To use AttributedString in your app, you can refer to several sessions from WWDC that cover different aspects of working with attributed strings. Here are some key points and sessions that might help:
-
Custom Visual Effects with SwiftUI:
- You can implement custom text attributes using the new text attribute protocol introduced alongside the text renderer in iOS 18. This allows you to pass data from your text to your text renderer and apply custom attributes to specific ranges of text.
- Example: Marking words with a custom emphasis attribute and iterating over the text layout to apply effects.

-
Build Multilingual-Ready Apps:
- You can add color attributes to an attributed string to highlight parts of the text. This is useful for differentiating text without relying on font weight, which may not be supported in all languages.
- Example: Highlighting search results using color attributes.

What’s New in AppKit:
- Text highlighting can be controlled using attributed string attributes. The new
texthighlightattribute corresponds to atexthighlightstyle, which can be set to system default or customized with a color scheme. - Example: Using the app's accent color for text highlighting.

Bring Expression to Your App with Genmoji:
- You can decompose and recompose attributed strings to include image glyphs, which can be displayed in various contexts, including HTML.
- Example: Adding a Genmoji to a title and displaying it in a web interface.
