If you are using storyboard use this -


if let navigationObject = UIStoryboard(name: "storyboard_name", bundle: nil).instantiateViewController(withIdentifier: "viewcontroller_storyboardId") as? viewController_name {

navigationController?.pushViewController(navigationObject, animated: true)
}



You should add this first

There could be come following reasons



Check if name contains entertainment Or Entertainment as string
value? means case sensitivity(as a test do following and check)
data[indexPath.row].name.lowerCased() == "Entertainment".lowerCased()



Missing navigationController (navigation controller not embedded) if missing embed
navigationController to your root controller.



try removing dismiss(animated: true, completion: nil)


dismiss(animated: true, completion: nil)

I can go on until the moment that I select my result set like in the image below: exporting data set But once I go further in the process, in the last step I get: no query Note that in "source" it was suppose to show the query that originated the result set, but instead it says just "select.
