Setting NSUnderlineStyle causes unrecogognized selector exception

Swift 5 version of Vlad Khambir answer,

let attributes = [NSAttributedString.Key.underlineStyle: NSUnderlineStyle.single.rawValue]

Change line:

let attributes = [NSUnderlineStyleAttributeName:NSUnderlineStyle.styleSingle]

to:

let attributes = [NSUnderlineStyleAttributeName:NSUnderlineStyle.styleSingle.rawValue]
