You can call nextController.loadViewIfNeeded() and prevController.loadViewIfNeeded(), after showing visible controller!

pageViewController?.setViewControllers([controller], direction: direction, animated: animated, completion: { (_) in
    if let nextController = /*Find it*/ {
       nextController.loadViewIfNeeded()
    }
    if let prevController = /*Find it*/ {
       prevController.loadViewIfNeeded()
    }
})

You must find nextController and prevController in the code, I think that is easy.

You can use UIPageViewControllerDelegate to monitor the events of UIPageViewController, when it didFinishAnimating you can load the previous and next view.
