# PHImageRequestOptionsDeliveryMode.highQualityFormat

Photos provides only the highest-quality image available, regardless of how much time it takes to load.

## Declaration

```swift
case highQualityFormat
```

## Discussion

Discussion If the isSynchronous property is true or if using the requestImageDataForAsset:options:resultHandler: method, this behavior is the default and only option (that is, specifying other delivery mode options has no effect).
