How do I change height of iOS custom keyboard?

Question

I've been working on an iOS custom keyboard (in an .xib file), but I haven't been able to change the height within storyboard. Is there a way to change the height of the keyboard within storyboard or do I have to find a way to do it programmatically?

Here's my solution as Apple Documentation Suggests :

You can adjust the height of your custom keyboard’s primary view using Auto Layout. By default, a custom keyboard is sized to match the system keyboard, according to screen size and device orientation. A custom keyboard’s width is always set by the system to equal the current screen width. To adjust a custom keyboard’s height, change its primary view's height constraint.

 override func viewWillAppear(animated: Bool) {
    let desiredHeight:CGFloat!
    if UIDevice.currentDevice().userInterfaceIdiom == .Phone{
            desiredHeight = 259
    }else{
        if UIDevice.currentDevice().orientation == .Portrait{
            desiredHeight = 260
        }else {
            desiredHeight = 300
        }
    }
    let heightConstraint = NSLayoutConstraint(item: view, attribute: NSLayoutAttribute.Height, relatedBy: NSLayoutRelation.Equal, toItem: nil, attribute: NSLayoutAttribute.NotAnAttribute, multiplier: 1.0, constant: desiredHeight)
    view.addConstraint(heightConstraint)

}

documentation said ,you can adjust your keyboard height after being layout ,so you can use viewWillAppear to do so.
