For me, Paul's answer worked. But for custom fonts I had to put following hack.

//Please take care of force unwrapping
let data = htmlString.data(using: String.Encoding.unicode)! 
        let mattrStr = try! NSMutableAttributedString(
            data: data,
            options: [NSAttributedString.DocumentReadingOptionKey.documentType: NSAttributedString.DocumentType.html],
            documentAttributes: nil)
        let normalFont = UIFontMetrics.default.scaledFont(for: UIFont(name: "NormalFontName", size: 15.0)!)//
        let boldFont = UIFontMetrics.default.scaledFont(for: UIFont(name: "BoldFontName", size: 15.0)!)
        mattrStr.beginEditing()
        mattrStr.enumerateAttribute(.font, in: NSRange(location: 0, length: mattrStr.length), options: .longestEffectiveRangeNotRequired) { (value, range, _) in
            if let oFont = value as? UIFont{
                mattrStr.removeAttribute(.font, range: range)
                if oFont.fontName.contains("Bold"){
                    mattrStr.addAttribute(.font, value: boldFont, range: range)
                }
                else{
                    mattrStr.addAttribute(.font, value: normalFont, range: range)
                }

            }
        }
