我正在尝试将渐变应用于主视图的顶部,左侧和右侧约束的视图,但由于某种原因,渐变不会覆盖应用于视图的整个宽度(请参阅黄色图片).

class ViewController: UIViewController {

    @IBOutlet weak var myView: UIView!

    override func viewDidLoad() {
        super.viewDidLoad()

        let gradient = CAGradientLayer()
        gradient.colors = [UIColor.blue.cgColor, UIColor.white.cgColor]
        gradient.startPoint = CGPoint(x:00, y:00)
        gradient.endPoint = CGPoint(x:0, y:0.6)
        gradient.frame = myView.bounds
        myView.clipsToBounds = true
        myView.layer.insertSublayer(gradient, at: 0)
    }
}

我究竟做错了什么？
