What shall I use for complex animations?

For complex animations, you have several options depending on the type of animation you are looking to create:

1. SwiftUI Animations: SwiftUI provides a robust set of tools for creating animations. You can use SwiftUI animations to animate UIKit and AppKit views, which can simplify your code and make your animations feel smoother. For more details, you can refer to the session Enhance your UI animations and transitions (11:48).

2. Reality Composer Pro: If you are working with 3D content, Reality Composer Pro offers a variety of tools for creating complex animations. You can use the built-in Actions API to create and sequence animations, or use custom actions for more specific needs. For example, you can create animations for characters using inverse kinematics or blend shape animations for lifelike movements. For more details, you can refer to the session Compose interactive 3D content in Reality Composer Pro (22:55).

3. Blend Shape Animations: These are particularly useful for animating characters' faces or bodies by blending between different shapes. This technique allows for smooth transitions and lifelike movements. For more details, you can refer to the session Compose interactive 3D content in Reality Composer Pro (27:23).

4. Text Transitions in SwiftUI: If you are looking to animate text, SwiftUI provides tools to create custom visual effects and transitions. You can implement the Animatable protocol to automatically animate properties like elapsed time. For more details, you can refer to the session Create custom visual effects with SwiftUI (12:49).
