Using Unity to build this ios project, Added google signin SDK 4.0.1 Framework, I get error

I want google login in my app so i want to write unity plugin ,but i do not wanna use Play Games Unity plugin.

So I follow this tutorial (https://developers.google.com/identity/sign-in/ios/sdk/).

But after I have added the framework,I get error message.

My tool version

  1. Unity 5.6.0f3

  2. Xcode 8.3.1

  3. GoogleSign-In SDK 4.0.1

Xcode Builld error message

     ld: symbol(s) not found for architecture arm64
     clang: error: linker command failed with exit code 1 (use -v to see invocation)



When I googled about it , I found that it seems like something about arm64 support of Google Sign-In SDK.

I have set scripting backend on Unity to IL2CPP, and target architecture to Universa(both armv7 and arm64). Now I have no Idea to resolve these errors.
