macos - multiple device simulator warning

[salvatoreboemia]

Description

Hi I'm using this command to build

run: |
        echo "Building project manually..."
        xcodebuild -workspace MyApp.xcworkspace \
        -scheme MyApp \
        -destination "platform=iOS Simulator,name=iPhone 15 Pro,OS=18.1" \
        build | xcbeautify --renderer github-actions

But I got this warning

Why there are 2 simulator with same os and same model?

How I can remove this warning?

Thanks

Hey @salvatoreboemia!

Please, provide more info. 🙇

• When this happened for the first time? Which exact image version it was with?
• We need the full workflow code to test other steps if the source of the issue.

It seems to have always happened

it's only 1 warning but I would like to understand how to remove it

I opened the workflows from 1 month ago to today

Thanks @erik-bershel

Hmmmmm. 🤔 I'm starting to think the problem is somewhere in the workflow code. We have a duplicate check during the build. Of course, it might be buggy. We'll check the runner and come back later...

Hi @erik-bershel

Here are some main steps of my worflfow

runs-on: ${{ (matrix.language == 'swift' && 'macos-14-xlarge') }}

    - name: Set Xcode version
      run: |
        echo "Setting Xcode version..."
        sudo xcode-select -s /Applications/Xcode_15.4.app
        
    - name: Checkout repository
      uses: actions/checkout@v4


    - name: Initialize CodeQL
      uses: github/codeql-action/init@v3
     .....
     .....
      shell: bash
      run: |
        echo "Building project manually..."
        xcodebuild -workspace MyApp.xcworkspace \
        -scheme MyApp \
        -destination "platform=iOS Simulator,name=iPhone 15 Pro,OS=18.1" \
        build | xcbeautify --renderer github-actions

That's it

[erik-bershel]

Yeah, it doesn't look like any step creates additional simulators. It's strange - we'll look into it.
