How to setup devops pipeline for xamarin.forms ios app to build with ios 17 and xcode 15

Answer 1

I was able to build my xamarin.forms app successfully with xcode 15 (iOS 17) on azure hosted mac agent macOS-13 by making below changes to my yml.

1. I added below installation scripts at the very beginning in the job steps.

• task: Bash@3

    displayName: Install Xamarin
  
    inputs:
  
      targetType: 'inline'
  
      script: |
  
        brew install --cask xamarin-ios
  
        brew install --cask xamarin-android
  

1. Previously runNugetRestore was false in below task; due to which build was failing. I changed it to true and build was successful.
   • task: XamariniOS@2

       displayName: Build iOS Project
     
       inputs:
     
         solutionFile: $(System.DefaultWorkingDirectory)/pathtoslnfile.sln
     
         configuration: $(BuildConfiguration)
     
         clean: true
     
         packageApp: true
     
         buildForSimulator: false
     
         **runNugetRestore: true**
     

Hope this information will help others too; who are receiving errors while uploading IPA built from xamarin.forms app to testflight / App Store.

azure DevOps has MacOs build servers you can use. we are only 2 months from Xamarin support ending. but see: https://learn.microsoft.com/en-us/azure/devops/pipelines/ecosystems/xamarin?view=azure-devops&tabs=yaml
