一、问题现象：
有人会遇到 Xcode 升级到 16 后，新建应用然后使用 pod init命令会报错如下：
1，报错简介信息如下：
RuntimeError - `PBXGroup` attempted to initialize an object with unknown ISA `PBXFileSystemSynchronizedRootGroup` from attributes: `{"isa"=>"PBXFileSystemSynchronizedRootGroup", "exceptions"=>["3A838D4F2CA3ED7800EBAD00"], "explicitFileTypes"=>{}, "explicitFolders"=>[], "path"=>"ShareFileds", "sourceTree"=>"<group>"}`
If this ISA was generated by Xcode please file an issue: https://github.com/CocoaPods/Xcodeproj/issues/new
/opt/homebrew/Cellar/cocoapods/1.15.2_1/libexec/gems/xcodeproj-1.25.0/lib/x
2，报错详情信息如下：
[!] The version of CocoaPods used to generate the lockfile (1.16.2) is higher than the version of the current executable (1.15.2). Incompatibility issues may arise.

二、解决方案
第一步，打开工程，如下：
image.png
打开工程程序 - 选中左侧 - 所有蓝色文件夹📂 - 单个点击每个蓝色文件夹📂 - 右键选择 Convert to Group。选择Convert to Group完成后，文件夹会变成灰色，如上图，就是处理完成后的效果。
注：
①. 所有蓝色的文件夹📂，单个点击开都需要右键选择 Convert to Group。
②. 灰色文件夹，右键后就不会出现Convert to Group这个选项。
第二步：使用文本编辑器打开 xxxxx.xcodeproj文件操作【或者直接 去到项目根目录右击 xxxxx.xcodeproj文件 - 显示包内容】：
image.png
1、打开 xxxxx.xcodeproj 文件后，找到 project.pbxproj 文件
2、修改 project.pbxproj文件中以下内容：
objectVersion = 77;
改为：
objectVersion = 63; // 如果 63 不行，可以试试 56
image.png
然后使用关键词
PBXFileSystemSynchronizedRootGroup 全文搜索，删除如图中的代码段:【搜不出来，就无需处理】
image.png
保存修改，然后退出。
最后，你可以执行 pod init 以及pod install 测试下是否可以了。
