一、Xcode出现类似这样的报错Did not find header Environment/Public/GoogleUtilities/GULSecureCoding.h in framework GoogleUtilities说明GoogleUtilities的依赖没有正确导入。如果配制已经添加说明不同SDK对GoogleUtilities版本要求不同。Did not find header Environment/Public/GoogleUtilities/GULSecureCoding.h in framework GoogleUtilities (loaded from /Users/xxx/Library/Developer/Xcode/DerivedData/xxx-xxx/Index.noindex/Build/Products/Debug-iphoneos/GoogleUtilities)二、排查方法先将后面导入的新SDK配制暂时屏蔽清空pod依赖及相关缓存1、清空缓存rm -rf ~/Library/Developer/Xcode/DerivedData/rm -rf ~/Library/Caches/CocoaPods/pod deintegratepod cache clean --all rm Podfile.lock2、重新初使化旧依赖、工程pod install3、重新恢复新SDK配制再次初使化依赖pod install4、出现以下错误提示根据提示修正pod依赖配制的版本然后再执行步骤(二、1)。如果仍然不好解决最好使用Swift Package Manager导入解决依赖冲突问题
