# recognizedItems

An asynchronous array of items that the data scanner currently
recognizes in the camera’s live video.

```
@MainActor var recognizedItems: AsyncStream<[RecognizedItem]> { get }
```

## Discussion

You can use this property instead of the
[`DataScannerViewControllerDelegate`](/documentation/VisionKit/DataScannerViewControllerDelegate) protocol methods to track the
recognized items in real time. To get the changes between arrays, use
the
<doc://com.apple.documentation/documentation/Swift/Array/difference(from:)>
method. For more information on asynchronous streams, see
<doc://com.apple.documentation/documentation/Swift/concurrency>.

Text items in this array appear in the reading order of the language and
region.
