NSHttpCookieStorage.SharedStorage.Cookies Alway Empty
USUniversity ✭✭✭
Am I doing this right? I have this code is a simple Xamarin.Mac app.
var cookieStorage = NSHttpCookieStorage.SharedStorage;
var cookies2 = cookieStorage.Cookies;
cookies2 is always empty!
/Users//Library/Cookies has plenty of cookies, as does the Privacy section in the Safari Preferences.
Here's my environment.

Refer to the Apple doc:
https://developer.apple.com/documentation/foundation/nshttpcookiestorage
We will get that each app has its own cookie storage. We can't use this API to read all the cookies on the device which doesn't belong to the app itself.
And we can useNSHttpCookieStorage.GetSharedCookieStorage("groupContainerIdentifier");to access the cookies in the same group.
However, we need to group them first:

Thanks @LandLu, that makes sense. I will add a WebView to my test app and see what I get.
Waiting for your update.
@LandLu , it worked great. I added a WebView and after visiting some websites, I was able to see all kinds of cookies. Thanks again for your timely, and relevant answer. You guys are the best!
