You mentioned in one of your comments that you want to change the constraints when the user presses a button. You can achieve this in less code by making an outlet to the constraint. Find the constraint in the document outline page and CTRL + Drag to your class to create an outlet to the constraint. Then you can change the constant in code easier.

@IBOutlet weak var topConstraint: NSLayoutConstraint!
@IBOutlet weak var bottomConstraint: NSLayoutConstraint!

func buttonPressed() {
    if (/* some condition */) {
        self.topConstraint.constant += 8
        self.bottomConstraint.constant += 8
    } else {
        // Return the constraints to normal, or whatever you want to do
    }
}
