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。
