Like for a UITableView, there is a function to reload the pager. Just call reloadPagerTabStripView() after you received your data from your server and initialized your UIViewController in func viewControllers(for pagerTabStripController: PagerTabStripViewController)

This is throwing "Fatal error: Index out of range" when calling reloadPagerTabStripView() function after updating the controllers. The file and line of crash is: ButtonBarPagerTabStripViewController.swift -> collectionView(_: UICollectionView, layout: UICollectionViewLayout, sizeForItemAtIndexPath: IndexPath) method's first statement: guard let cellWidthValue = cachedCellWidths?[indexPath.row]

Just create an EmptyChildViewController.swift:

import UIKit
import XLPagerTabStrip

class EmptyChildViewController: UIViewController, IndicatorInfoProvider {

    override func viewDidLoad() {
        super.viewDidLoad()
        // do nothing
    }
    
    func indicatorInfo(for pagerTabStripController: PagerTabStripViewController) -> IndicatorInfo {
        return IndicatorInfo(title: "")
    }
}

set empty child view when your data in not ready

override func viewControllers(for pagerTabStripController: PagerTabStripViewController) -> [UIViewController] {
        if data.count > 0 {
             // get datas

           return [childVC]
       } 

        let empty = EmptyChildViewController()
        
        return [empty]
    }

How can you make the dynamically created view controller instance conform to the IndicatorInfoProvider protocol?
