SonarCloud ran by github-actions doesn't generate code coverage for swift project

I have configured sonarcloud working with github-actions for my swift project and noticed that analysis indicates code coverage 0%.

My sonar-project.properties contains:

sonar.sources=CityRanks
sonar.exclusions=CityRanks/Shared/CityRanksAPI/**
sonar.tests=CityRanksTests

And here is a workflow:

name: SonarCloud Code Analysis

on:
  push:
    branches: [ master, develop ]
  pull_request:
    branches: [ master, develop ]

jobs:
  sonarcloud:
    runs-on: ubuntu-latest
    steps:
    - uses: actions/checkout@v2
      with:
        # Disabling shallow clone is recommended for improving relevancy of reporting
        fetch-depth: 0
    - name: SonarCloud Scan
      uses: SonarSource/sonarcloud-github-action@v1.3
      env:
        GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}
        SONAR_TOKEN: ${{ secrets.SONAR_TOKEN }}

I have found some workaround that depends on xcodebuild to generate code coverage, however it can run only on macos-latest machine which is not supported by sonarcloud github action for now. How can I resolve that problem?

Here is a log form scanner.
