# requestMetadata()

Requests metadata for the item.

## Declaration

```swift
func requestMetadata()
```

## Discussion

Discussion If metadata for the item is not readily available, accessing this property requests metadata from the camera, then notifies the delegate by calling cameraDevice(_:didReceiveMetadata:for:error:). Execution of the delegate callback occurs on the main thread.
