Many animations for focus, selection, and transitions are built right into the Apple TV platform from UIKit, letting you take advantage of them in your own apps. These subtle animations create a visual sense of connection between people and the content on the screen. Use built-in animations in combination with tasteful custom animations to enhance immersion in your content.
Use animation only in response to a user action. Animation that’s not a direct result of an action can make people feel disconnected or distracted. Don’t use animation just for the sake of using animation.
Avoid animations with excessive movement. Animations with superfluous bounce or spring effects may look great on your computer screen, but they can be annoying when projected over a much larger area. Use gentle, easing animated effects instead. Always test your designs to make sure they look great on an actual TV.
Strive for realism and credibility. The design language of Apple TV is light and airy; its key user interface components are made to appear thin and lightweight. Elements that look lightweight shouldn’t act like they have mass by bouncing into place or springing out of place. People tend to accept artistic license, but they can feel disoriented when movement doesn’t make sense or appears to defy physical laws.
Make animations optional. When the option to reduce motion is enabled in accessibility preferences, your app should minimize or eliminate application animations. For guidance, see Motion.
