# init(markdown:options:baseURL:)

Creates an attributed string from Markdown-formatted data using the provided options.

## Declaration

convenience init(markdown: Data, options: AttributedString.MarkdownParsingOptions = .init(), baseURL: URL? = nil) throws
```

## Parameters

- `markdown`: The doc://com.apple.foundation/documentation/Foundation/Data instance that contains the Markdown formatting.
- `options`: Options that affect how the initializer interprets formatting in the Markdown string. This parameter defaults to no options.
