The question is around NSURLSession and NSURLSessionUploadTask.
I'm uploading large files to server and noticed that when I force quit the app the whole background upload just stops. However, when upload starts while app is running through the Xcode/debugger, then my upload completes just fine even when I stop the app running via Xcode 'stop' button. I suspect that force quitting the app using Xcode simulates an iOS system command and not a user action.
So my question is whether it's true that iOS would immediately cancel NSURLSessionUploadTask when user force quit the app?? For some reason I would at least expect an error callback to the app, however nothing happens.
