Here is for Swift 4 ++ also using a global instance for UIAlert

func showAlertError(withTitle title: String, withMessage message: String) {
    var dialogTitle = title
    if dialogTitle.isEmpty { dialogTitle = "Error:" }


    let attributedString = NSAttributedString(string: dialogTitle, attributes: [
        NSAttributedString.Key.font : UIFont.systemFont(ofSize: 15),
        NSAttributedString.Key.foregroundColor : UIColor.red
        ])

    let alert = UIAlertController(title: "", message: message, preferredStyle: .alert)
    alert.setValue(attributedString, forKey: "attributedTitle")
    let ok = UIAlertAction(title: "OK", style: .default, handler: nil)

    alert.addAction(ok)
    DispatchQueue.main.async(execute: {
        self.present(alert, animated: true)
    })
}
