Could not find test host

[ethanmacanas]

I'm attempting to use Github Actions with Macos and xcodebuild to automate our CI/CD testing for a test app. The test app contains unit tests that have dependencies installed and managed through cocoapods. I've setup the CI/CD pipeline to generate the xcodeproj and xcworkspace through xcodegen. Then install the relevant pods and execute xcodebuild clean, build-for-testing, and test-without-building commands. However, I am not able to execute the commands in github actions. I receive the error on the build-for-testing command.
xcodebuild: error: Failed to build workspace REDACTED with scheme REDACTED. Reason: Could not find test host for REDACTED: TEST_HOST evaluates to "/Users/runner/work/REDACTED/REDACTED/build/Build/Products/Debug-iphonesimulator/REDACTED.app/REDACTED" make: *** [build-xcodeproj-artifactory] Error 70

Looks like it was an issue with https://github.com/nightstory/setup-xcodegen. Manually installing xcodegen with brew resolved the problem
