Цвет текста в HUD

Вот мой код:

override func draw(_ rect: CGRect) {

        let boxWidth: CGFloat = 96
        let boxHeight: CGFloat = 96

        let boxRect = CGRect(x: round((bounds.size.width - boxWidth) / 2),
                             y: round((bounds.size.height - boxHeight) / 2),
                             width: boxWidth, height: boxHeight)

        let roundedRect = UIBezierPath(roundedRect: boxRect, cornerRadius: 10)
        UIColor(white: 0.3, alpha: 0.8).setFill()
        roundedRect.fill()

        if let image = UIImage(named: "Checkmark") {
            let imagePoint = CGPoint(
                x: center.x - round(image.size.width / 2),
                y: center.y - round(image.size.height / 2) - boxHeight / 8)
            image.draw(at: imagePoint)
        }

        let attribs = [ kCTFontAttributeName: UIFont.systemFont(ofSize: 66.0), kCTForegroundColorAttributeName: UIColor.white]
        let textSize = text.size(withAttributes: attribs as [NSAttributedString.Key : Any])
        let textPoint = CGPoint(
            x: center.x - round(textSize.width / 2),
            y: center.y - round(textSize.height / 2) + boxHeight / 4)
        text.draw(at: textPoint, withAttributes: attribs as [NSAttributedString.Key : Any])

    }

Цвет текста в HUD черный. Почему и как я могу изменить его на белый?
