For details, see [`PHFetchOptions`](/documentation/Photos/PHFetchOptions). ## Return Value A fetch result that contains the requested [`PHAsset`](/documentation/Photos/PHAsset) objects, or an empty fetch result if no objects match the request. ## Discussion A burst photo sequence, as seen in the Photos app, corresponds to a group of Photos assets that share the same [`burstIdentifier`](/documentation/Photos/PHAsset/burstIdentifier) string. By default, the returned [`PHFetchResult`](/documentation/Photos/PHFetchResult) object contains only the representative asset and any user-picked photos from the burst sequence. To retrieve all photos in the burst sequence, provide a [`PHFetchOptions`](/documentation/Photos/PHFetchOptions) object containing a filter predicate. --- Copyright © 2026 Apple Inc.
