WKWebView Configuration Cookies not working
Cookies in WKWebView are broken. When manually setting a Cookie using the Configuration, it will be ignored by the web view.
Workaround: add a
UserScript with the following code:
document.cookies = 'cookie_optin=essential:1|analytics:0'
That’s a great way to automatically reject Cookies and especially to disable tracking to either propagate the user’s ATT decision or to avoid implementing ATT in the beginning.
