# prefetchAssetExtendedMetadata

A Boolean value to fetch PHAssetExtendedMetadata when the asset is also fetched.

## Declaration

```swift
var prefetchAssetExtendedMetadata: Bool { get set }
```

## Discussion

Discussion By default extendedMetadata is fetched on demand, with the dot accessor. Prefetching will fetch it as part of the PHAsset in a single fetch, rather than incurring fetch overhead for each PHAsset.
