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.

In iOS, to display a RealityView, you can assign a value to the content.camera property: content.camera = .virtual However, how can this be implemented in macOS and tvOS?

There appears to be an issue with the sales of my application. The sales table indicates a negative value of -1. Has anyone processed a refund for this transaction?

Hello, I would like to inquire about the release date of Swift Assist’s beta version. Apple has stated that it will be released later this year, but they have not provided a specific date or time. Could you please provide information on the beta version’s release date? Additionally, is there a trial version available? If so, when was it released? Thank you for your assistance.

This effect was mentioned in https://developer.apple.com/wwdc24/10153 (the effect is demonstrated at 28:00), in which the demonstration is you can add coordinates by looking somewhere on the ground and clicking., but I don't understand his explanation very well. I hope you can give me a basic solution. I am very grateful for this!

Coordinate conversion was mentioned in https://developer.apple.com/wwdc24/10153 (the effect is demonstrated at 22:00), in which the demonstration is an entity that jumps out of volume into space, but I don't understand his explanation very well. I hope you can give me a basic solution. I am very grateful for this!

In this code: https://developer.apple.com/documentation/visionos/incorporating-real-world-surroundings-in-an-immersive-experience It contains a physical collision reaction between virtual objects and the real world, which is realized by creating a grid with physical components. However, I don't understand the information in the document very well. Who can give me a solution? Thank you!

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?

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?

Apple Intelligents is here, but I have some problems. First of all, it often shows that something is being downloaded on the settings page. Is this normal? And the Predictive Code Completion Model in Xcode seems to have been suddenly deleted and needs to be re-downloaded, and the error The operation couldn't be complet has occurred. Ed. (ModelCatalog.CatalogErrors.AssetErrors error 1.), detailed log: The operation couldn’t be completed. (ModelCatalog.CatalogErrors.AssetErrors error 1.)

In RealityView I have two entities that contain tracking components and collision components, which are used to follow the hand and detect collisions. In the Behaviors component of one of the entities, there is an instruction to execute action through onCollision. However, when I test, they cannot execute action after collisions. Why is this?

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!

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?

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.

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)
