If your Markdown have check boxes, you can provide a Binding string.

@State var text = """

"""

MarkdownView(text: $text)

Further Customization

Font

You can set custom fonts or change text styles.

MarkdownView(text: "# H1 title")
    .font(.largeTitle.weight(.black), for: .h1)

Tint

Default tint color for code blocks and block quotes is the accent color.

You can customize them explicitly.

MarkdownView(text: "> Quote and `inline code`")
    .tint(.pink, for: .inlineCodeBlock)

Add Custom Providers

You can add your custom image providers and block directive providers to display your content.

To do that, first create your provider.

struct CustomImageProvider: ImageDisplayable {
    func makeImage(url: URL, alt: String?) -> some View {
        AsyncImage(url: url) {
            switch $0 {
            case .empty: ProgressView()
            case .success(let image): image.resizable()
            case .failure(let error): Text(error.localizedDescription)
            @unknown default: Text("Unknown situation")
            }
        }
    }
}

Then apply your provider to MarkdownView.

MarkdownView(text: markdownText)
    .imageProvider(CustomImageProvider(), forURLScheme: "my-image")

The implementation of the block directive is exactly the same way.
