At the Hobo Nichi Hackathon, held over two days on April 13 and 14, I joined Team 1 and participated in developing a competitive game for Apple Vision Pro.
Oh, there is a program like this. It is already April, but if there are companies, research institutions, or universities making content for XREAL and they are short-handed, I may not be a huge help, but I can assist. For what it is worth, I did win a prize in XREAL's AR JAM.
I feel like I saw somewhere that react-native-visionos cannot use expo, but I have been testing whether expo-gl can be used on its own. It does not seem straightforward, though.
This time, I want to write that when you decide to study Swift with Swift Playground, an old Mac can still be a viable option.
Now that I have managed to display an app for visionOS with React Native, I will next try displaying various components and check what they look like and whether they can be used.
