### Error

```
RuntimeError - [Xcodeproj] Unknown object version (56).
/Users/zst01/.rvm/rubies/ruby-3.0.0/lib/ruby/gems/3.0.0/gems/xcodeproj-1.21.0/lib/xcodeproj/project.rb:228:in `initialize_from_file'

........

提示： Unknown object version (56) --未知对象版本（56）

解决：如何修改compatibilityVersion呢？可以通过 Project Format，可以暂时将Project Format：

 Xcode 14.0-compatible改为Xcode 13.0-compatible

如图：

 原因：

是版本不匹配导致的，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
