I'm researching how to do a Sfarai Extension or Safari App Extension for a proudct that is current a Chrome extension using the chrome.cookies api for cookies. Is there a way to implement the getting & setting of 3rd party cookies in Native Safari App extension? I know that there is an NSHttpCookieStorage class that is for storing the cookies, but I want to be sure the cookies I set are used by the Safari browser on OSX High Sierra.
Can a native Safari App extension get & set 3rd party cookies?
