How to reload the data with updated data at runtime?

I am trying to reload the data after the tap on didselectRowAtIndexPath method
table reload fine but when I am scrolling the table than crash occurs in
below method

public func cellIdentifierUsingTableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> Node{
return arrayVisibles[indexPath.row]
}

Can you please send the solution to the problem, I am stuck in solving the problem

I have sent the whole class and In didSelectRowAtIndexPath I need nod so I have use the same in above without expending/collapsing the cell

[sazidIqabal]

Hi, Have any solution for that
