Undefined symbols for architecture arm64
Raw
undefined_symbols.md

在Swift中使用Google Nearby API的时候，遇到了以下错误

Undefined symbols for architecture arm64:
"OBJC_CLASS$_GNSMessageManager", referenced from:
objc-class-ref in TBGNSMessager.o
"OBJC_CLASS$_GNSMessage", referenced from:
objc-class-ref in TBGNSMessager.o

尝试在Other Linker Flags中添加-ObjC无果

最后找过这个解决方案，在Other Linker Flags中添加$(inherited)

原文是这样说的： If your Architectures and Valid Architectures are all right, you may check whether you have added $(inherited) , which will add linker flags generated in pods, to Other Linker Flags as below: enter image description here

关于$(inherited)的用法可以看SwiftGG的文章
