我可以编写一个 Android 应用程序，然后使用 react-native 构建一个 IOS 应用程序吗？

我开始学习 react-native 并且在设置环境时遇到了一些问题，我对此有一些疑问：

首先当我写：

npx react-native init new_app

我收到一个错误，该错误说尝试：

cd ./new_app/ios && pod install

然后我收到以下错误：

我知道我需要安装 Xcode，但由于某些原因我现在不想安装，那么我可以做些什么来让它在没有安装 Xcode 的情况下工作？

第二个问题，如何首先为 Android 初始化一个 react-native 应用程序？如果有办法做到这一点，当我想构建 IOS 应用程序时，我会遇到一些麻烦还是只需要 Xcode 然后为 IOS 构建相同的 android 代码？还是应该为 IOS 和 Android 准备好环境然后开始处理您的应用程序？
