SwiftUI: which Markdown specification is supported?

SwiftUI’s Markdown support is really Foundation.AttributedString’s Markdown support, so I would recommend you add the “Foundation” tag to this question so the team who can answer it will find it.

Yes, it is GitHub flavored markdown. AttributedString converts both inline and block styles. SwiftUI renders inline styles (but not images at this time). We use the fantastic cmark-gfm library to parse the markdown string.

I can get to the code blocks if I do this:

var aString: AttributedString = try? AttributedString(markdown: m)

for r in aString.runs {
    if let pi = r.presentationIntent {
        for i in pi.components {
        }
    }
}

But - then I lose all the new line characters in my initial string.

So I can preserve the new line characters like this:

var aString: AttributedString = try? AttributedString(markdown: m, options: AttributedString.MarkdownParsingOptions(interpretedSyntax: .inlineOnlyPreservingWhitespace))

But - now there are no code block annotations.

Is there a way that I can preserve new lines AND get code block annotations? I need the code block annotations so I can set my own formatting. (At least until Apple renders code blocks properly).

Any solution for this yet? I am trying add indentation to my paragraph lines which is not being rendered either.

    let paragraphStyle = NSMutableParagraphStyle()
    paragraphStyle.lineBreakMode = .byWordWrapping
    paragraphStyle.firstLineHeadIndent = 20
    paragraphStyle.lineSpacing = 0
    paragraphStyle.headIndent = 20
    return paragraphStyle
