An asset can have multiple underlying data resources—for example, both original and edited versions—each of which is represented by a
PHAsset object. Unlike the
PHImage class, which provides and caches the primary representations of assets as thumbnails, image objects, or video objects, the asset resource manager provides direct access to these underlying data resources.
