Hi i have a problem when im parsing a Html to NSAtributtedString in a UILabel. The problem is in the strong text, the result is too bold (I guess when parsing the font is changed to "GibsonBold" and I need GibsonSemibold, or even change from Regular to Medium. I tried change tag to < b > or implement an style, but the result is always the same. Also I tried several extensions but I came out whit the same result.

This is the html String:

"<p>First text <strong> this text should be at lest Semibold</strong>. Final text.</p>"

Im using this two extension to parsing:

extension UIColor {
    var hexString:String? {
        if let components = self.cgColor.components {
            let r = components[0]
            let g = components[1]
            let b = components[2]
            return  String(format: "%02X%02X%02X", (Int)(r * 255), (Int)(g * 255), (Int)(b * 255))
        }
        return nil
    }
}

extension String {
    var html2Attributed: NSAttributedString? {
        do {
            guard let data = data(using: String.Encoding.utf8) else {
                return nil
            }
            return try NSAttributedString(data: data,
                                          options: [.documentType: NSAttributedString.DocumentType.html,
                                                    .characterEncoding: String.Encoding.utf8.rawValue],
                                          documentAttributes: nil)
        } catch {
            print("error: ", error)
            return nil
        }
    }
    
    var htmlAttributed: (NSAttributedString?, NSDictionary?) {
        do {
            guard let data = data(using: String.Encoding.utf8) else {
                return (nil, nil)
            }

            var dict:NSDictionary?
            dict = NSMutableDictionary()

            return try (NSAttributedString(data: data,
                                          options: [.documentType: NSAttributedString.DocumentType.html,
                                                    .characterEncoding: String.Encoding.utf8.rawValue],
                                          documentAttributes: &dict), dict)
        } catch {
            print("error: ", error)
            return (nil, nil)
        }
    }
    
    func htmlAttributed(using font: UIFont, color: UIColor, lineHeight: CGFloat) -> NSAttributedString? {
        do {
            let htmlCSSString = "<style>" +
                "html *" +
                "{" +
                "font-size: \(font.pointSize * 0.75)pt !important;" +
                "color: #\(color.hexString!) !important;" +
                "font-family: \(font.familyName), Helvetica !important;" +
                "line-height: \(lineHeight * 0.06) !important;" +
                "}</style> \(self)"

            guard let data = htmlCSSString.data(using: String.Encoding.utf8) else {
                return nil
            }

            return try NSAttributedString(data: data,
                                          options: [.documentType: NSAttributedString.DocumentType.html,
                                                    .characterEncoding: String.Encoding.utf8.rawValue],
                                          documentAttributes: nil)
        } catch {
            print("error: ", error)
            return nil
        }
    }
}

And the implementation in label:

descriptionLabelText.attributedText = description.htmlAttributed(using: UIFont.gibsonRegular.withAdjustedSize(16),
                                                                    color: .greyscale800,
                                                                    lineHeight: 20.adjusted)
