Usage Example

import UIKit
import PageControl

class ViewController: UIViewController, UIScrollViewDelegate {
    
    @IBOutlet weak var scrollView: UIScrollView!
    @IBOutlet weak var pageControl: PageControl!

    override func viewDidLoad() {
        super.viewDidLoad()
        scrollView.delegate = self
        pageControl.numberOfPages = Int(scrollView.contentSize.width / scrollView.bounds.width)
        pageControl.addTarget(self, action: #selector(pageControlDidChangeCurrentPage(_:)), for: .valueChanged)
    }

    @objc func pageControlDidChangeCurrentPage(_ pageControl: PageControl) {
        scrollView.setContentOffset(CGPoint(x: scrollView.bounds.width * CGFloat(pageControl.currentPage), y: 0), animated: true)
    }

    func scrollViewDidScroll(_ scrollView: UIScrollView) {
        if scrollView.isDragging || scrollView.isDecelerating {
            let page = scrollView.contentOffset.x / scrollView.bounds.width
            pageControl.setCurrentPage(page)
        }
    }
