# values

The elements produced by the publisher, as a throwing asynchronous sequence.

## Declaration

```swift
var values: AsyncThrowingPublisher<Self> { get }
```

## Discussion

Discussion This property provides an AsyncThrowingPublisher, which allows you to use the Swift async-await syntax to receive the publisher’s elements. Because AsyncPublisher conforms to AsyncSequence, 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(_:) 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 subscriber with a for-await-in loop that iterates over the AsyncPublisher provided by the values property. With this approach, the error handling previously provided in the sink subscriber’s 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)") }
