If you need to do something based on your view's frame - override layoutSubviews and call layoutIfNeeded

    override func layoutSubviews() {
    super.layoutSubviews()

    yourView.layoutIfNeeded()
    setGradientForYourView()
}

I had the issue with viewDidLayoutSubviews returning the wrong frame for my view, for which I needed to add a gradient. And only layoutIfNeeded did the right thing :)
