I'm downloading files using a dataTaskPublisher - and the actual download is going great. What I'm wondering is if there is any way to show the "percent downloaded"?

Here's my code:

Code Block swiftcancellable = URLSession.shared.dataTaskPublisher(for: url)
    .map { UIImage(data: $0.data) }
    .replaceError(with: nil)
    .handleEvents(receiveSubscription: { [weak self] _ in self?.onStart() },
                  receiveOutput: { [weak self] in self?.cache($0, id) },
                  receiveCompletion: { [weak self] _ in self?.onFinish() },
                  receiveCancel: { [weak self] in self?.onFinish() })
    .subscribe(on: Self.imageProcessingQueue)
    .receive(on: DispatchQueue.main)
    .sink { [weak self] in
            self?.image = $0
    }
