I'm having an issue with showing progress in a upload task. I have created a local express app to test it's behavior. But progress / delegate always throughs the same results. I'm also conforming to URLSessionTaskDelegate. This is the way I configure URLSession it's always .default private lazy var session: URLSession = { .init( configuration: self.configuration, delegate: self, delegateQueue: OperationQueue.main ) }() private var observation: NSKeyValueObservation? Then I call it using this func and convert it into a publisher func loadData1(path: String, method: RequestMethod, params: [String: String]) -> AnyPublisher<Data, Error> { let publisher = PassthroughSubject<Data, Error>() guard let imageUrl = Bundle.main.url(forResource: "G0056773", withExtension: "JPG"), let imageData = try? Data(contentsOf: imageUrl) else { return Fail(error: NSError(domain: "com.test.main", code: 1000)).eraseToAnyPublisher() } var request = URLRequest(url: URL(string: "http://localhost:3000/")!) request.httpMethod = "POST" let data = request.createFileUploadBody(parameters: [:], boundary: UUID().uuidString, data: imageData, mimeType: "image/jpeg", fileName: "video") let task = session.uploadTask(with: request, from: data) { data, response, error in if let error = error { return publisher.send(completion: .failure(error)) } guard let response = response as? HTTPURLResponse else { return publisher.send(completion: .failure(ServiceError.other)) } guard 200..<300 ~= response.statusCode else { return publisher.send(completion: .failure(ServiceError.other)) } guard let data = data else { return publisher.send(completion: .failure(ServiceError.custom("No data"))) } return publisher.send(data) } observation = task.progress.observe(\.fractionCompleted) { progress, _ in print("progress: ", progress.totalUnitCount) print("progress: ", progress.completedUnitCount) print("progress: ", progress.fractionCompleted) print("***********************************************") } task.resume() return publisher.eraseToAnyPublisher() } request.createFileUploadBody is just an extension of URLRequest that I have created to create the form data's body. Delegate func urlSession(_ session: URLSession, task: URLSessionTask, didSendBodyData bytesSent: Int64, totalBytesSent: Int64, totalBytesExpectedToSend: Int64) { print(bytesSent) print(totalBytesSent) print(totalBytesExpectedToSend) print("*********************************************") } No matter how big or small is the file that I'm uploading I always get the same results. The delegate is only called once. And the progress is also always the same. progress: 100 progress: 0 progress: 0.0095 *********************************************** progress: 100 progress: 0 progress: 4.18053577746524e-07 *********************************************** 2272436 2272436 2272436 ********************************************* progress: 100 progress: 95 progress: 0.95 *********************************************** progress: 100 progress: 100 progress: 1.0 *********************************************** ^^^^^^ Output from prints Does anyone knows what might I be doing wrong? Thanks in advance

Hi! I'm dropping a pdf file in an app, and I'm getting 2 errors I cannot understand. When I drop the file I'm supposed to create a pdf view, which, by the way I can. I perform the drop th in a swiftui view.             GeometryReader { geometry in                 ZStack {                     Rectangle()                         .foregroundColor(.white)                         .overlay(OptionalPDFView(pdfDocument: self.document.backgroundPDF))                                     }.onDrop(of: ["public.data"], isTargeted:nil) { providers, location in                     for provider in providers { provider.loadDataRepresentation(forTypeIdentifier: "public.data") { (data, err) in                             if let safeData = data {                                 self.document.setBackgroundData(data: safeData)                             } else {                                 print("problem")                             }                         }                     } ]                    return self.drop(providers: providers, al: location)                 }             } The problem is if I define and on drop of public.adobe.pdf, nothing is recognized when I drag a file into it, and when I specify public.data and I want to extract the provider data for that identifier, I get this console message : " Cannot find representation conforming to type public.data". I'm trying to build a Mac app (Appkit). Thanks a lot.
