SFSafariViewController Remove OAuth2 Cookie

Question

I have an iOS application that authenticates with Uber API using OAuth2 in a UIWebView. When upgrading to iOS 9, I run in to the issue of ATS blocking the http

So I ran into this same issue and saw your question when searching for how to solve this. In my case the best solution I came up with was doing the logout stuff for in the app and then presenting a SFSafariViewController pointed at our logout url. I then used this to close the SFSafariViewController as soon as it was done loading:

extension AlertsTableViewController: SFSafariViewControllerDelegate {

    public func safariViewController(_ controller: SFSafariViewController, didCompleteInitialLoad didLoadSuccessfully: Bool) {
        if controller == logoutSVC {
            controller.dismiss(animated: false)
        }
    }

}

I stored the SFSafariViewController in logoutSVC so I only run this code if this is the logout SFSafariViewController. In your case it sounds like you just did an API call to revoke the OAuth token which is a little nicer since it doesn't show to the user at all but this is good for instances where you don't have such access. One more thing, for some reason I had to call the dismiss(animated: false) method on the SFSafariViewController instead of actual current UIViewController for some reason. Took me a sec to figure out why it wasn't working for me.
