A simple proof-of-concept SwiftUI library that renders a HTML-like language using SwiftUI Text elements.


Goal of this project is to test the described proof-of-concept. In the moment both the parser and the renderer are fairly buggy. The language used is closely related to HTML and those comfortable with HTML should also be comfortable with this language. The string is parsed into an abstract sytnax tree consisting of Tag structs. The tree is then rendered to SwiftUI native Text views.

Use Cases

  • Formatted localized strings
  • Loading text from a database
  • Allowing the user to format text in a certain way



The following tags are implemented:

  • largeTitle / h1
  • title / h2
  • headline / h3
  • subheadline / h4
  • body
  • callout / h5
  • caption / h6
  • footnote
  • b
  • i
  • u
  • br
  • font
    • Attributes:
      • family
      • size
      • color
    • family and size attributes both have to be present for them to have any effect
    • color can only be given using hex values i.e. #ff0000 and #ff0000aa

Block elements like h1/h2/h3/h4/h5 are not implemented in the moment. Newlines can only be added using \n and <br/>

The XML-like parser is very rudimentary and does not follow any specs. Unlike in HTML every tag that was opened has to be closed - this includes <br/>.

👉 This is just a proof-of-concept that should not be used in any application



import SwiftUI
import SwiftUIFormattedText

struct ContentView : View {
    @State var string: String = "Type some text here..."
    var body: some View {
        VStack {
            FormattedText(formatted: string)
        .frame(maxWidth: .infinity, maxHeight: .infinity)


<h1>This is a h1</h1><br/>
<largeTitle>This is a largeTitle</largeTitle><br/>
<h2>This is a h2</h2><br/>
<title>This is a title</title><br/>
<h3>This is a h3</h3><br/>
<headline>This is a headline</headline><br/>
<h4>This is a h4</h4><br/>
<subheadline>This is a subheadline</subheadline><br/>
<h5>This is a h5</h5><br/>
<callout>This is a callout</callout><br/>
<h6>This is a h6</h6><br/>
<caption>This is a caption</caption><br/>
<body>The meaning of body is different compared to HTML</body><br/>
<footnote>This is a footnote</footnote><br/>
<i>This text is italic and this is <b>bold.</b></i><br/>
<u>This text should appear underlined.</u><br/>
<font color="#ff0000">This text should appear in red</font><br/>
Text can also wrap multiple lines:<br/>
