Programmatically expire SFSafariViewController session cookies

Is there a way to force SFSafariViewController to expire any session cookies that may have been set since the last app launch?


The use case for this is using SFSafariViewController for an oauth login page. If the user logs in via the oauth page, then logs out inside of the native part of the app, then attempts to log in again, they may be logged in automatically or session cookies from the previous user may be present. It would be ideal to have some API to call to signal to Safari Services that the current "session" has ended, and any session cookies should be discarded.


If the app is quit at any time, either by force-quitting or being ended by the system, this issue doesn't happen.
