# queue

The queue on which to execute recognition task handlers and delegate methods.

## Declaration

```swift
var queue: OperationQueue { get set }
```

## Discussion

Discussion The default value of this property is the app’s main queue. Assign a different queue if you want delegate methods and handlers to be executed on a background queue. The handler you pass to the requestAuthorization(_:) method does not use this queue.
