If you create a cookie and add to the WKWebViewConfiguration the completionHandler returns 'Cookies synced' suggesting cookie was added with success. However, upon inspection of app in Safari the cookie is not there. This is broken in iOS 18 beta and works in previous versions without issue. Did Apple change the WKWebView API and break this feature? code snippet: NSDictionary* settings = self.commandDelegate.settings; WKWebViewConfiguration* configuration = [self createConfigurationFromSettings:settings]; configuration.userContentController = userContentController; NSMutableDictionary *cookieProperties = [NSMutableDictionary dictionary]; [cookieProperties setObject:@"foo" forKey:NSHTTPCookieName]; [cookieProperties setObject:@"bar" forKey:NSHTTPCookieValue]; [cookieProperties setObject:@"mydomain.com" forKey:NSHTTPCookieDomain]; [cookieProperties setObject:@"mydomain.com" forKey:NSHTTPCookieOriginURL]; [cookieProperties setObject:@"/" forKey:NSHTTPCookiePath]; NSHTTPCookie *cookie = [NSHTTPCookie cookieWithProperties:cookieProperties]; [configuration.websiteDataStore.httpCookieStore setCookie:cookie completionHandler:^{NSLog(@"Cookies synced");}]; WKWebView* wkWebView = [[WKWebView alloc] initWithFrame:self.engineWebView.frame configuration:configuration];

Unable to create a cookie using WebKit API or manually create a cookie in Safari with SameSite=None on a device using iPadOS 18 beta. In Safari, the None option is still in the drop down as a selection for SameSite which leads me to believe this is a bug. Is this going to be fixed in the release version of iOS 18?
