Tell me how to add collection view. I will wait for you.

Thank you for replaying I would be happy to help me fatal error: unexpectedly found nil while unwrapping an Optional value func viewControllerWithColorAndTitle (_ color: UIColor, title: String) -> UIViewController...

I want to add collection view to vc1, vc2, vc3, vc4. let slidingContainerViewController = SlidingContainerViewController ( parent: self, contentViewControllers: [vc1, vc2, vc3, vc4], titles: ["First", "Second", "Third", "Forth"]) self.view.addSubview(slidingContainerViewController.view)
