We can add many models in the Reality Composer Pro scene, but when I use RealityView to display and add modifiers in SwiftUI, the modifiers will have Effect, and I don't want to do this. I hope this modifier will be valid for a single model in the Reality Composer Pro scenario. May I ask how to add modifiers to a single model in the Reality Composer Pro scene?

I learned Sharplay from the WWDC video. I understand the creation of seats, but I can't learn some of the following contents well, so I hope you can help me. The content is as follows: I have set up the seats. struct TeamSelectionTemplate: SpatialTemplate { let elements: [any SpatialTemplateElement] = [ .seat(position: .app.offsetBy(x: 0, z: 4)), .seat(position: .app.offsetBy(x: 1, z: 4)), .seat(position: .app.offsetBy(x: -1, z: 4)), .seat(position: .app.offsetBy(x: 2, z: 4)), .seat(position: .app.offsetBy(x: -2, z: 4)), ] } It was mentioned in one of my previous posts: "I hope you can give me a SharePlay Button. After pressing it, it will assign all users in Facetime to a seat with elements quantified in TeamSe lectionTemplate.", and someone replied to me and asked me to try systemCoordinator.configuration.spatialTemplatePreference = .custom (TeamSelectionTemplate()), however, Xcode error Cannot find 'systemCoordinator' in scope How to solve it? Thank you!

When I wanted to call the Reality Composer Pro scene containing Object Tracking, I tried the following code: RealityView { content in if let model = try? await Entity(named: "Scene", in: realityKitContentBundle) { content.add(model) } } Obviously, this is wrong. We need to add some configurations that can enable Object Tracking to Reality View. What do we need to add? Note:I have seen https://developer.apple.com/videos/play/wwdc2024/10101/, but I don't know much about it.

I followed the WWDC video to learn Sharplay. I understood the first creation of seats, but I couldn't learn some of the following content very well, so I hope you can give me a list code. The contents are as follows: I have already taken a seat. struct TeamSelectionTemplate: SpatialTemplate { let elements: [any SpatialTemplateElement] = [ .seat(position: .app.offsetBy(x: 0, z: 4)), .seat(position: .app.offsetBy(x: 1, z: 4)), .seat(position: .app.offsetBy(x: -1, z: 4)), .seat(position: .app.offsetBy(x: 2, z: 4)), .seat(position: .app.offsetBy(x: -2, z: 4)), ] } I hope you can give me a SharePlay Button. After pressing it, it will assign all users in Facetime to a seat with elements quantified in TeamSelectionTemplate. Thank you very much.

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

I saw onnoffitacation in the Behavior configuration of Reality Composer pro, which asked me to enter the Nofficatition name, that is to say, this requires swift in Xcode to send a message. There is a message name in the message, so I hope you can write an list for me how to use Swift in Xcode to send a message containing the message name.

Please treat me as a beginner of Unity. Now I want to learn to develop visionOS VR App through unity. I try to find a relatively complete route and start learning, but Unity's official website does not have much explanation for visionOS VR App, so I hope you can give me a comparison. The whole route, thank you!

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.

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)

In visionOS, I want show a 3D Content, I can use RealityView or Mode3D, But the effect they achieve is similar. What is the difference between them and which one to use for users?

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?

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!

Apple launched the Developer Strap on the developer's official website, which allows developers to connect Vision Pro and Mac with USB-C, but I can't get it in China, so I want to ask developers who already have Vision Pro or People who understand these questions: Can Vision Pro without Developer Strap be debugged wirelessly? If so, How is the experience of unlimited debugging? and how does it compare with wired connection? Thank you!

I found in App Store Connect that on the 18th (Vision Pro pre-sale day), my visionOS App was purchased by a person in the United States, but this day was only pre-sale. No one really got Vision Pro, and this app is only compatible with visionOS. May I ask why?
