Undefined symbol: __llvm_profile_runtime when running unit/UI tests

If I try to run my unit/UI tests, after I installed the GoogleSignIn package with the swift package manager I get this error:

Command CompileSwiftSources failed with a nonzero exit code
`

Plus if I check the info panel in xCode I see the error: "Undefined symbol: __llvm_profile_runtime" until the GMTSessionFetcherCore target.

I am compiling with the flag '-fprofile-instr-generate'.

I also tried to enable code coverage for my target and for GTMSessionFetcherCore in my scheme, but I still get the error. Anybody has it? Any solution/workaround?

Start by reproducing the unit/UI test build after installing GoogleSignIn through Swift Package Manager with the reported -fprofile-instr-generate flag. Inspect the GTMSessionFetcherCore target and the CioMessagingPush compile step in the Xcode output. Done means the tests build without the __llvm_profile_runtime linker error and the required coverage configuration or workaround is identified.
