I want to play RealityKitContent USDA model's Spatial Audio, I use this code: RealityView{ content in do { let entity = try await Entity(named: "isWateringBasin", in: RealityKitContent.realityKitContentBundle) let audio = entity.spatialAudio entity.playAudio(audio) content.add(entity) } catch { print("Entity encountered an error while loading the model.") return } } entity.playAudio(audio) this code need add a 'AudioResource' back of audio, Excuse me, what should AudioResource be?

In a visionOS app project, how to fix a view in the user's hand through ARKit.

Is Persona open to developers? If it is open, in which document does it describe the information about Persona?

Just now, we learned the exciting news that Vision Pro is about to be released! I would like to ask if there are any services such as discounts or rentals for developers? If so, can I experience it normally in China?

In RealityView, I use AnchorEntity to lock to Wall to run normally: AnchorEntity(.plane(.vertical, classification: .wall, minimumBounds: .one)) But I use a location other than wall but I can't display View. Why is that?

We can use AnchorEmpty to fix RealityView in one place, such as a wall. Now I hope that it can not only be fixed in one place, but also fill the whole place with RealityView by stretching. For example: My RealityView is a picture, which is now anchored to the wall, and ARKit will stretch the picture according to the size of the wall. How to achieve the whole wall? Thank you!

In order to improve App sales, I hope to promote App. At present, I only know from the VisionOS App Submission Guide that I can get the opportunity to become an editor's choice to promote the App by sharing my APP. Is there any other way to promote VisionOS App?

I hope to send my income to my Apple Cash (Apple Cash can display the virtual card number in iOS 17.4 Beta). Is this okay? If you can, how to fill in questions such as ABA Routeing Number in Agreements, Tax, and Banking? And will Apple Cash give me interest (I only have Apple Cash)

I want to test the in-app purchase in visionOS Simulator. I logged in to the Sandbox account in Simulator and was prompted to send the verification code to the phone number I wrote in the previous step. I entered the verification code accurately, but I couldn't log in normally. It was wet many times.

How to display the user's own persona in a view

In the AudioServicesPlaySystemSound function of AudioToolbox, you can enter the corresponding SystemSoundID to play some sound effects that come with the system. However, I can't be sure what sound effect each number corresponds to, so I want to know all the sound effects in visionOS and its corresponding SystemSoundID.

In a listing program in WWDC24, it shows that users can control the robot to walk by pinching and sliding. However, I haven't found any documents or videos related to this function. If you know, please let me know. Thank you!

I was making a gesture to let the goose (character) walk, but I had two problems. 1: I added collision and physical body components to the goose and the collided entity, but I found that those physical formations could not completely block the way of the goose. For example, a tree is in front of it. After the goose is blocked, it will cross the tree or run to the top of the tree as long as it is a little faster. 2: Because the knowledge I have accumulated is not very complete, I can control the movement of the goose on the z-axis. I hope that the user's gestures can be realized by dragging back and forth (z-axis), but I can only realize the user's gestures by dragging up and down (y-axis). I hope you can give me some guidance: GooseOriginalPosition.z + Float(translation.height / 10000) This is the complete code: @State var goose: Entity? @State var isDraggingGoose = false @State var gooseOriginalPosition = SIMD3<Float>(repeating: 0) RealityView { content in if let model = try? await Entity(named: "WorldScene", in: realityKitContentBundle) { content.add(model) } if let gooseEntity = try? await Entity(named: "Goose", in: realityKitContentBundle) { gooseEntity.scale = SIMD3<Float>(repeating: 0.3) content.add(gooseEntity) goose = gooseEntity } } .simultaneousGesture(DragGesture() .targetedToAnyEntity() .onChanged { value in handleDrag(value) } .onEnded { _ in isDraggingGoose = false gooseTimer?.invalidate() }) func handleDrag(_ value: EntityTargetValue<DragGesture.Value>) { guard let goose = goose else { return } if !isDraggingGoose { isDraggingGoose = true gooseOriginalPosition = goose.position(relativeTo: nil) } let translation = value.gestureValue.translation let newPosition = SIMD3<Float>( gooseOriginalPosition.x + Float(translation.width / 10000), gooseOriginalPosition.y, gooseOriginalPosition.z + Float(translation.height / 10000)//I hope the gesture here should be z-axis drag. ) goose.setPosition(newPosition, relativeTo: nil) }

Apple Intelligence is now available in macOS 15.1 and iOS 18.1 (Beta). However, it is currently not supported on visionOS. Despite the fact that visionOS runs on M2 silicon with 16GB of unified memory, Apple Intelligence cannot be utilized on this platform. I want enable Apple Intelligence for my visionOS app.

I am honored that I successfully participated in the "Envision the future: Build great apps for visionOS"(https://developer.apple.com/events/view/ZCH7ZUY24C/dashboard) conference. However, unfortunately, I am in China, and due to the visa problem (because it usually takes at least 2 months to apply for a visa, but it only takes about 10 days from the time I received the notice to the meeting), I can't go to the United States to participate in the site. So I hope Apple can place an iPad on site and create a FaceTime link, and then I can make a call to this iPad. I also told Apple about this suggestion, but now there are only a few days left to start. They didn't reply to me. Even Apple has sent me the ticket to the Developer Center and asked me to add it to the Apple Wallet App, which means that Apple has not There is a request to deal with me. So I hope you can give me some advice or help me for those who know about this aspect. For Apple's internal engineers, if possible, I hope you can contact the person who manages this meeting. I'm very grateful for this. Thank you.
