Below are how my views are organized in IB, top->bottom when the app is started.
The user can do something to make \"Category Table View Header\" temporarily expand
If you want to bring a subview to the front, you can use:
SWIFT 4 UPDATE
self.view.bringSubviewToFront(yourView)
SWIFT 3 UPDATE
self.view.bringSubview(toFront: yourView)
Send view to back:-
self.view.sendSubviewToBack(yourView)
self.view.sendSubview(toBack: yourView)
