Original GitHub issue: https://github.com/OAuthSwift/OAuthSwift/issues/170

When I try to do oauthswift.authorize_url_handler = SafariURLHandler(viewController: self), I get the following error:

Attempt to present <SFSafariViewController: 0x7f9bb978feb0> on <My_App.ViewController: 0x7f9bb96424a0> whose view is not in the window hierarchy!

I've gotten SafariURLHandler to work using OAuth1Swift, but for some reason it returns this error with OAuth2Swift.
I looked into the source and saw nothing that would differentiate these classes enough to cause the issue.

For what it's worth, I'm trying to authenticate with Fitbit using the code -> token change per #159. I'm kinda stumped at this point...
