iOS custom keyboard changing constraints

I am trying to create a custom keyboard in swift programmatically and have so far been able to create the constraints I want for portrait and landscape on iPhone, but only when I start the keyboard in the respective orientation.

The problem comes when I flip the device myself: Portrait, Landscape. I have stored my constraints in two arrays and am running this block of code in my viewDidLoad and viewWillTransition functions:

if UIScreen.main.bounds.height >= 568 {
        NSLayoutConstraint.deactivate(constraintsLandscape)
        NSLayoutConstraint.activate(constraintsPortrait)
}
else if UIScreen.main.bounds.height <= 414 {
        NSLayoutConstraint.deactivate(constraintsPortrait)
        NSLayoutConstraint.activate(constraintsLandscape)
}

Any help with this is appreciated.

Current portrait and landscape

if this is inside a method, do u call it after the screen rotates ? if dont you can check device rotation overriding this method: 

override func viewWillTransition(to size: CGSize, with coordinator: UIViewControllerTransitionCoordinator) {
    super.viewWillTransition(to: size, with: coordinator)
    if UIDevice.current.orientation.isLandscape {
        print("Device is in Landscape mode")
        NSLayoutConstraint.deactivate(constraintsPortrait)
        NSLayoutConstraint.activate(constraintsLandscape)
    } else {
        print("Device is in Portrait mode")
        NSLayoutConstraint.deactivate(constraintsLandscape)
        NSLayoutConstraint.activate(constraintsPortrait)
    }
}

if you are already doing this, then you just need to call self.view.layoutifNeeded() after making changes to your constraints.
