Error in fail: A clang target must have at least one public header. target: GoogleSignIn

[marwanf1]

I am unable to add the GoogleSignIn spm.

spm_repositories(
    name = "swift_pkgs",
    dependencies = [
        spm_pkg(
            name = "GoogleSignIn",
            url = "https://github.com/google/GoogleSignIn-iOS.git",
            exact_version = "6.2.4",
            products = ["GoogleSignIn"],
        ),
    ],
)

Whenever I build, I get the following output:

Starting local Bazel server and connecting to it...

I'll try and look into this in the coming week.
