When I run my visionOS App, RealityKitContent Report an error： Tool terminated by signal 'Segmentation fault: 11' And it points to a USDZ model I imported, but in the scene, my model can be displayed normally and there is no damage. Why does an error occur? How can I check and repair it?

I used such a gesture under a reality view. DragGesture().targetedToAnyEntity() .onChanged { value in print("DragGesture") self.dragOffset = value.translation self.startTimer() } .onEnded { _ in self.dragOffset = .zero self.direction = "None" self.stopTimer() } However, due to the special nature of Reality View, it is impossible to detect gestures normally, so I think some modifiers should be added after value.translation, but I don't know what modifiers are. Can you give me some? Do you know? Thank you.

How to realize that a string of descriptions of a view will appear after looking at a view for a long time in the diagram

In a scenario involving one of the entities in a Reality Composer Pro environment, I intend for this entity to display a blue material when viewed by the user. To achieve this, I have added the following Shader Graphs to the materials associated with this entity: Additionally, I have included the HoverEffectComponent component to the Reality View in the code: RealityView { content in if let model = try? await Entity(named: “WorldScene”, in: realityKitContentBundle) { let hoverEffect = HoverEffectComponent(.shader(.default)) model.components.set(hoverEffect) content.add(model) } } However, hover this entity, I am unable to observe any visual reaction. Could you please provide guidance on how to resolve this issue?

I have developed a code that initiates the Timeline in the Reality Composer Pro scene every 12.93 seconds. RealityView { … } .onAppear { startTimer() } .onDisappear { stopTimer() } func startTimer() { timer = Timer.scheduledTimer(withTimeInterval: 12.93, repeats: true) { _ in action() } } func stopTimer() { timer?.invalidate() } func action() { print(“SunUpDown”) NotificationCenter.default.post( name: NSNotification.Name(“RealityKit.NotificationTrigger”), object: nil, userInfo: [ “RealityKit.NotificationTrigger.Scene”: scene as Any, “RealityKit.NotificationTrigger.Identifier”: “SunUpDown” ] ) } Upon receiving the “SunUpDown” command, Timeline will be executed. However, everything was functioning normally when I was running the scene, and I could continue looping until I attempted to zoom in on the window and discovered that it ceased looping. Could you please provide an explanation for this behavior? Note: The window type is volumetric, and the parameter of the defaultWorldScaling modifier is dynamic.

During testing, I encountered an issue with SharePlay. Since SharePlay necessitates multi-device testing, I intend to use my Mac and Vision Pro for testing. However, since these two devices are also my primary devices, I am reluctant to switch Apple IDs for testing purposes. Instead, I would like to test the original Apple ID. However, since both devices belong to the same Apple ID and rely on the same phone number, they are unable to FaceTime each other. I am at a loss as to how to proceed.

I am attempting to execute actions after clicking an entity in Reality View using the Behaviors component. I have added the Input Target component and the Tap gesture as follows: TapGesture().targetedToAnyEntity() .onEnded({ value in _ = value.entity.applyTapForBehaviors() }) ) However, during testing, I have observed that the entity does not appear to recognize the click gesture. Could you kindly provide any relevant documentation or guidance on this matter?

In the reality view, I found that the entity could not cast a shadow on the reality. What configuration should I add to achieve this function?

In my Volume, there is a RealityView that includes lighting effects. However, when the user drags the position of the window back and forth, the farther the distance between the volume and the user, the greater the brightness of the light effect. ( I believe this may be a Beta version of a bug.) Note: The volume windowGroup has the .defaultWorldScaling(.dynamic) property.

The entity in My RealityView contains tracking components and allows them to track different places of the hand. However, I found that except for the fingertip of the index finger, the fingertip of the thumb, the palm and the wrist, all other positions cannot be tracked normally (such as the fingertip of the middle finger). How can I solve it (I think it may be a beta version of the bug)

In visionOS2, there exists a function that enables users to raise their hand to display the home button. However, this functionality conflicts with the interaction required for the mixed display space utilized within my application. Therefore, I seek a method to disable this functionality.

I can execute an action by allowing Xcode to send a notification to Reality Composer Pro via NotificationCenter, or I can send notifications to Xcode through the Notification Action in Reality Composer Pro. However, I discovered that they were unable to accept notifications from both parties within my project. To ascertain whether there was an error in my code, I created a simple Demo project. I utilized the same code and determined that it functioned normally within the Demo project. It is perplexing that I am unable to resolve this issue. Do I require additional modifications?

Is there any action that can clone the entity in RealityView to the number I want? If there is, please let me know. Thank you!

The light of RealityView can only be effective on virtual objects. I hope it can be projected into the real world. What API can be implemented?

In Reality View, I want to move an entity A to the position of entity B, but I can't determine the coordinates of entity B (for example, entity B is tracking the hand). What's the solution?
