Is it possible to use it without project configuration (xcodeproj)?

I'm trying to generate a coverage report for a Swift Package.

I'm currently generating the report with a command like this:

xcodebuild test \
    -scheme BokenEngine \
    -destination "platform=iOS Simulator,name=iPhone 11" \
    -enableCodeCoverage=YES \
    -derivedDataPath=.DeriveData
ld -r \
    -o ./CombinedObject.o .DeriveData/Build/Intermediates.noindex/BokenEngine.build/Debug-iphonesimulator/BokenEngine.build/Objects-normal/arm64/*.o
xcrun llvm-cov report \
    --format=text \
    --instr-profile=".DeriveData/Build/ProfileData/860AB2C1-6615-42E7-93A8-9067DF75E7BA/Coverage.profdata" \
    --object="./CombinedObject.o"

I tried to use Slather but I get this error:

% slather coverage -s --scheme BokenEngine --build-directory ".DerivedData" --binary-file "./CombinedObject.o"

Would it be possible to use Slather without any project configuration?

By the way, I was looking for a GitHub Action to run Slather but I have not found it.

I think this is a duplicate of #466. I'd love to see support for this added, myself.
