A delegate that Photos calls after loading the asset’s data and preparing the export session.

exportSession: An AVAssetExportSessionMBS object that you can use for writing the video asset’s data to a file.
info: A dictionary that provides information about the status of the request. See Image Result Info Keys for possible keys and values.

We pass AVAsset, the AVAssetExportSessionMBS object, as variant to avoid plugin dependencies.
