Setting up Code Coverage Report for Swift iOS application

  • Repos in Azure Repos
  • CI system used Azure DevOps
  • Languages of the repository - iOS apps using Swift

SonarQube used to work before Xcode 11, now Xcode 13 is being used and Sonar reports are not getting generated.

I am looking for a well guided article for best practices in iOS code coverage setup.
Xcode Test is passed with below args and is generating xcresult file.
-derivedDataPath Build/ -enableCodeCoverage YES -resultBundlePath Build/Logs/Test/Test/

Previous setup utilized a bash to process the xcresult and generate sonar coverage file. This is failing.
Internet search and solutions dont seem to be working.

Since it is running on a hosted build agent, files cant be retained for debug it seems.

Has anyone found a workable solution for iOS apps with a similar approach.

Hello,

what is this error logs you have posted? Is it from running bash script? which script exactly?

Do you have similar line among the logs?

xccov-to-sonarqube-generic.sh: line 68: jq: command not found

If so, you should install jq on the machine where you generate the coverage report.

Hi Elena, thanks for responding.
This is the output of the file you have mentioned.
The output is from an Azure DevOps hosted MacOS agent that already has JQ installed as per their documentation(also no similar line for jq not being present).

I do see there is a metadata.db in a different folder, not sure if that is relevant to this script.
