I want to delete a tableview cell row when the button deleteButton is triggered. You can see exactly what I am looking for in the gif below. When the user taps the deleteButton is should call the func didDelete. Right now if you press the button nothing happens. And every time the delete button is called it should delete the cell which the button was in.
