# replacementDepthData(for:)

A callback in which you can provide replacement depth data or strip existing depth data from the file.

## Declaration

```swift
optional func replacementDepthData(for photo: AVCapturePhoto) -> AVDepthData?
```

## Parameters

- `photo`: The calling instance of doc://com.apple.avfoundation/documentation/AVFoundation/AVCapturePhoto whose file metadata you’re modifying.

## Return Value

Return Value An instance of AVDepthData.  To preserve the existing depth data, return photo.depthData. To strip existing depth data, provide a replacement AVDepthData instance.

## Discussion

Discussion This callback is optional. If your delegate doesn’t implement this callback, the existing metadata in the in-memory AVCapturePhoto container is written directly to the file data representation.
