When you add yourView to view then yourView will be front of your view. For example you have two view firstView and secondView you have to put like below if you want to add what you want.

view.addSubview(self.firstView)
view.addSubview(self.secondView)

then you have to give constraint like below :

self.secondView.translatesAutoresizingMaskIntoConstraints = false
 self.secondView.leftAnchor.constraint(equalTo: view.leftAnchor).isActive = true
 self.secondView.rightAnchor.constraint(equalTo: view.leftAnchor).isActive = true
 self.secondView.bottomAnchor.constraint(equalTo: view.bottomAnchor).isActive = true
 self.secondView.topAnchor.constraint(equalTo: self.firstView.bottomAnchor ).isActive = true
