I have developed an app for both Android and iOS. In the Android one I implemented the copy of PDF files downloaded from the app directly to Google Drive, with the user's authorization. The copy occurs automatically when the app downloads a new file, without user intervention. I wanted to know if something similar was possible on iOS, obviously not on Google Drive, as I would like to use the Apple cloud since many Apple users do not have a Google account. Which libraries can I use? I would like the thing to be as automated as possible, except of course the first authentication. Thanks
