# progressHandler

A block that Photos calls periodically while downloading the Live Photo.

## Declaration

```swift
var progressHandler: PHAssetImageProgressHandler? { get set }
```

## Discussion

Discussion If you request a Live Photo whose data is not on the local device, and you have enabled downloading with the PHLivePhotoRequestOptions property, Photos calls your block periodically to report progress and to allow you to cancel the download.
