How do you synchronize metal animation with uikit animations?

To synchronize Metal animations with UIKit animations, you can leverage the new APIs introduced in iOS 18 that enhance the interoperability between SwiftUI and UIKit. Specifically, you can use SwiftUI animation types to animate UIKit views, ensuring that animations run perfectly in sync across framework boundaries.

Here are the steps to achieve this:

1. Use SwiftUI Animation Types: You can now use SwiftUI animation types to animate UIKit views. This allows you to take advantage of the full suite of SwiftUI animations, including custom animations.

2. Bridge Animations: Utilize the new animate function on UIView and NSAnimationContext to bridge animations started in SwiftUI into UIKit. This ensures that animations run in sync even across different frameworks.

3. Preserve Velocity: For gesture-driven animations, SwiftUI automatically preserves velocity, which can be beneficial for creating fluid animations that respond to user interactions.

For a detailed explanation and examples, you can refer to the session Enhance your UI animations and transitions (11:19).
