# device

The device for which the coordinator configures the preview layer.

## Declaration

```swift
weak var device: AVCaptureDevice? { get }
```

## Discussion

Discussion The value of this property is the AVCaptureDevice instance you provided when instantiating the configurator. AVCaptureExternalDisplayConfigurator holds a weak reference to the device. If the device is released, this property returns nil.
