contentViewController won't scroll to specific page programmatically

[helloC1ndy]

Hi, thank you for sharing this great project with everyone! I really like it! But I have a little issue here hoping someone could help me. Thanks a lot!!

About The Issue

I want to add my pages dynamically, reload both menu & content, and then scroll the menu & content to the last page. It turns out menuViewController works successfully, but contentViewController just can't scroll to the last page. Not sure why.

My Tries & Results

1. reload first, scroll later

func addNewPage() {
        let vc = self.storyboard!.instantiateViewController(withIdentifier: "myViewController")
        pageList.append(vc)

        let lastPageIndex = pageList.endIndex
        
        menuViewController.reloadData()
        contentViewController.reloadData()

        menuViewController.scroll(index: lastPageIndex)
        contentViewController.scroll(to: lastPageIndex, animated: true)
    }

Result: menuViewController will scroll to the last index, but contentViewController always stays at first index.

2. use reload-with-preferredFocusIndex function

func addNewPage() {
        let vc = self.storyboard!.instantiateViewController(withIdentifier: "myViewController")
        pageList.append(vc)

        let lastPageIndex = pageList.endIndex
        
        menuViewController.reloadData(with: lastPageIndex, completionHandler: nil)
        contentViewController.reloadData(with: lastPageIndex, completion: nil)
        
    }

Result: menuViewController will scroll to the last index, so does contentViewController. BUT, contentViewController is totally blank!! (It didn't load its input views. But when I do a little scroll, like try to scroll to previous page a little but not really scroll to there, then contentViewController will load its input view successfully.)
