Issue Description

I upadated on GitHub my pipeline in order to use latest version of macOS and Xcode (13 and 14.3), but the slather scan failed (only with new macOS and Xcode version)

Command executed

scan(
      workspace: MyWorkspace,
      clean: true,
      device: "iPhone 8",
      # devices: ["iPhone 8", "iPad Air"],
      #output_files: "TEST-report.xml",
      scheme: MyTarget,
      code_coverage: true,
      skip_build: true,
      skip_testing: "ProjectNameTargetAppUITests",
      output_directory: "./DerivedData/test-output/scan",
      derived_data_path: "./DerivedData")
    
    slather(
      build_directory: "./DerivedData",
      scheme: MyTarget,
      workspace: ProjectWorkspace,
      proj: MyProject,
      output_directory: "./DerivedData/test-output/slatherOutput", 
      cobertura_xml: true,
      verbose: true,
      ignore: ["Pods/*", "fastlane/*", "build/*", "DerivedData/*"])      
  end

Complete output when running fastlane, including the stack trace and command used

Exit status of command 'slather coverage --cobertura-xml --build-directory ./DerivedData --output-directory ./DerivedData/test-output/slatherOutput --ignore Pods/\* --ignore fastlane/\* --ignore build/\* --ignore DerivedData/\* --verbose --scheme ProjectName --workspace ProjectName.xcworkspace ./ProjectName.xcodeproj' was 1 instead of 0.

	Are you sure your project is generating coverage? Make sure you enable code coverage in the Test section of your Xcode scheme.
	Did you specify your Xcode scheme? (--scheme or 'scheme' in .slather.yml)
	If you're using a workspace, did you specify it? (--workspace or 'workspace' in .slather.yml)
	If you use a different Xcode configuration, did you specify it? (--configuration or 'configuration' in .slather.yml)

Do you have any suggestions in order to fix this issue on GitHub and fastlane?

Thanks a lot

News on this issue on Xcode 14.3 and 14.3.1?

thanks

[salvatoreboemia]

News? I tried also on Xcode 15 and GitHub, but I got the same error

[salvatoreboemia]

With Xcode 14.2

Processing coverage file: /Users/runner/work/repo/repo/DerivedData/Build/ProfileData/

With Xcode 14.3.x or Xcode 15

No one on this issue? @ksuther @marklarr

thanks

[evelynloo]

@salvatoreboemia I am having the same error, do you manage to solve it?

Not able to manage... I removed slather step

If you will find a fix please update this post.

Thanks

Before you do anything with your CI configuration please make sure that Xcode generates coverage report locally, in our case we didn't have this file generated, so it's not a surprise that slather did fail.

Please try to check build logs or test report (depending on the Xcode version you're using) if you can find similar error to this one

error: no profile can be merged

If this is a case then solution described bellow might help you, I really hope it does.

We spent a lot of time debugging this problem, but none of the suggestions we found helped.

We tried to update our Podfile with these settings:

config.build_settings['CLANG_ENABLE_CODE_COVERAGE'] = 'NO'
config.build_settings['swiftc'] = '$(SRCROOT)/SWIFT_EXEC-no-coverage'

In our project Instrument Program Flow & Generate Legacy Test Coverage build settings were already set to NO

We also tried to change Mach-O type for our cocoa pods dependencies to **static library ** and many other things.

it appears that one of our dependencies was a binary (xcframework), most probably distributed via older version of the XCode, after updating it coverage was back.

I'm also facing this issue with Xcode 15.0 and 15.1. Would love to hear of a solution to this issue..

[jarrodlombardo-EventBase]

The solution is to make sure ALL of your upstream dependencies have been built with XCode 14.3 or newer. If ANY of your deps is not built with XCode 14.3 or newer, the .profraw file will be corrupt, so lldb-profdata will be unable to create a .prodata file for slather to parse.

[edward-sentongo]

I am currently facing the same issue. Any update on when this could get resolved?

[jarrodlombardo-EventBase]

@edward-sentongo Are you 100% sure it's not #541 (comment) ?

Does XCode show coverage % for all of the files you care about?

• If XCode is not showing the coverage, you have to fix that first and it's unrelated to Slather.
• If XCode is showing the coverage, but slather can't find it the files, you might have Failing to load coverage #545 or Different coverage percentage from XCode report #557

[edward-sentongo]

@jarrodlombardo-EventBase Xcode does show code coverage percentages for those files.
I'll look into other solutions you suggested. Thanks

[edward-sentongo]

We decided to build everything ourselves without using Slather.
That's how we got it working
