prefetchAssetExtendedMetadata
A Boolean value to fetch PHAssetExtendedMetadata when the asset is also fetched.
Declaration
var prefetchAssetExtendedMetadata: Bool { get set }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.
