I wish to download large file (about: 500MB) from server. The server is implemented by us server with gRPC command that works as follows. The user request for file and then the app receives byte stream which added to file. In Android I am using background persistent notification with service, and opening new thread on this service until the download completes. The user can exit the app and the OS will not kill persistent notification service.
What is the equivalent for background downloading for iOS. I checked the URLSessionDownloadTask but I do not think it will work with gRPC.
What is your solution for downloading big data with iOS?
