右键项目.xcodeproject->显示包内容

image.png

打开project.pbxproj文件

搜索main
移除下面两行 minimizedProjectReferenceProxies，preferredProjectObjectVersion

minimizedProjectReferenceProxies = 1;
preferredProjectObjectVersion = 77;

修改 objectVersion = 77 改成 objectVersion = 56;

objectVersion = 56;

最后大退退出Xcode，重新启动之后就可以Pod成功了
