解决办法1：

在命令行复制粘贴一下命令：

 gem install cocoapods --pre --user    

按下Enter键之后，更新cocoapods成功之后，再次pod init 就成功啦。

解决办法2：

查看错误日志发现有一条很重要的信息，应该是版本不匹配导致的，那应该和升级Xcode 14有关系。

in `initialize_from_file': [Xcodeproj] Unknown object version (56). (RuntimeError)

但是官方还没有给出解决方案。应该后续会有兼容的cocoapods 新版本。
通过与老项目对比发现是compatibilityVersion Xcode兼容版本不一致，那么我们就可以将这个版本修改到低版本试试呢。
如何修改compatibilityVersion呢？可以通过 Project Format，可以暂时将Project Format 改为Xcode 13.0-compatible
具体如下图：

只需要在工程里面把这个修改到14以下就行了。再次去pod init就成功了。
