Unfortunately this is not possible on iOS. There are no APIs to have this kind of control over cookies in the `WKWebView.

We discussed this a little while ago and nothing has changed since then.

@farhanpatel Do you think this https://developer.apple.com/documentation/foundation/httpcookie/acceptpolicy can be used? Does that setting apply to WKWebView too?
