Unable to make some part of UILabel underline in Swift?

Question

I have a UILabel I want to make some part of it as underline. I am using below code for that. But it underline the whole label not the some part of label. Please tell me how can I make some part of label as Underline.

let attributedString = NSMutableAttributedString(string: "UserAgreement".localized)
attributedString.addAttribute(NSUnderlineStyleAttributeName, value: NSUnderlineStyle.styleSingle.rawValue, range: NSRange(location: 0, length: 10))

labelTc.attributedText = attributedString

I don't want to do with the storyboard

Try this

Swift 4

    let wholeStr = "Don't have an account? Register"
    //let rangeToUnderLine = (wholeStr as NSString).range(of: "Register")
    let rangeToUnderLine = NSRange(location: 0, length: 10))
    let underLineTxt = NSMutableAttributedString(string: wholeStr, attributes: [NSAttributedStringKey.font:UIFont.systemFont(ofSize: 20),NSAttributedStringKey.foregroundColor: UIColor.white.withAlphaComponent(0.8)])
    underLineTxt.addAttribute(NSAttributedStringKey.underlineStyle, value: NSUnderlineStyle.styleSingle.rawValue, range: rangeToUnderLine)
    labelTc.attributedText = underLineTxt

Swift 3.2

    let wholeStr = "Don't have an account? Register"
    //let rangeToUnderLine = (wholeStr as NSString).range(of: "Register")
    let rangeToUnderLine = NSRange(location: 0, length: 10))
    let underLineTxt = NSMutableAttributedString(string: wholeStr, attributes: [NSFontAttributeName:UIFont.systemFont(ofSize: 20),NSForegroundColorAttributeName: UIColor.white])
    underLineTxt.addAttribute(NSUnderlineStyleAttributeName, value: NSUnderlineStyle.styleSingle.rawValue, range: rangeToUnderLine)
    labelTc.attributedText = underLineTxt
