The ImageDownloder has a delegate and you can use that to receive events.

// YourViewController
let downloader = KingfisherManager.shared.downloader  // Or another downloader if you are not using the default one.
downloader.delegate = self

extension YourViewController: ImageDownloaderDelegate {
    func imageDownloader(_ downloader: ImageDownloader, didReceive response: URLResponse, completionHandler: @escaping (URLSession.ResponseDisposition) -> Void) {
        // Do anything with response

        // Remember to call the handler with either `.allow` or `.cancel`.
        completionHandler(.allow)
    }
}
