Updated @Luca Angeletti answer for Swift 3.0.1

extension String {

    func image() -> UIImage? {
        let size = CGSize(width: 30, height: 35)
        UIGraphicsBeginImageContextWithOptions(size, false, 0);
        UIColor.white.set()
        let rect = CGRect(origin: CGPoint(), size: size)
        UIRectFill(CGRect(origin: CGPoint(), size: size))
        (self as NSString).draw(in: rect, withAttributes: [NSFontAttributeName: UIFont.systemFont(ofSize: 30)])
        let image = UIGraphicsGetImageFromCurrentImageContext()
        UIGraphicsEndImageContext()
        return image
    }
