Is there a way of converting AttributedString or NSAttributedString to Markdown?

Is it possible to change the width of the HR produced by the PresentationIntent.Kind.thematicBreak ?

Not all markdown elements work. The string will work if I do: "hello world" Italics "hello world" Bold But NOT "hello world" Bold & Italics There are others that also don't work such as headers and numbered lists.         let string: String = "***hello world***"         if let attributedString: AttributedString = try? AttributedString(markdown: string) {             let attributedText: NSMutableAttributedString = NSMutableAttributedString(attributedString)             myLabel.text = nil             myLabel.attributedText = attributedText         }
