What is the purpose of opening this? The numberOfItems are asked by the dataSource, which is implemented by the client side. So the client side already knows better about the number.

Hi After pager.reloadData() I call: pager.scrollToItem(at: index, animated: true) (index I get from datasource) The app crash because the pager doesn't have the item at index

pager.reloadData() {
