How to animate the width and height of a UIView in Xcode?

Question

I have this subview I want to add to my main view, but make it expand from the origin. I read some of the Apple documentation but I don\'t understand where I am making mistake.

Answer 1

Swift 4

  UIView.animate(withDuration: 0.3, animations: {
        self.whiteBackgroundView.transform = CGAffineTransform(scaleX: 0.1, y: 0.1)
        self.view.layoutIfNeeded()
    }) { (finished) in
        // end of animation
    }
