PageControl disappears on adding or removing new pages

[nor0x]

Thanks for sharing the control. I ran into an issue when using it in combination with UIPageViewController. When I update the number of UIViewControllers which are contained in the UIPageViewController the PageControl disappears.

I recorded this gif (https://abload.de/img/nov-03-201618-31-58a9jcm.gif) to demonstrate the issue. At first there are two UIViewController, which can be swipped through. With a click on the "+" button a new UIViewController gets added to the datasource of UIPageViewController - this makes the PageControl disappear.

For updating numberOfPages I wrote the following function

func mainPageViewController(mainPageViewController: MainPageViewController, didUpdatePageCount count: Int) { pageControl.numberOfPages = count }

Do you have an idea why this happens? THX
