What did you do?

                        if let m = chat.message
                           , let font = UIFont(name: "Lato-Regular", size: 20.0)
                        {   
                            let markdownParser = CDMarkdownParser(font: font)
                        }

What did you expect to happen?

No crash

What happened instead?

Crash in CDFont+CDMarkdownKit.swift, line 57. Unexpectedly found nil when unwrapping optional value.

CDMarkdownKit Environment

CDMarkdownKit v2.1.1
xcode 12.5.1
swift v5.0
iOS Simulator
macOS 11.4

This is the CDMarkdownKit code that crashed, it crashed on the force unwrap of "descriptor" variable.

private func withTraits(_ traits: CDFontDescriptorSymbolicTraits...) -> CDFont {
    let descriptor = fontDescriptor.withSymbolicTraits(CDFontDescriptorSymbolicTraits(traits))
    return CDFont(descriptor: descriptor!,
                  size: self.pointSize)
}

Thanks for pointing this out @mathist . I'll take a look

Still crashing on this line.

let parser = CDMarkdownParser(font: textFont, backgroundColor: UIColor.clear)
