I have a workaround for adding UIRefreshControl, not an elegant way but it works fine for me.
First I find the MXScrollView and add UIRefreshControl to it. This refresh control will be placed under your parallax view, so I moved its Z position to top and move its frame to be on top of the view.

        segmentedPager.subviews.forEach { (view) in
            if let scrollView = view as?  UIScrollView {
                contentScrollView = scrollView
                contentScrollView?.addSubview(refreshControl)
                contentScrollView?.refreshControl = refreshControl
                contentScrollView?.scrollsToTop = false
                
                refreshControl.addTarget(self, action: #selector(refreshContent), for: .valueChanged)
                refreshControl.layer.zPosition = -1

                if let refreshView = refreshControl.subviews.first {
                    let frame = refreshView.frame
                    refreshView.frame = CGRect(x: frame.origin.x, y: -(parallax.bounds.height / 2), width: frame.size.width, height: frame.size.height)
                }

            }
        }

Now you will see your refresh control when pulling down, but the content inset will acting weird. In MXSegmentedPager.m you need to prevent MXScrollView from setting content inset in -(void)layoutContentView with this code.

- (void)layoutContentView {
    CGRect frame = self.bounds;
    
    frame.origin = CGPointZero;
    self.contentView.frame = frame;
    self.contentView.contentSize = self.contentView.frame.size;
    self.contentView.scrollEnabled = !!self.contentView.parallaxHeader.view;
    if (!self.contentView.refreshControl.isRefreshing) {
        self.contentView.contentInset = UIEdgeInsetsMake(self.contentView.parallaxHeader.height, 0, 0, 0);
    }
}
