Redirect after login not completing and app is closing. (SwiftyDropBox)

Thanks for the additional information. In your original post though, you said "the app just quits with out throwing any errors after the redirect back to the app", however in your last reply you said it "still fails to redirect". Can you clarify what redirect does or doesn't occur, and when the app quits exactly?

In any case, if you can provide a sample project, that would be most helpful so we can reproduce it and look into it. Thanks in advance!
