Maintain rotation sense while dragging
Hi, I heve a problem with an visionOS app and I couldn't find a solution. I have 3D carousel with cards and when I use the drag gesture and I drag to the left I want the carousel to rotate clockwise and when I drag to the right I want the carousel to rotate counter clockwise. My problem is when I rotate my body more than 90 degrees to the left or to the right the drag gesture changes it's value and the carousel rotates in the opposite direction? Do you know how can I maintain the right sense taking into account that the user can rotate his body? I've tried to take the user orientation with device tracking and check if rotation on Y axis is greater than 90 degrees in both direction but It is a very small area bettween 70-110 degrees when it still rotates in the opposite direction. I think that's because the device traker doesn't update at the same rate as drag gesture or it doesn't have the same acurracy.

Volumetric Windwos anchores
Hi, we would like to create something where you can open multiple volumetric windows and place them in a room, our biggest issue is that we want these windows to be persistent, so when I close and reopen the app, the windows to be in the same position. We can't use immersive spaces because we also want to have the possibility to access the shared space. Is it possible with the current features and capabilities to do that? If yes do you have some advices how can we achieve this? The alternative is if is it possible to open the virtual display in immersive spaces or if we have the possibility to implement our own virtual display.

Persistent Entity Position
I want to let users place 2D/3D “artworks” on detected walls and have them reappear in exactly the same real‑world spot after quitting and relaunching the app (like widgets do, but for my own entities).Environment: Xcode 26, visionOS 2.0, RealityKit + ARKitSession/WorldTrackingProvider Entities are parented to a holder that’s aligned to a wall via plane/mesh raycasts. What I’ve tried: Create a WorldAnchor at placement, save UUID + full 4×4 transform On next launch, re-create the WorldAnchor (or set the saved transform) and attach the entity Gate restore on relocalization/mesh updates and disable all raycast/search after restore Issue: After relaunch, placement still resolves relative to current device pose, not the same wall position. Questions: Is there a public API in visionOS 2.0 to persist app‑managed world anchors across sessions (room‑fixed), e.g., AnchorStore or equivalent? If not, what’s the recommended pattern to reliably restore wall‑anchored content? Are persistence features mentioned for widgets/windows available to third‑party RealityKit entities?

Hover Effect & Tap Problem
Hi, since I updated my device to visionOS 2.0 or higher I have some problems with my app. Sometimes when I go with my eyes over buttons or the tabview which is a SwiftUI component that many apps use, the hover effect doesn't trigger anymore, I can tap on the icon from the tabview but doesn't extend when I hover it to se the description of the button. It is weird because it doesn't happen all the time. But in VisionOS 1.0 doesn't happen at all. My second issue is that I have an navbar as an attachment and this attachment has a draggable modifier that we created. The buttons are not tappable until I drag the navbar a little, this also never happened in VisionOS 1.0 but always happen in Vision 2.0+ because I've tested in the simulator with different versions. Is it possible these problems to be related to handTracking Service that we use from ARKit? Because sometimes when we close the trackers the app works as intended.
