一、問題現象：
有人會遇到 Xcode 升級到 16 后，新建應用然后使用 pod init命令會報錯如下：
1，報錯簡介信息如下：
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，報錯詳情信息如下：
[!] 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、解決方案
第一步，打開工程，如下：
image.png
打開工程程序 - 選中左側 - 所有藍色文件夾?? - 單個點擊每個藍色文件夾?? - 右鍵選擇 Convert to Group。選擇Convert to Group完成后，文件夾會變成灰色，如上圖，就是處理完成后的效果。
注：
①. 所有藍色的文件夾??，單個點擊開都需要右鍵選擇 Convert to Group。
②. 灰色文件夾，右鍵后就不會出現Convert to Group這個選項。
第二步：使用文本編輯器打開 xxxxx.xcodeproj文件操作【或者直接 去到項目根目錄右擊 xxxxx.xcodeproj文件 - 顯示包內容】：
image.png
1、打開 xxxxx.xcodeproj 文件后，找到 project.pbxproj 文件
刪除以下兩行：
minimizedProjectReferenceProxies = 1;
preferredProjectObjectVersion = 77;
2、修改 project.pbxproj文件中以下內容：
objectVersion = 77;
改為：
objectVersion = 56; // 如果 63 不行，可以試試 56
保存修改，然后退出。
最后，你可以執行 pod init 以及pod install 測試下是否可以了。
