Answer 1

You can use:

For next page

pageViewController.setViewControllers(startingViewControllers,
                                                direction: UIPageViewControllerNavigationDirection.Forward,
                                                animated: true,
                                                completion: nil)

For previous page

pageViewController.setViewControllers(startingViewControllers,
                                                direction: UIPageViewControllerNavigationDirection.Reverse,
                                                animated: true,
                                                completion: nil)
