Issue with Attributed text and scalability

[MahmoudZinji]

• This is how i use SwiftyMarkdown in my code

subTitleLabel.attributedText = NSAttributedString.from(markupString: viewModel.subTitle ?? "", baseFont: UIFont.NewDesign.textPrimary)

• And i call this func in the below extension

extension NSAttributedString {
    static func from(markupString: String,
                     baseFont: UIFont = .NewDesign.textPrimary,
                     color: UIColor = UIColor.NewDesign.graphiteBlack) -> NSAttributedString {
        let markdownString = SwiftyMarkdown(string: markupString)
        markdownString.setFontNameForAllStyles(with: baseFont.fontName)
        markdownString.setFontSizeForAllStyles(with: baseFont.pointSize)
        markdownString.setFontColorForAllStyles(with: color)
        markdownString.body.alignment = .center

        return markdownString.attributedString()
    }
}

• What i expect if something like

abc def ghi **BoldAttributedString** jkl mno pgr

when i change text size from setting and switch back to my screen all the abc letters adjust except the Attributed one

if i start my app with big text size the attributed is big but not as other texts, not as supposed to be

here below is the font thet i use as an example

extension UIFont {
    struct NewDesign {
        
        static var textPrimary: UIFont {
            UIFont(name: "Asap-Regular", size: 16.0)!.scaledFont
        }
}
}

the scaling is not as supposed to be

Any idea why is this happening
