Clearing Cookies in Objective C ios 10

In my app users login through a SafariWebViewController and I am trying to implement a logout button for my app. When the button is pressed the following code is called.

    NSHTTPCookieStorage *storage = [NSHTTPCookieStorage 
    sharedHTTPCookieStorage];
        for (NSHTTPCookie *cookie in [storage cookies]) {
            [storage deleteCookie:cookie];
        }
        [[NSUserDefaults standardUserDefaults] synchronize];

The code does not properly clear the cookies and when the user tries to login the SafariWebViewController remembers their last login. I am not sure what I am doing wrong that the cookies are not clearing. Any help would be appreciated.

NSHTTPCookieStorage only affects UIWebView and your own app's requests, it doesn't have any effect on WKWebView or SFSafariViewController, they use their own cookie handler.

SFSafariViewController also shares cookies with the Safari app; my guess is only the user can clear the cache themselves (for obvious security/privacy reasons).

Use UIWebView or WKWebView if you want to control the cache.
