How to fix: func selectRow in the TableView does not work when I click Cancel in search bar

Question

I have a TableView with a playlist of music tracks. When I click on the row, the track starts to play and the current row is selected. Also, I have a search bar, which works fine. But if I click on the row, then on the search bar and then I finally on the Cancel button - the row with the current track is not selected. In other situations, like forward or backward playback, the selection of rows works well. Simplified, my code looks like this:

class TableView: UIViewController, UISearchResaultUpdating, UISearchBarDelegate {
   ...
   private var currentSelectedRowIndex = 0
   func ...didSelectRowAt indexPath... {
      ...
      currentSelectedRowIndex = indexPath.row
      print(currentSelectedRowIndex)
   }

   ...
   func searchCancelButtonClicked... {
      print("Cancel button pressed")
      print(currentSelectedRowIndex)
      tableView.selectRow(at: IndexPath(row: currentSelectedRowIndex, section 0), animated: true, scrollPosition: .middle)
   }
}

//For example, I pressed second row

Console message:

1
Cancel button pressed
1

But the row is not selected, what's the problem?

If you look at the UITableView documentation , it clearly says that calling selectRow does not cause the delegate to receive tableView(_:didSelectRowAt:) .

You can move whatever you are doing in tableView(_:didSelectRowAt:) to another function and call that function in tableView(_:didSelectRowAt:) and searchCancelButtonClicked .

Or you can use the following code to manually invoke tableView(_:didSelectRowAt:) in searchCancelButtonClicked .

func searchCancelButtonClicked() {
    print("Cancel button pressed")
    print(currentSelectedRowIndex)
    let indexPath = IndexPath(row: currentSelectedRowIndex, section: 0)
    
    yourTableViewOutlet.delegate?.tableView?(yourTableViewOutlet, didSelectRowAt: indexPath)
    tableView.selectRow(at: indexPath, animated: true, scrollPosition: .middle)
}
