From this answer https://stackoverflow.com/a/31652184/3249196 , if you want an all white background without the grey overlay justr replace tintColor and backgroundColor with UIColor.white

extension UISegmentedControl {
    func removeBorders() {
        setBackgroundImage(imageWithColor(color: backgroundColor!), for: .normal, barMetrics: .default)
        setBackgroundImage(imageWithColor(color: tintColor!), for: .selected, barMetrics: .default)
        setDividerImage(imageWithColor(color: UIColor.clear), forLeftSegmentState: .normal, rightSegmentState: .normal, barMetrics: .default)
    }

    // create a 1x1 image with this color
    private func imageWithColor(color: UIColor) -> UIImage {
        let rect = CGRect(x: 0.0, y: 0.0, width:  1.0, height: 1.0)
        UIGraphicsBeginImageContext(rect.size)
        let context = UIGraphicsGetCurrentContext()
        context!.setFillColor(color.cgColor);
        context!.fill(rect);
        let image = UIGraphicsGetImageFromCurrentImageContext();
        UIGraphicsEndImageContext();
        return image!
    }
}
