xcode 10.1 Undefined symbols for architecture arm64

问题

I already gone so many SO threads with similar issue but none of them seems to resolve my error.

In our project we have multiple "TARGETS". Only one of the target - the very first target created ever - is archiving properly. When I try to archive other target we encounter this error

Undefined symbols for architecture arm64:
  "_OBJC_CLASS_$_DynamicEventData", referenced from:
      objc-class-ref in DataManager.o
      objc-class-ref in DataReader.o
  "_OBJC_CLASS_$_DynamicDataService", referenced from:
      objc-class-ref in DataManager.o
  "_OBJC_CLASS_$_DynamicDataConfig", referenced from:
      objc-class-ref in DataManager.o
ld: symbol(s) not found for architecture arm64
clang: error: linker command failed with exit code 1 (use -v to see invocation)

I did compare the Build Setting of the working target to the other targets but all of them are equal. I checked the header files and they exists in our project directory. I tried to manually add the header files' path to Header Search Paths but same result still getting the error.

Any idea? I really need to resolve this to export an ipa file.

Thanks!

回答1:

I scan manually check the Build Phases > Link Binary With Libraries of the working target vs the defected targets. I found a one framework/library that was only added to the working target the said framework isn't manage by pod that may explain why the other target doesn't have it. I think it was added manually in the project.

I add the said framework to all targets and now I can build without the said error.

Thanks!
