Could someone point me to a working Github Action ...

Could someone point me to a working Github Action for building (or testing) a KMM iOS app with cocoapods integration? Somehow the shared pod doesn’t get linked properly and I’m all out of ideas.
My non-working best shot:
Copy code
Test_iOS:
    runs-on: macos-11
    steps:
      - uses: actions/checkout@v2
      - uses: dorny/paths-filter@v2
        name: Setup file extension filters
        id: changes
        with:
          filters: |
            swift:
              - '**.swift'
            shared:
              - '**.kt'
              - 'shared/'
      - if: steps.changes.outputs.shared == 'true' || steps.changes.outputs.swift == 'true'
        name: Setup JVM
        uses: actions/setup-java@v2
        with:
          distribution: 'temurin'
          java-version: 11
      - if: steps.changes.outputs.shared == 'true' || steps.changes.outputs.swift == 'true'
        uses: xavierLowmiller/xcodegen-action@1.1.2
        name: Run xcodegen
        with:
          spec: ios/project.yml
          quiet: false
          version: '2.25.0'
      - if: steps.changes.outputs.shared == 'true' || steps.changes.outputs.swift == 'true'
        name: Install Dependencies
        run: |
          cd ios
          pod install
        shell: bash
      - if: steps.changes.outputs.shared == 'true' || steps.changes.outputs.swift == 'true'
        name: Run xctest
        run: >-
          xcodebuild test -workspace ios/Spenderino.xcworkspace -scheme Spenderino -destination 'platform=iOS Simulator,name=iPhone 13,OS=15.0'

try this, afaik you should really only need the two commands below (don't include any pod install steps). Ps as a tip for finding these workflows search open source repos using sourcegraph https://sourcegraph.com/search) https://github.com/icerockdev/moko-resources/blob/master/.github/workflows/compilation-check.yml#L27 https://github.com/icerockdev/moko-resources/blob/master/.github/workflows/compilation-check.yml#L36

They do pod install as well though? Thanks for the tip btw.
I’m trying building the kotlin part before pod install now.
e
that's true... maybe there's something about at what stage you run the pod install, when I tried including the pod install on bitrise it didn't work.
that is, I tried to follow this recipe, but it didn't work, but I got it working without the pod install step. https://blog.bitrise.io/post/getting-started-with-kotlin-multiplatform-mobile-kmm

Well, at least it runs now. • install java • run gradle iosX64Test • pod install • run xctest (expecting a fail, therefore continuing on error) • pod install • run xctest I have no idea why I need to build the iOS part once before pod install works, but that’s somehow how it went. Thanks @Eamon Keane for trying to help 🙂

ok cool, thanks for the feedback, I'll try that too!

The pod support has always been kind of funky. On a completely new build, you need to run 
pod install
multiple times, as you’ve found. The actual thing is you run 
pod install
, which sets up the Xcode run script, when that first xctest run runs a gradle command that fails, but does init something. Running 
pod install
agian then copies a shell framework. After that, the Xcode run script gradle succeeds. Not sure if/how that gets resolved, but it’s been a thing for a while. Obviously worse on CI.

Thanks Kevin, I see it now, a 4 year old Xcode issue! In 
icerockdev
repo, he has a workaround by adding a preinstall line into the Podfile.
Copy code
install! 'cocoapods', :disable_input_output_paths => true
https://github.com/CocoaPods/CocoaPods/issues/8073 https://github.com/icerockdev/moko-resources/blob/master/sample/ios-app/Podfile#L11 scratch that, it actually failed, but maybe there's something in the way he has it setup.
The double cocoapods install works on bitrise too 🙃, thankfully doesn't delay build. Here's the script for anyone who stumbles across this in the future.

hey @Eamon Keane i tried out your suggestion, but i think it hangs during the Xcode build for simulator step.
