    self.pageviewcontroller.delegate = self

I've tested the following code and it works

This is my controller class:

class PageViewController: UIPageViewController, UIPageViewControllerDataSource, UIPageViewControllerDelegate {

In that class I've created this variable:

lazy var pageArra: [UIViewController] = {
       return[self.VCInstance("ONE"),self.VCInstance("TWO"),self.VCInstance("THREE"),self.VCInstance("FOUR")]
    }()

Which uses this function to get the storyboard assets. I gave 4 ViewControllers the ID's listed above

private func VCInstance(_ name: String) -> UIViewController {
        return UIStoryboard(name: "Main", bundle: nil).instantiateViewController(withIdentifier: name)
    }

This is my viewDidLoad:

override func viewDidLoad() {
    super.viewDidLoad()
    dataSource = self
    delegate = self
    var pageControl = UIPageControl()
    pageControl = UIPageControl.appearance()
    pageControl.pageIndicatorTintColor = .gray
    pageControl.currentPageIndicatorTintColor = UIColor(red: 0.00, green: 1.0, blue: 1.0, alpha: 1.0)
}

And This is how I get it to clear when it loads

override func viewDidLayoutSubviews() {
    super.viewDidLayoutSubviews()
    if view is UIScrollView {
            view.frame = UIScreen.main.bounds
        } else if view is UIPageControl {
            view.backgroundColor = .clear
        }
}

Plus all of the datasource and delegate required methods
