Please Try this,

    func scrollViewDidEndDecelerating(_ scrollView: UIScrollView) {
        let row = scrollView.contentOffset.x / cellWidth
        currentIndexShown = Int(row)

    }

  func scrollViewDidScroll(_ scrollView: UIScrollView) {

        if scrollView.contentOffset.x < cellWidth * CGFloat(currentIndexShown){
            scrollView.contentOffset =  CGPoint(x: cellWidth * CGFloat(currentIndexShown), y: -20)
            scrollView.bounces = false
        } else {
            scrollView.bounces = true
        }
}
