https://stackoverflow.com/questions/68081067/spm-cache-not-working-on-github-actions-any-ideas suggests that is true if you are using swift package directly, but not if the resolution is being done by xcodebuild, as is being done here

OK so we specify cloned_source_packages_path in scan/run_tests and replace path: .build with the path specified in run_tests' cloned_source_packages_path parameter.

I looks like specifying derived_data_path also works. Do you have strong opinions on which is better?

I lean toward the cloned source option rather than the entire derived data. It seems more precisely targeted to what we want.

And it seems CI does not take long at all to grab the spm managed packages currently.

🤞 the direct cache would be faster. It probably would be more efficient in any case.
