    Hi,

    I think you're right but not sure what I was doing wrong, the call is in my viewcontroller, however I tried

    DropboxClientsManager.authorizeFromController(UIApplication.shared, controller: UIApplication.shared.keyWindow!.rootViewController!, openURL: { (url: URL) -> Void in UIApplication.shared.open(url, options: [:], completionHandler: nil) })

    i.e. using rootViewController instead of self and it worked.

    Thanks for your response

    When/where are you calling authorizeFromController?

    This error message generally indicates that the authorization window can't be displayed because it relies on yourViewController, but theViewController wasn't in the window hierarchy (yet?) at time of the call. Perhaps your ViewController wasn't presented (or was already dimissed) at the time?
