that iterates over the [`AsyncPublisher`](/documentation/Combine/AsyncPublisher) provided by the `values` property. With this approach, the error handling previously provided in the sink subscriber’s [`receiveCompletion`](/documentation/Combine/Subscribers/Sink/receiveCompletion) closure goes instead in a `catch` block. ``` let numbers: [Int] = [1, 2, 3, 4, 0, 5] let filterPublisher = numbers.publisher .tryFilter{ if $0 == 0 { throw ZeroError() } else { return $0 % 2 == 0 } } do { for try await number in filterPublisher.values { print ("\(number)", terminator: " ") } } catch { print ("\(error)") } ``` --- Copyright © 2026 Apple Inc.
