# virtualDeviceConstituentPhotoDeliveryEnabledDevices

The constituent devices for which the virtual device should deliver photos.

## Declaration

```swift
var virtualDeviceConstituentPhotoDeliveryEnabledDevices: [AVCaptureDevice] { get set }
```

## Discussion

Discussion You can opt in to constituent-device photo delivery by setting this property to any subset of the devices in the virtual device’s constituentDevices array. The framework calls your photoOutput(_:didFinishProcessingPhoto:error:)callback once for each of the devices you include in the array. You may only set this property to a non-nil array if you’ve set your photo output’s isVirtualDeviceConstituentPhotoDeliveryEnabled property to true, and your delegate implements the photoOutput(_:didFinishProcessingPhoto:error:) method. The default value of this property is an empty array.
