Unable to use into generated ***ClientProtocol into Test Target

adriantabirta commented 2 years ago

Describe the bug

Got: Missing required module 'CNIOAtomics'

Hard: MacBook M1 Soft: latest Xcode version on Ventura, swift version 5.7.1, grpc-swift(1.10.0) in SPM package,

SPM package here

To reproduce

Steps to reproduce the bug you've found:

Create simple Xcode project and add package as dependency
Try to use GeneratedServiceClientProtocol to create RideServiceClientProtocolMock into test target
Got error/s

Expected behaviour

I want to use generated client protocol to create mock classes for testing.

Additional information

Have tried to use @_exported import ... in SPM package - same error,
Have tried to add grpc-swift as dependency into Xcode project alongside with created SPM package - error, duplicated code

Added created package to Link binary with Libraries in Test Target - give me errors like:

Undefined symbols for architecture arm64:
"_$s19TaxifyClientSwiftUI20RideRemoteDataSourceMp", referenced from:
  _symbolic ______pSg 19TaxifyClientSwiftUI20RideRemoteDataSourceP in RealRideRemoteDataSourceTests.o

Is there a way to forward correctly dependencies like grpc-swift -> my SPM package -> Xcode (especially test target)? Notice: Mocking is working on application target, am I doing something wrong?

This seems like an Xcode issue: does this build correctly otherwise?

otherwise how?

Only solution I found it is to add grpc-swift as package dep to Xcode project test target. So basically I import 2 times and got this in terminal when I run tests:

objc[49542]: Class _TtC6NIOTLS37ApplicationProtocolNegotiationHandler is implemented in both

 One of the two will be used. Which one is undefined.

Yeah, I think this will require filing a report using Feedback Assistant or asking for help on the Apple Developer Forums. This issue appears to be with Xcode, not with grpc-swift.

grpc / grpc-swift
