I\'m in the progress of migrating my app from UIWebView to WKWebView. All is going well and working as I tinker more with it. However, I notice now that I can\'t download forum

Swift 4:

ChrisOSX's sollution also solved my issue. I'm trying to download a document from a link on a site after logging to that site. I've used WKZombie to scrape the link, and then I wanted to download the file using Alamofire. I added this

if let httpResponse = navigationResponse.response as? HTTPURLResponse, let url = httpResponse.url {
    let allHeaders = httpResponse.allHeaderFields.reduce([String : String](), { (result, next) -> [String : String] in
    guard let stringKey = next.key as? String, let stringValue = next.value as? String else { return result }
        var buffer = result
        buffer[stringKey] = stringValue
        return buffer
    })
    let cookies = HTTPCookie.cookies(withResponseHeaderFields: allHeaders, for: url)
    for cookie in cookies {
        HTTPCookieStorage.shared.setCookie(cookie)
    }
}

to:

func webView(_ webView: WKWebView, decidePolicyFor navigationResponse: WKNavigationResponse, decisionHandler: @escaping (WKNavigationResponsePolicy) -> Void)

After this, the cookies are stored in the shared cookies, and I was able to download the file with Alamofire without and changes to the download methods..
