Cell is not selectable embed UItableView inside main View?

Cell is not selectable embed UItableView inside main View?

I have UITableView embed inside a main UIView. My problem is when I click on a cell to select items, it is not responding to the selection or triggering the segue.

Note: In attributes inspecter
is selection supposed to be set to single selection?

Update Note: the prepareForSegue function is not triggering or print “test”.
