You can set attributed string to navigation bar title.

let navTitle = NSAttributedString(string: "My Title", attributes:
                [.underlineStyle: NSUnderlineStyle.styleSingle.rawValue])
self.title = navTitle.string

If navigationController is nil then you can't set title with above code.

Alternatively, you can use custom title view in navigation bar.

let titleView = UILabel() // set other table properties
let navTitle = NSAttributedString(string: "My Title", attributes:
                [.underlineStyle: NSUnderlineStyle.styleSingle.rawValue])
titleView.attributedText = navTitle

//set title view to navigation       
self.navigationItem.titleView = titleView

Your first block of code won't work since you don't actually use the attributed string. — rmaddy, Jun 13 '18 at 14:45
