Subview is not resizing with the size changes of superView

Question

I have a superView and I created a new View to use as a subview in my code.

Notify Status View is the superView and Driver InfoView is subView:

But when I make changes to the size of NotifyStatusView, they changes work with every item in superView except Driver Info View: 2 different sizes of the superView:

The only thing I can think of is that I added the Driver View as a new View and drag and dropped it in to the SuperView.

Just adding the comment as the answer:

you need to call layoutIfNeeded() to tell your view to update the layout changes.

self.view.layoutIfNeeded()
