Unable to reload the data at runtime.
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
Can you please send a demo project with issue. So I can resolve quickly.

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
