Discussion
A burst photo sequence, as seen in the Photos app, corresponds to a group of Photos assets that share the same burstIdentifier string.
By default, the returned 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 object containing a filter predicate.
