React Native 上开发 VisionOS App 初步尝试

 npx @callstack/react-native-visionos@latest init app_name 

cd visionos
bundle install
bundle exec pod install

yarn start # 这个不要忽略，这是 yarn visionos 执行起来的基础
yarn visionos

      const top10Ids = ids.slice(0, 10);

      const storyPromises = top10Ids.map(id => fetch(`https://hacker-news.firebaseio.com/v0/item/${id}.json`).then(res => res.json()));
      const stories = await Promise.all(storyPromises);

      setStories(stories);
    };

    fetchStories();
