# focusTrackedObject

An identifier for an instance of AVMetadataFocusTrackedObject.

## Declaration

```swift
static let focusTrackedObject: AVMetadataObject.ObjectType
```

## Discussion

Discussion This metadata object type is only available when the source AVCaptureDevice’s activeFormat has AVCaptureDeviceFormat/isContinuousAutoFocusTrackingSupported equal to true. It can therefore appear and disappear from availableMetadataObjectTypes as the active format changes; observers should not assume it is statically available for the lifetime of the session.
