When swiping not updating the page contol indexes

[saikishoreagrapalem]

When I swiping the view controllers the view controllers has changed but page control indexes are not updating and if I reached final page of the view controller its repeating again for first view controller ?

You need to rename func pageViewController(pageViewController: UIPageViewController, didFinishAnimating finished: Bool, previousViewControllers: [UIViewController], transitionCompleted completed: Bool)

to func pageViewController(_ pageViewController: UIPageViewController, didFinishAnimating finished: Bool, previousViewControllers: [UIViewController], transitionCompleted completed: Bool) Underscore makes the difference.
