When you use UIPageViewController the dots should be visible by default. I guess you have a white background and the dots are also white, so you just don't see them.

Try to change dots color:

Swift 4/5:

var appearance = UIPageControl.appearance(whenContainedInInstancesOf: [UIPageViewController.self])
appearance.pageIndicatorTintColor = UIColor.red
appearance.currentPageIndicatorTintColor = UIColor.red

Swift 3:

var appearance = UIPageControl.appearanceWhenContainedIn(UIPageViewController.self, nil)
appearance.pageIndicatorTintColor = UIColor.red
appearance.currentPageIndicatorTintColor = UIColor.red

If it doesn't help, make sure that you are using UIPageViewControllerTransitionStyleScroll transition style.

Also, make sure to implement this methods from the UIPageViewControllerDataSource: presentationCount(for:) and presentationIndex(for:).
