Getting the error "Module ApolloAPI was not compiled for testing" while compiling swift package in "Release" mode in apollo v1.7.0.

Summary

We have recently updated Apollo to version 1.7.0 in our project. We are not willing to update it further for now. We have encountered an issue that requires resolution. Our project setup involves adding ApolloTestSupport and ApolloAPI as targets in our Swift Package Manager (SPM) package along with other targets. This setup is necessary because we need to generate mock responses, and we are using mocks at various places in our code.

Here is a summary of our configuration:

We have added ApolloTestSupport and ApolloAPI as targets in our SPM package.
Inside this SPM, there are multiple targets, each with separate test mock folders generated using ApolloCodegen.
The issue arises when we try to compile the project. The error messages indicate that ApolloAPI was not compiled for testing.

Error Messages:

"Module 'ApolloAPI' was not compiled for testing"

Error Messages:

We seek guidance on how to resolve this error without removing ApolloTestSupport and ApolloAPI from our SPM targets since mock responses are a requirement for our project.
Any advice or suggestions would be highly appreciated.

Hi @divyansh0201 - this is being caused by the @testable attribute on the import of ApolloAPI in TestMock. As you're finding out, release builds do not enable testability by default. ApolloTestSupport was originally intended only for test cases but it's use has grown outside of that.

We switched to using an SPI import in PR #362 which was released in version 1.12.0. That should resolve the issue for you.

If you're not willing to move further past 1.7.0 you will need to fork from 1.7.0 and attempt to cherry-pick the PR but I'm not sure whether it's compatible.
