UIBlurEffect not working as expected on my UIView

I have a UIView and I set its frame in my viewDidLoad. I then use a blurBackgroundForView function to blur it:

override func viewDidLoad() {
  super.viewDidLoad()
  view.frame = CGRectMake(0, superView.frame.maxY-height, superView.frame.width, height)
  // The view is supposed to peak in from the bottom 
  AnimationHelper.blurBackgroundForView(view)
}

static func blurBackgroundForView(view: UIView!){
  view.backgroundColor = .clearColor()
  let blurEffect = UIBlurEffect(style: .Light)
  let blurEffectView = UIVisualEffectView(effect: blurEffect)
  blurEffectView.frame = view.frame
  view.insertSubview(blurEffectView, atIndex: 0)
  }
}

The issue is that the background of the UIView is NOT blurred. When I move the function call of blurBackgroundView(view) above the view.frame = ... I get a blurred view, but the blurred view is much to large.

The frame for blurEffectView should be CGRectMake(0, 0, superview.frame.width, height)
