How do I animate a label

To animate a label in SwiftUI, you can use the techniques discussed in the session "Create custom visual effects with SwiftUI." Here are the steps you can follow:

Implement the Animatable Protocol: This allows you to animate the elapsed time value. You can forward the animatableData property to the elapsed time.
Calculate Delays and Start Times: Calculate the delay between consecutive lines and their relative start times based on their index and delay value.
Update Graphics Context: Create a copy of the current graphics context to ensure individual calls to your helper function do not affect each other.
Animate Properties: Update the properties of the graphics context that you want to animate. For example, you can animate the opacity and blur radius to give the impression that the text is manifesting from a diffuse state.
Custom Transition: Implement a custom transition to animate the text. You can use a spring animation on the y-axis and adjust the blur radius based on the line's typographic bounds.

For a detailed explanation and code examples, you can refer to the session Create custom visual effects with SwiftUI (12:49).
