The most powerful animation feature introduced in iOS 17 is keyframe animation. We can implement keyframe animations with the KeyframeAnimator
container. This container allows us to perform animations frame by frame. It is a very advanced feature and requires a deep understanding of animation techniques or animation software to generate the keyframe values for us. This is outside the scope of this book.
Alternatively, we can use the keyframeAnimator(initialValue:repeating:content:keyframes:)

In this recipe, we will show how to use the KeyframeAnimator
container.

How to do it…
To illustrate how the KeyframeAnimator
container works, we will include a couple of images and we will animate some of the properties:
