Handle popups/tabs in SFSafariViewController

Is there any way to handle links that open popup windows/new tabs in SFSafariViewController?

I'm implementing a SoundCloud login flow in my app. The app opens

https://soundcloud.com/connect

in an

SFSafariViewController

with a

redirect_uri

that uses my app's custom URL scheme to receive the response. It works fine for direct SoundCloud logins, but fails when trying to use their "Sign in with Google" button.

In Safari, that button opens a new tab (popup on desktop) with a Google sign-in page, which then communicates back to the SoundCloud tab via

postMessage

. This login flow works fine if you use the mobile Safari app, but fails in an

SFSafariViewController

(clicking the button goes to a white page with a Google url:

https://accounts.google.com/o/oauth2/auth?...

).

Right now my workaround is to advise users using Google to tap the Safari icon on the

SFSafariViewController

to complete the login flow in the Safari app, but I'm wondering if there's a way to handle this without leaving my app.
