Can the height of the UISearchbar TextField be modified?

Question

I\'m testing out my UI and I find the search bar a little bit too narrow for my liking. I also want to make sure people with poorer vision or poorer manual dexterity have n

Based on thelearner's answer here's the code for Swift 5.* :

extension UISearchBar {
    func updateHeight(height: CGFloat, radius: CGFloat = 8.0) {
        let image: UIImage? = UIImage.imageWithColor(color: UIColor.clear, size: CGSize(width: 1, height: height))
        setSearchFieldBackgroundImage(image, for: .normal)
        for subview in self.subviews {
            for subSubViews in subview.subviews {
                if #available(iOS 13.0, *) {
                    for child in subSubViews.subviews {
                        if let textField = child as? UISearchTextField {
                            textField.layer.cornerRadius = radius
                            textField.clipsToBounds = true
                        }
                    }
                    continue
                }
                if let textField = subSubViews as? UITextField {
                    textField.layer.cornerRadius = radius
                    textField.clipsToBounds = true
                }
            }
        }
    }
}

private extension UIImage {
    static func imageWithColor(color: UIColor, size: CGSize) -> UIImage? {
        let rect = CGRect(x: 0, y: 0, width: size.width, height: size.height)
        UIGraphicsBeginImageContextWithOptions(size, false, 0)
        color.setFill()
        UIRectFill(rect)
        guard let image: UIImage = UIGraphicsGetImageFromCurrentImageContext() else {
            return nil
        }
        UIGraphicsEndImageContext()
        return image
    }
}

and here's how we can apply it:

searchBar?.setSearchTextField(height: 48)

and here's the result:
