WKWebView and cookies

I am starting a request in a WKWebView on the iOS 9.3 simulator
let url = NSURL(string:"http://localhost:8000/";)
let req = NSMutableURLRequest(URL:url!)
webView.loadRequest(req)
and intercept the response where I try to print out the cookies
func webView(webView: WKWebView, decidePolicyForNavigationResponse
navigationResponse: WKNavigationResponse, decisionHandler:
(WKNavigationResponsePolicy) -> Void) {
if let httpResponse = navigationResponse.response as?
NSHTTPURLResponse {
if let headers = httpResponse.allHeaderFields as? [String:
String], url = httpResponse.URL {
NSLog("cookies for %@", url)
let cookies =
NSHTTPCookie.cookiesWithResponseHeaderFields(headers, forURL: url)
for cookie in cookies {
NSLog(cookie.description)
NSLog("found cookie " + cookie.name + " " +
cookie.value)
}
NSLog("cookies for %@ done", url)
}
}
decisionHandler(WKNavigationResponsePolicy.Allow)
}
The first request is to show a form - no cookies
GET /
cookies for http://localhost:8000/
cookies for http://localhost:8000/ done
The POST then triggers the backend to set one
POST /
Set-Cookie: remember=1; Max-Age=300; Path=/; Expires=Tue, 12 Apr 2016
08:56:41 GMT
cookies for http://localhost:8000/
cookies for http://localhost:8000/ done
but I still cannot see the cookie on the client.
If I now restart the app the cookie is sent
GET /
Cookie: remember=1
and the backend confirms that the cookie is set - but I still can't see it
from the WKWebView.
cookies for http://localhost:8000/
cookies for http://localhost:8000/ done
I also tried to find it in the cookie storage
NSHTTPCookieStorage.sharedHTTPCookieStorage().cookies!
but that does not seem to have it either.
After lots of reading of StackOverflow and searching the mailing list
archives I am left a bit puzzled.
What am I missing here?
cheers,
Torsten
