How to use the new text renderers APIs introduce in 2024?

To use the new text renderer APIs introduced in 2024, you can follow these steps as outlined in the session "Create custom visual effects with SwiftUI":

1. Implement the Text Renderer Protocol: The core of the text renderer protocol is the drawLayout method. This method takes two arguments: textLayout and graphicsContext. The textLayout allows access to individual components of the text, such as lines, runs, and glyphs, while the graphicsContext is used for drawing.

2. Iterate Over Text Layout: For a minimal text renderer, iterate over the individual lines of the layout using a for loop and draw them into the context. This provides the default rendering behavior.

3. Animate Text: To animate text, add properties to your text renderer such as elapsed (time passed), elementDuration (time for animating a line or character), and totalDuration (total animation time).

4. Use the Text Attribute Protocol: Introduced alongside the text renderer, this protocol allows you to pass data from your text to your text renderer. You can apply custom attributes to text using the customAttribute text modifier.

5. Create Custom Transitions: Implement custom transitions by using the text renderer to animate text. You can use the textRenderer view modifier to set your custom renderer.

For more detailed guidance, you can refer to the session Create custom visual effects with SwiftUI (12:49) which covers text transitions.
