Discussion
In iOS 10 and earlier, this method returns the document picker view controller from the most recently used Document Provider extension. If no valid Document Provider can be found, it defaults back to iCloud Drive.
In iOS 11 and later, it returns the standard browser interface. This interface is the same one used by the UIDocument class.
