UIPageViewController with different ViewControllers, right way?

Question

Basically, I have a Table View Controller and a normal View Controller, I want to make it so that I can swipe between the view controllers like on the home screen of app (ob

This is an old question but since I bumped into this problem I'll post my solution.

The first time I did this I added my code

func pageViewController(pageViewController: UIPageViewController, didFinishAnimating finished: Bool, previousViewControllers: [UIViewController], transitionCompleted completed: Bool) { }

Which received problems when you continuously scroll the views using two fingers and didFinishAnimating is not called unless scrolling stops.

So I just used this delegate method instead.

func pageViewController(pageViewController: UIPageViewController, willTransitionToViewControllers pendingViewControllers: [UIViewController]) {

    let currentView = pendingViewControllers[0]

    if currentView is UINavigationController && currentView.restorationIdentifier == "Settings" {
        index = 0
    } else if currentView is UINavigationController && currentView.restorationIdentifier == "Main" {
        index  = 1
    } else if currentView is UINavigationController && currentView.restorationIdentifier == "Message" {
        index = 2
    }
}

Where currentView is the currentUIViewController (or UINavigationController like what I am using, using a restorationIdentifier to identify my navigation controller as well), and index is a global value to know which UIViewController in the array to instantiate.
