SwiftUI Text Markdown dynamic string not working

by

Short Answer

Wrap the string in AttributedString(markdown: my_string_here):

let string: String = "[Apple Link](http://www.apple.com)"
Text(try! AttributedString(markdown: string))

Extension

extension String {
  func toMarkdown() -> AttributedString {
    do {
      return try AttributedString(markdown: self)
    } catch {
      print("Error parsing Markdown for string \(self): \(error)")
      return AttributedString(self)
    }
  }
}

Long Answer

SwiftUI Text has multiple initializers.

For String:

init<S>(_ content: S) where S : StringProtocol

For AttributedString:

init(_ attributedContent: AttributedString)

When you declare a static string, Swift is able to guess whether the intent is to use a String or AttributedString (Markdown). However, when you use a dynamic string, Swift needs help in figuring out your intent.

As a result, with a dynamic string, you have to explicitly convert your String into an AttributedString:

try! AttributedString(markdown: string)
