            self.currentIndex = 0
        })
    } else {
        **/* here unexpectedly found nil while unwrapping the value. */** self.pageController.setViewControllers([self.contentViewController(atIndex: self.currentIndex+1)], direction: UIPageViewControllerNavigationDirection.forward, animated: true, completion: { (complete) -> Void in

I'm bit confused. What is the reason of using a PageController if you are using LIHImageSlider?

I am having exact same issue, please have look on this, It only occurs when I am on other view controller and suddenly this error comes up.

U can define pageController as optional in this file:
public var pageController: UIPageViewController?
Accordingly error will get removed and crash won't occur then.
