### Description https://github.com/firebase/firebase-ios-sdk/blob/master/FirebaseStorage/Sources/AsyncAwait.swift In this file we emit StorageUploadTask, and we can't add observers, so we don't know about the progress. (e.g. putFileAsync) Uploading large files difficult to handle without knowing status ### API Proposal Perhaps you can add delegate and handle all observers inside, then tell that something is changed to delegate? ### Firebase Product(s) Storage
