This variation is based on @Luca's accepted answer, but allows you to optionally customize the point size of the font, should result in a centered image, and doesn't make the background color white.

extension String {
    func image(pointSize: CGFloat = UIFont.systemFontSize) -> UIImage? {
        let nsString = self as NSString
        let font = UIFont.systemFont(ofSize: pointSize)

        let size = nsString.size(withAttributes: [.font: font])
        UIGraphicsBeginImageContextWithOptions(size, false, 0)
        let rect = CGRect(origin: .zero, size: size)
        nsString.draw(in: rect, withAttributes: [.font: font])
        let image = UIGraphicsGetImageFromCurrentImageContext()
        UIGraphicsEndImageContext()
        return image
    }
}
