Coveralls reporting 0% code coverage with swift codebase?

[jackjpark]

I am running xcov and outputting the report to coveralls, travic ci generates the reports fine (I can see my coverage report in the CI console), yet coveralls reports 0% on every build.

I have run coverage on my default branch and several PR'd and there is a discrepancy between xcov output and coveralls stats

Any ideas here? i get a successfully sent message so am unsure how to proceed with debugging this issue

I've been experiencing this problem too.

My coveralls page shows 0% coverage for a Swift project that is generating coverage using xcov and running CI on travis.

https://coveralls.io/github/rakutentech/ios-remote-config https://coveralls.io/builds/25516715 https://travis-ci.com/rakutentech/ios-remote-config/builds/125836479#L2025 (shows real 90% coverage)

I plan to try https://github.com/nakiostudio/danger-xcov to skip coverage backends entirely and report directly on the PR.

@donnie-jp i tried that but the danger integration is different and doesnt send to coveralls, its just for code review it seems

Swift compilations via Xcode and Swift Package Manager use a new coverage format. Many of the existing Codecov tools deal with gcc. I was able to use xcrun llvm-cov export -format=lcov with the coveralls-lcov gem. I have working SPM example on csv-dialect-swift

The documentation on Swift language support needs to be updated since it currently references a deprecated tool that has been superseded by built-in tooling.

Thank u very much. It works!

I am using some 3rd libs, Do you know how to ignore SPM. I ignore the folders but looks like doesn't work

My coverage still decreased because the SPM is included.

@iRILLLL I have a vague recollection of that. llvm-cov has an -ignore-filename-regex option (llvm-cov export command documentation). It looks like I have an example of this in datapackage-swift, which has an SPM dependency, where I integrated coveralls with travisci
