To create a hover effect in visionOS, you can use the new custom hover effect API introduced in visionOS. This API allows SwiftUI views to respond when users look at them, providing feedback about which element will be triggered when users interact with it. Here's a brief overview of how to implement hover effects:
-
Standard Hover Effects: These are automatically added to standard controls and can be added to custom controls using the
hoverEffectview modifier. For more about standard effects like highlight, you can refer to the session "Elevate your windowed app for spatial computing." -
Custom Hover Effects: Some views benefit from custom effects. For example, sliders can show a knob to invite interaction, buttons can grow to show the name of the previous page, and tab bars can pop open to show labels. With the custom hover effect API, you can build effects like these and apply them to SwiftUI views anywhere in your app, including ornaments and reality view attachments.
-
Privacy Considerations: Custom hover effects are designed to preserve privacy. They are applied by the system outside the app process without requiring extra entitlements or extensions.
-
RealityKit Integration: RealityKit also has a new API to apply hover effects to 3D content. You can use shader-backed hover effects for more flexibility, allowing you to control exactly how your entities look on hover.
For more detailed guidance, you can watch the session Create custom hover effects in visionOS.
