To improve the smoothness of your app, you can focus on reducing friction and optimizing performance. Here are some key points from various WWDC sessions that can help:
-
Reduce Friction:
- App Intents: Use App Intents to bring your app's core features closer to users, reducing the need for them to switch between apps. This can help maintain a smooth flow and reduce friction. For more details, you can refer to the session Bring your app’s core features to users with App Intents.
- Widgets and Controls: Allow users to add widgets and controls to their home screen or control center, making important actions from your app easily accessible. This personalization can enhance the user experience and keep the app usage fluid (Bring your app’s core features to users with App Intents).
-
Optimize Performance:
- 3D Assets: If your app involves 3D assets, ensure you optimize them for spatial computing. This includes managing polygon count, efficient texture use, and optimizing materials. For example, keep the polygon count to no more than 500,000 triangles for better performance (Optimize your 3D assets for spatial computing).
- Rendering and Performance: For apps on Vision Pro, consider the GPU workload and optimize accordingly. Non-immersive scenes may render faster than immersive ones, so test early and often to find performance bottlenecks (Optimize your 3D assets for spatial computing).
-
Responsive UI:
- CarPlay: Ensure your app's UI is responsive and updates in real-time to user interactions. Delayed responses can disrupt the smoothness of the experience (Meet the next generation of CarPlay architecture).
-
Design Considerations:
- Hover Effects: In VisionOS, use hover effects to provide visual feedback and make interactions more intuitive. Ensure interactive elements have sufficient tap targets to avoid frustration (Design great visionOS apps).
By focusing on these areas, you can significantly improve the smoothness and overall user experience of your app. For more detailed guidance, you can explore the following sessions:
