Question

I need to upload an mp4 video file from iPhone/iPad to a server, also in the background, so I read that is possible with URLSession.uploadTask(with: URLRequest, from

Answer 1

solution as of 2020 with native URLSession to run background upload with uploadTask and multipart/form-data:

• I followed this tutorial on setting up request for multipart/form-data as it required for my NodeJS server
• Then I change a bit on the part for setting up URLSession:

let config = URLSessionConfiguration.background(withIdentifier: "uniqueID")
let session = URLSession(configuration: config, delegate: self, delegateQueue: nil)

// This line is important: here we use withStreamedRequest
let task = session.uploadTask(withStreamedRequest: request)

task.resume()

A little bit about my server side:

• It's written in NodeJS with Express
• File uploading is handled by Multer: the way I did it is really standard, you can find in many tutorials online

Hope this help
