Underline button text in Swift

Question

I have UIButton. In interface builder I set its title to be \'Attributed\'. How can I make its title to be underlined from code in Swift?

@IBOutlet weak var myBt

• Swift 5.2.4
• Xcode 11.5

let attributes: [NSAttributedString.Key : Any] = [
NSAttributedString.Key.underlineStyle: 1,
NSAttributedString.Key.font: UIFont.systemFont(ofSize: 13),
NSAttributedString.Key.foregroundColor: UIColor.systemGray3
]

let attributedString = NSMutableAttributedString(string: "Text here", attributes: attributes)
button.setAttributedTitle(NSAttributedString(attributedString: attributedString), for: .normal)
