openURL closure of DropboxClientsManager.authorizeFromController(_:controller:openURL:) not executed

I have this code:

    DropboxClientsManager.authorizeFromController(UIApplication.shared, controller: self) {

        (url: URL) in

        print("**!!!**")

        UIApplication.shared.open(url, options: [:]) {

            success in

            print("**!!!")

            self.navigationItem.prompt = "**!!!"

        }

        print("*****")

        self.navigationItem.prompt = "*****"

    }

I don't think the closure is running at all. It is the openURL argument. None of the print statements show. None of the changes to navigationItem.prompt show. When I comment the intire UIApplication.shared.open(url:options:completionHandler:) statement, there are no changes.

Does anyone know what the matter is?

Any help will be appreciated.

I think the last reply of this post answers the question: #M11267 .

Is it correct that if the Dropbox app is not installed then openURL is not called?

That code will only get run once the user returns to your app after authorizing it in the app authorization flow. Are you successfully completing the app authorization flow?

First, please make sure you've implemented all of the pieces as documented here:

https://github.com/dropbox/SwiftyDropbox#handling-the-authorization-flow

Note that whether the flow is handled by the browser or by the official Dropbox app, the flow works the same way; the user is redirected back to your app, and that code block should be run.
