Rounded Corners only on Top of a UIView

Solution
You can do this by setting a `mask` on your view's layer:
CAShapeLayer * maskLayer = [CAShapeLayer layer];
maskLayer.path = [UIBezierPath bezierPathWithRoundedRect: self.bounds byRoundingCorners: UIRectCornerTopLeft | UIRectCornerTopRight cornerRadii: (CGSize){10.0, 10.}].CGPath;
self.layer.mask = maskLayer;
IMPORTANT: You should do this in your view's `layoutSubviews()` method, so the view has already been resized from the storyboard
In Swift <= 1.2
let maskLayer = CAShapeLayer()
maskLayer.path = UIBezierPath(roundedRect: bounds, byRoundingCorners: .TopLeft | .TopRight, cornerRadii: CGSize(width: 10.0, height: 10.0)).CGPath
layer.mask = maskLayer
Swift 2.x
let maskLayer = CAShapeLayer()
maskLayer.path = UIBezierPath(roundedRect: bounds, byRoundingCorners: UIRectCorner.TopLeft.union(.TopRight), cornerRadii: CGSizeMake(10, 10)).CGPath
layer.mask = maskLayer
Swift 3.x
let maskLayer = CAShapeLayer()
maskLayer.path = UIBezierPath(roundedRect: view.bounds, byRoundingCorners: [.topLeft, .topRight], cornerRadii: CGSize(width: 10, height: 10)).cgPath
layer.mask = maskLayer
Problem
Hi i am searching a clean solution without overwriting `drawRect` or stuff like that to create a `UIView` with Rounded corners on the Top of the View. My main problem here is to create variable solution if the view is getting resized or something like that. Is there a clean solution? Apple is this doing too on the first table item. it can't be so hard to do this.
