Why is static TableView not responsive?

Question

Apple Xcode

There is a TableViewController with static table. When you click on one of the cells, you need to perform some action. In the properties of this cell, I allowed its selection. The cell is highlighted in color when clicked, but no action occurs (the didSelectRowAtIndexPath method does not respond). With delegate everything is all right.

Answer 1

We make ourselves a delegate of your gestur. In the method
Return true/false depending on whether the keyboard is on the screen.

Answer 2

Update! By trial and error, I figured out that the problem is in the method:

let tap: UITapGestureRecognizer = UITapGestureRecognizer(target: self, action: #selector(MainTableViewController.dismissKeyboard))
        view.addGestureRecognizer(tap)

Can it be replaced by another? It is very necessary that the keyboard disappear when you click in any area
