How can we configure CI for the iOS app with App Extensions

问题

I have tried multiple things in Azure DevOps (VSTS) to create CI for the iOS app but turns out that Azure DevOps doesn't support the apps that have App extensions. Is it really the case?

I'm using the OneSignal Notification Service Extension in our project which is dependent on the main target. So, when Xcode task tries to sign the app an error occurs related to the build identifiers as the Xcode main target has a different build identifier than OneSignalNotificationServiceExtension's build identifier.

❌ error: Provisioning profile "MainTargetName" has app ID "com.xyz.-", which does not match the bundle ID "com.xyz.-.OneSignalNotificationServiceExtension". (in target 'OneSignalNotificationServiceExtension' from project 'ProjectName')

I'm using an apple certificate task to install the certificates on the Microsoft hosted agent and similarly using the provisioning profile task to install the provisioning profiles. It looks like the Xcode task has a limitation that it cannot get multiple provisioning profiles so it can cater to those iOS apps with App Extension.

- task: InstallAppleCertificate@2
  displayName: 'Install Certificates'
  inputs:
    certSecureFile: '3Certificates.p12'
    certPwd: '$(P12Password)'
    keychain: 'temp'


- task: InstallAppleProvisioningProfile@1
  displayName: 'Install MainTarget provisioning profile'
  inputs:
    provisioningProfileLocation: 'secureFiles'
    provProfileSecureFile: 'MainTarget.mobileprovision'

- task: InstallAppleProvisioningProfile@1
  displayName: 'Install OneSignal provisioning profile'
  inputs:
    provisioningProfileLocation: 'secureFiles'
    provProfileSecureFile: 'OneSignal.mobileprovision'

- task: CmdLine@2
  displayName: 'CocoaPods install'
  inputs:
    script: |
      cd $(Build.SourcesDirectory)
      echo "Pod installation"
      pod install
- task: Xcode@5
  displayName: 'Xcode Build'
  inputs:
    actions: 'build'
    xcWorkspacePath: 'CICD.xcworkspace'
    scheme: 'CICD'
    xcodeVersion: 'specifyPath'
    xcodeDeveloperDir: '/Applications/Xcode_11.2.1.app'
    packageApp: true
    exportOptions: 'plist'
    exportOptionsPlist: 'CICD/Info.plist'
    signingOption: 'manual'
    signingIdentity: '$(MY_CERTIFICATE_SIGN_IDENTITY)'
    provisioningProfileUuid: '$(MainTarget_ProfileUUID)'
    provisioningProfileName: '$(MainTarget_ProfileName)'

Let me know if I'm missing something here.

Unfortunately, there is not a straight forward way for the iOS application with App extension in Azure.

To make it work you'll have to do a couple of changes in the project that are recommended on this link.
Afterward, you'll be able to build and archive the application using xcodebuild Docs. because you'll have a variable pointing to each provisioning profile.
On your MAC try xocdebuild command in the terminal and note down the full commands to achieve a specific file.
Use CmdLine@2 task in the pipeline with these commands to build, archive & export your IPA.

Note: I have posted a Gist covering the pipeline for such an iOS application.
