Answer 1

After some attempts, I saw the URLSession.uploadTask(with: URLRequest, fromFile: URL) method attaches the file as raw body to the request, so the problem was the server counterpart that was parsing form-data requests instead raw body requests.After I fixed the server side script, the upload works in background with this code:

    var request = URLRequest(url: "my_url")
    request.httpMethod = "POST"
    request.setValue(file.lastPathComponent, forHTTPHeaderField: "filename")


    let sessionConfig = URLSessionConfiguration.background(withIdentifier: "it.example.upload")
    sessionConfig.isDiscretionary = false
    sessionConfig.networkServiceType = .video
    let session = URLSession(configuration: sessionConfig, delegate: self, delegateQueue: OperationQueue.main)

    let task = session.uploadTask(with: request, fromFile: file)
    task.resume()
