Xcode 16 report 0% coverage using xcov

[rleojoseph]

I have been using XCode 14 and xcov to report coverage, it was working fine until we moved to Xcode 16. Gemfile has the following,

gem 'xcov', '1.8.1'
gem 'danger'
gem 'xcresult', '0.2.2'

And how I generate report,

 xcov(
        workspace: "NetworkPolling.xcworkspace",
        scheme: "Local",
        include_targets: "Network.app",
        include_test_targets: false,
        output_directory: outpul_directory,
        derived_data_path: "build/fastlane/derived_data",
        ignore_file_path: ignore_file_path,
        json_report: true,
        skip_slack: true,
      )

Output is

INFO [2024-10-07 08:48:23.70]: $ xcodebuild -showBuildSettings -workspace NetworkPolling.xcworkspace -scheme Local -derivedDataPath build/fastlane/derived_data 2>&1

If I try the same with legacy_support: true

then the output is like this,

We are seeing the same thing 😕 ... did you make any headway?

No @stephengilroy-grx . Still the same.
