Building with 'dotnet publish' in ADO Pipeline

[vikern22]

Description

Hi!

Not sure if this is the correct place to post, but;

I'm having some issues building our MAUI-app for iOS in Azure Devops Pipelines. While building for Android seems ok, the iOS build always gets stuck on:

Optimizing assemblies for size may change the behavior of the app. Be sure to test after publishing. See: https://aka.ms/dotnet-illink Optimizing assemblies for size. This process might take a while.

It builds fine with the same build config in VS for Mac and in terminal on the same Mac - a Mac that seemingly has the same versions as the agent in ADO.

• macOS-13 agent
• Xcode 14.3
• .NET SDK 7.0.306
• MAUI 7.0.92

I've tried using the macOS-12 agent with Xcode 14.2 as well - same result, only with a warning that Xcode 14.3 is recommended.

Steps to Reproduce

1. Run dotnet publish -f net7.0-ios -c ReleaseMaui -p:RunTimeIdentifier=ios-arm64 -p:ApplicationVersion=$(VersionOrdinal) -p:ApplicationDisplayVersion=$(VersionString) -p:CodesignKey=$(CodeSignKey) -p:CodesignProvision=${{ parameters.provisioningId }} in ADO-pipeline
2. Get stuck at optimizing step
3. ADO pipeline gives up and stops the job after 6+ hours

Still struggling with this issue - but don't really know how to approach it. Does anyone have success with building iOS in ADO-pipelines? Is it possible to get more build output, to see what task it actually gets stuck on? Is there any more logical place to post about this?

We have .NET MAUI iOS and Android release builds successfully running on ADO. Could you try changing the iOS release config to LLVM off? That seems to ring a bell with me...

Thanks - testing now!

Still stuck with <EnableLLVM>false</EnableLLVM> :(

Just tested with a completely fresh "File -> new"-project, same issue occurs in ADO pipelines

I'll give it a shot. Thanks!

No luck :/

Recreate provisioning profile and cert? Without logging in and taking a look, I doubt I can be much help now. I have just run a release build on macos13 and it is working for us.

Seemed to be an issue with the certificate indeed. We tested building on a Mac that just had the certificate installed - and on the optimizing step a password prompt appeared!

We then discovered that we were trying to install the certificate to a specific keychain on the agent, and changed it to use the default, and now it runs to completion.
