How handle the UIPageViewController VCs rotating by viewWillTransitionToSize func?

I try to create UIPageVC with 3 pages. All is good, but when I rotate device and after this change page I will see that rotates only page, which is settled in PageVC in rotate moment.

How rotate other 2 VCs, when I rotate any page?

Maybe I can do this in PageVC class?

I used Swift 4.0, so I must use viewWillTransitionToSize func.

Thanks for all answers!

You could try overriding the viewWillTransitionToSize function and forward the message to all of your view controllers contained in your UIPageViewController.

fileprivate var yourViewControllers = [UIViewController]()    

override func viewWillTransition(to size: CGSize, with coordinator: UIViewControllerTransitionCoordinator) {
    super.viewWillTransition(to: size, with: coordinator)

    yourViewControllers.forEach({ $0.viewWillTransition(to: size, with: coordinator) })
}
