问题描述
我新建了一个demo测试工程上，我只是执行简单的pod install，安装GcdSocket的pod库，terminal报错
RuntimeError - `PBXGroup` attempted to initialize an object with unknown ISA `PBXFileSystemSynchronizedRootGroup` from attributes: `{"isa" => "PBXFileSystemSynchronizedRootGroup", "exceptions" => ["B6DA7F782DD4A25000D9234F"], "path" => "Demo", "sourceTree" => "<group>"}`
If this ISA was generated by Xcode please file an issue: https://github.com/CocoaPods/Xcodeproj/issues/new

🐞解决方案
步骤 1：在 Xcode 中右键单击项目文件夹并转换为组
步骤 2：右键单击projectname.xcodeproj文件并选择显示包内容，
您可以看到文件project.pbxproj并使用文本编辑器打开
删除此文件中的以下行
minimaledProjectReferenceProxies = 1;
preferredProjectObjectVersion = 77;
还将以下版本
objectVersion = 77; 更新为 objectVersion = 56;
现在你可以使用你的项目进行 pod init 和 install
之后需要把version改回去 objectVersion = 77，不然workspece打开之后不能编辑之前的project.pbxproj
