how to select xcode version in fastlane when using github actions

Question

I am using fastlane in github actions to build my project, this is my github actions script:

name: Cruise-CI

on:
  push:
    branches: [ main ]

jobs:
  build:
    runs-on: macos-latest
    steps:
    - uses: actions/checkout@v2
    - uses: actions/setup-java@v1
      with:
        java-version: '12.x'
    - uses: subosito/flutter-action@v1
      with:
        flutter-version: '1.22.5'
    - name: Select Xcode version
      run: sudo xcode-select -s '/Applications/Xcode_12.1.app/Contents/Developer'
    - name: Bundle install
      run: cd ./ios && bundle install && bundle update fastlane
    - name: Install tools
      run: |
       flutter precache
       flutter pub get
       cd ./ios && pod repo update && pod install
    #- run: flutter pub get
    #- run: flutter build apk
    #- run: flutter build ios --release --no-codesign
    - name: Setup SSH Keys and known_hosts for fastlane match
      run: |
        SSH_PATH="$HOME/.ssh"
        mkdir -p "$SSH_PATH"
        touch "$SSH_PATH/known_hosts"
        echo "$PRIVATE_KEY" > "$SSH_PATH/id_rsa"
        chmod 700 "$SSH_PATH"
        ssh-keyscan github.com >> ~/.ssh/known_hosts
        chmod 600 "$SSH_PATH/known_hosts"
        chmod 600 "$SSH_PATH/id_rsa"
        eval $(ssh-agent)
        ssh-add "$SSH_PATH/id_rsa"
      env:
        PRIVATE_KEY: ${{ secrets.SSH_PRIVATE_KEY }}
    - name: Deploy to TestFlight/PGY
      run: |
        cd ./ios && bundle exec fastlane beta
      env:
        APPLE_ID: ${{ secrets.APPLE_ID }}
        GIT_URL: ${{ secrets.GIT_URL }}
        PGY_USER_KEY: ${{ secrets.PGY_USER_KEY }}
        PGY_API_KEY: ${{ secrets.PGY_API_KEY }}
        TEAM_ID: ${{ secrets.TEAM_ID }}
        ITC_TEAM_ID: ${{ secrets.ITC_TEAM_ID }}
        FASTLANE_USER: ${{ secrets.FASTLANE_USER }}
        FASTLANE_PASSWORD: ${{ secrets.FASTLANE_PASSWORD }}
        FASTLANE_APPLE_APPLICATION_SPECIFIC_PASSWORD: ${{ secrets.FASTLANE_APPLE_APPLICATION_SPECIFIC_PASSWORD }}
        FASTLANE_SESSION: ${{ secrets.FASTLANE_SESSION }}
        MATCH_PASSWORD: ${{ secrets.MATCH_PASSWORD }}
        MATCH_KEYCHAIN_NAME: ${{ secrets.MATCH_KEYCHAIN_NAME }}
        MATCH_KEYCHAIN_PASSWORD: ${{ secrets.MATCH_KEYCHAIN_PASSWORD }}
        DELIVER_ITMSTRANSPORTER_ADDITIONAL_UPLOAD_PARAMETERS: ${{ secrets.DELIVER_ITMSTRANSPORTER_ADDITIONAL_UPLOAD_PARAMETERS }}

and this is my Fastfile script:

update_fastlane

default_platform(:ios)

platform :ios do
  desc "Push a new beta build to pgy"
  before_all do
    ENV["CACHE_GIT_URL"] = ENV["GIT_URL"]
  end

  lane :beta do
    xcode_select('/Applications/Xcode_12.1.app')
    if is_ci
      create_keychain(
        name: ENV['MATCH_KEYCHAIN_NAME'],
        password: ENV["MATCH_KEYCHAIN_PASSWORD"],
        default_keychain: true,
        unlock: true,
        timeout: 3600,
        lock_when_sleeps: false
      )
    end

    match(
      app_identifier: ENV["APP_IDENTIFIER"],
      git_url: ENV["GIT_URL"],
      type: "adhoc",
      readonly: is_ci,
      keychain_name: ENV['MATCH_KEYCHAIN_NAME'],
      keychain_password: ENV["MATCH_KEYCHAIN_PASSWORD"]
    )

    build_app(
        workspace: "Runner.xcworkspace",
        scheme: "Runner",
        export_method: "ad-hoc"
    )

    pgyer(
        api_key: ENV['PGY_API_KEY'],
        user_key: ENV['PGY_USER_KEY']
    )
  end
end

but when runs in github actions shows this error :

** ARCHIVE FAILED **

[04:51:35]: Error building the application - see the log above

I have already tried to specify the version of xcode in fastlane file like this:

xcode_select('/Applications/Xcode_12.1.app')

but still not work, what should I do to fix this? I also tried to change the xcode version to 12.3 follow this doc like this:

xcode_select('/Applications/Xcode_12.3.app')

still now work.

Answer 1

You are running on the latest MacOS image (which, at time of writing, is macos-10.15 with Xcode 12.4.0.0.1.1610135815 —see installed tools ):

 jobs:
  build:
    runs-on: macos-latest

But you are trying to select a specific version of Xcode to use:

- name: Select Xcode version
      run: sudo xcode-select -s '/Applications/Xcode_12.1.app/Contents/Developer'

The latest MacOS version (and the installed Xcode version) are liable to change if you use the -latest suffix when specifying the runs-on image.

Ensure that your MacOS and Xcode versions are compatible or just remove the Select Xcode version step entirely.
