Swift 3.0

Based on Sachin answer - bit more generic - just add next element to views array

var views = [ViewController(), ViewController2(), ViewController3(), ViewController4()]

func setupScrollView() {
    scrollView.frame = views.first!.view.frame
    scrollView.contentSize = CGSize(width: CGFloat(views.count) * width, height: 0)
    _ = views.map({ addViewToScrollView($0) })
    _ = views.map({ $0.view.frame.origin =  CGPoint(x: CGFloat(views.index(of: $0)!) * width, y: 0) })
}

func addViewToScrollView(_ viewController: UIViewController) {
    scrollView.addSubview(viewController.view)
    views.willMove(toParentViewController: self)
    addChildViewController(viewController)
}
