解决步骤 #

• 更新CocoaPods及依赖库
  旧版本的CocoaPods（1.11.3）和xcodeproj（1.21.0）不兼容Xcode 14+的项目对象版本56，执行以下命令更新：

  sudo gem install cocoapods
  sudo gem install xcodeproj
  

• 确认Xcode版本
  项目对象版本56对应Xcode 14及以上版本，确保使用的Xcode是匹配的稳定版，若版本过低需升级Xcode。
• 清理CocoaPods缓存（可选）
  若更新后仍报错，清理缓存后重试：

  pod cache clean --all
  

  之后重新进入项目目录执行pod init。
• 验证Rosetta设置
  重启终端，确保“Open Using Rosetta”设置已生效，再执行命令。
