IOS - When I rotate a UIView the edges become distorted

Question

Distorted UIView Screenshot

I tried rotating a UIView using:

view.transform = CGAffineTransform.init(rotationAngle: 45)

only to see the edges of the view looked very distorted. Is this normal? And if it is, are there any workarounds to straighten the edges?

EDIT

I found that adding the piece of code below works the best

view.layer.allowsEdgeAntialiasing = true

Still looked pretty distorted. I also ran this on my own ios device and got the same result. — Brandon Cornelio, Oct 13 '16 at 09:50

refer this link,

After that implement this for swift 3.0,

view.layer.borderWidth = 3
view.layer.borderColor = UIColor.clear.cgColor
view.layer.shouldRasterize = true
view.layer.rasterizationScale = UIScreen.main.scale()
