[iOS] MAUI project won't build with the 8.0.0-rc.2.9530 version on Azure Pipeline

[Yokaichan]

Description

The Azure Pipeline, set to use the 8.0.x version, install the Microsoft.Maui.Sdk version 8.0.0-rc.2.9530 and the microsoft.net.sdk.ios version 17.0.8477-net8-rc2.2.
But with those versions, the project won't build anymore.

I already tried to change the csproj with:

• <PublishTrimmed>false</PublishTrimmed>
• to change the SupportedOSPlatformVersion

Steps to Reproduce

No response

Link to public reproduction project repository

No response

Version with bug

Unknown/Other

Is this a regression from previous behavior?

Yes, this used to work in .NET MAUI

Last version that worked well

8.0.0-rc.2.9511

Affected platforms

iOS

Affected platform versions

microsoft.net.sdk.ios version 17.0.8477-net8-rc2.2.

Did you find any workaround?

No

I think you need to install/select Xcode 15.

Try running this as part of the setup:

sudo xcode-select -s /Applications/Xcode_15.0.1.app

Thank you for your response but I'm not very familiar with Azure Pipeline and when I try to add the sudo code, the error "invalid developer directory" appears.

Edited: I added the yaml file which describe the pipeline
pipeline.txt

Hi @Yokaichan,

Check the use-custom-xcode-template.txt template. You can use like this in your pipelines (or you can just copy the ask inside of it).

- template: use-custom-xcode-template.yml
- task: UseDotNet@2
  displayName: 'Use .NET Core sdk 8.0.0'
  inputs:
    version: 8.0.x
    includePreviewVersions: true

Also you will need to run the pipeline on macos13 by setting

pool:
  vmImage: macOS-13

[jfversluis]

Let us know if that worked!

I was having the same issue and thanks to the responses here I was able to resolve it.

However, at first, I only added the Xcode script as I was already targeting macOS-latest so I thought I didn't need to specify macOS-13 but it turns out I did!

[Yokaichan]

Thank you very much !

based on your response I added those two lines before my workload install script:

sudo xcode-select -s /Applications/Xcode_15.0.1.app
xcodebuild -version

And I set the agent specification to maco-13 and it works like a charm.

I didn't try to set both xcode version and macos-13 (I thought that latest means 13 in this case).

[daryltt]

I can confirm that I had the same issue with github actions. I had to do two things to resolve:

• Change runs-on: macos-latest to runs-on: macos-13
• Add a step to use the latest xcode:
  - uses: maxim-lobanov/setup-xcode@v1
  with:
  xcode-version: latest

@GeorgeDarakchiev Thank you for the script idea - it did fixed my pipeline that was "hoping" that the algorithm would pick up the latest and greatest as the instructions in my pipeline. I want to double-check with you great people who are smarter than myself in the area of azure deployment architecture: is my understanding correct that we need the above solution only for the time being until Microsoft adjusts it's algorithm to actually use the latest xcode by default, right? Or it is always necessary to manually instruct the pipeline about the version of xcode to use???

Heu @MichaelShapiro ,

Choosing the exact version of Xcode is needed until the desired version is set as default. You can check what is the default version of the Xcode in the https://github.com/actions/runner-images repo.

Thank you very much for the info!

Are there any suggestions for Azure DevOps? The discussion here revolves around github actions, but the same problem exists with Microsoft hosted agents on Azure DevOps.

[stevedcc]

It turns out "sudo xcode-select -s /Applications/Xcode_15.0.1.app" is sufficient for AzureDevOps: the "Recent updates" documentation at https://learn.microsoft.com/en-us/azure/devops/pipelines/agents/hosted?view=azure-devops&tabs=yaml does not list xcode 15 as installed, but it the detailed list for macos-13 does show it as present.
