Answer 1

Check List
tableview delegate is set properly
tableview selection mode == No Selection, then change to single selection
function name is correct func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
are you using any tap gesture on this view? remove it.

If you are editing UITextView will can't call to `didselectRowAt. Try to get the Your MentionUserCell, IndexPath in UITextView's methods and handle there. Example:
func textViewDidChange(_ textView: UITextView) {
var parentView = textView as UIView
while !(parentView is UITableViewCell) {
parentView = parentView.superview!
}
if let cell: MentionUserCell = parentView as? MentionUserCell {
if let indexPath = self.tableView.indexPath(for: cell) {
let yourIndexPath = indexPath
}
}
//your code
}
Hope it will help you.

When are using two or more cells the didSelectRow method is not working Well. You can use a button in cell.
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: "cellIdentifierName", for: indexPath) as! MentionUserCell
cell.username!.text = autoComplete[indexPath.row]
let button = cell.viewWithTag(101) as! UIButton
button.cellclick.addTarget(self, action: #selector(functionName(sender:)), for: .touchDown)
return cell
}
Now you get the indexPath:-
func functionName(sender:UIButton) {
let buttonPosition:CGPoint = sender.convert(CGPoint.zero, to:self.tableview)
let indexPath = self.tableview.indexPathForRow(at: buttonPosition)
print(indexPath.row)
}
