instead of creating ibaction in uitableviewcell class, addtarget button in viewcontroller class in cellforrow method:-
cell.radiobutton.addtarget(self, action: #selector(yourviewcontroller.somemethod(_sender:)), for: uicontrolevents.touchupinside) and call api in viewcontroller itself, wont have pass data:-
func somemethod(_sender: uibutton) { // call api here in view controller class }
