error MT0180: This version of Microsoft.iOS requires the iOS 16.1 SDK (shipped with Xcode 14.1)

[faceoffers28]

Description

I'm having major issues after the latest .Net Maui updates. My iOS app will no longer build.

Here is a link to the initial GitHub issue I created. microsoft/azure-pipelines-tasks#17477

After forcing ASP.net to use 7.0.100 and Xamarin to use xamarin-sdk.sh 17_4_0_301, I'm still getting the error.

I even tried to force XCode to version 14.1 using the CmdLine@2 Task.

- task: CmdLine@2
  displayName: 'Set XCode Version'
  inputs:
    script: |      
      sudo xcode-select -s /Applications/Xcode_14.1.app

Does anyone know where this error is coming from? Is this coming from the Maui install? If so, how do I fix this? As-is, I can no longer build my iOS app.

Image version and build link

Current image version: '20221204.1'

Is it regression?

Current image version: '20221204.1'

Expected behavior

I would expect for the app to build.

Actual behavior

The app no longer builds.

Repro steps

Try to build a .Net Maui iOS app targeting iOS 16 with the Microsoft Visual Studio Enterprise 2022 (64-bit) - Current
Version 17.4.3 SDKs using the macos-12 image.

[faceoffers28]

I think the problem lies with the latest version of .Net Maui.

I can see that the Maui install Task is installing this version of microsoft.net.sdk.ios.

Installing workload manifest microsoft.net.sdk.ios version 16.1.1481

This is the version used in my last successful build.

Installing workload manifest microsoft.net.sdk.ios version 16.0.1478

I'm facing the same issue. Azure Dev Ops pipeline builds are failing that were working earlier this week due to this same error. So I think this is a .Net Maui issue.

[igorboskovic3]

Thank you @faceoffers28 , we will check it, can you provide minimal repro steps?

[gabsamples6]

Hi @igorboskovic3
Since upgrading to latest version of visual studio any maui app launched as iOS we get an error

1. Launch Visual studio (Microsoft Visual Studio Enterprise 2022 (64-bit) - Current Version 17.4.3)
2. Create a Maui App
3. Pair to a mac (optional)
4. Build the app

[berhir]

@gabsamples6 I don't want to ask the obvious question, but you didn't say what XCode version you are using. Did you update to XCode 14.1?

Anyway, this issue is about building on an Azure DevOps hosted agent.

[berhir]

@igorboskovic3 the iOS build with the latest MAUI version doesn't work for us too.
This is how I select the correct XCode version:

  - task: Bash@3
    displayName: Select xcode version
    inputs:
      targetType: 'inline'
      script: |
        sudo xcode-select -s "/Applications/Xcode_14.1.app"

The build works fine, but when the "Optimizing assemblies" stuff starts, I get this warning:
ILLINK : warning MT0079: The recommended Xcode version for Microsoft.iOS 16.1.1481 is Xcode 14.1 or later. The current Xcode version (found in /Applications/Xcode_14.0.1.app/Contents/Developer) is 14.0.1. [/Users/runner/work/1/s/src/MyProj.csproj::TargetFramework=net7.0-ios]

After some time, it fails with this error:

xcodebuild: error: SDK "/Applications/Xcode_14.1.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX.sdk" cannot be located.
xcrun: error: sh -c '/Applications/Xcode_14.1.app/Contents/Developer/usr/bin/xcodebuild -sdk /Applications/Xcode_14.1.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX.sdk -find dsymutil 2> /dev/null' failed with exit code 16384: (null) (errno=Invalid argument)
xcrun: error: unable to find utility "dsymutil", not a developer tool or in PATH

In the error message it looks like it's using XCode 14.1.

[faceoffers28]

Starting with the version of VIsual Studio before this last release, I noticed that I couldn't select the version of iOS to use once I selected Asp.net 7.

You can see the problem here. It still hasn't been fixed. I assume VS can't determine what version of .Net Maui is installed therefore it can't suggest the correct version of iOS to use. It appears that Microsoft has made the initial release of .Net Maui dependent on iOS 16.0. It also appears that Microsoft has made latest release of .Net Maui dependent on iOS 16.1.

I can manually edit the csproj and set iOS to 16.1, as shown below. When I try to Build, using Visual Studio, I get all kinds of errors.

<TargetFrameworks>net7.0-ios16.1;net7.0-android33.0</TargetFrameworks>

Bottom line, this is really messed up! I'm going to try to work through the 15 errors that were just introduced when I tried to upgrade to iOS 16.1. In the meantime, I'm getting closer to recreating the last successful .Net Maui Build using Azure DevOps. I'll keep experimenting with both seeing as I need to get this app built and uploaded to the App Store before the end of year.

[faceoffers28]

I changed up my Pipeline to try and recreate the last .Net Maui Build that worked. I'm trying to recreate the initial Asp.net 7.0 .Net Maui environment in Azure DevOps.

I was finally able to get my iOS app to Build using what I think is the configuration for the first .Net Maui release. This does not fix the current problem, but at least I can Build my app again.

Here is part of the script that I used.

Tell the Pipeline to use Asp.net 7.0.100.

- task: UseDotNet@2
  displayName: .NET Version
  inputs:
    packageType: 'sdk'
    version: '7.0.100'

Tell the Pipeline to use .Net Maui 7.0.1xx.

https://github.com/dotnet/maui/tree/release/7.0.1xx

This is where 7.0.1xx was upgraded to microsoft.net.sdk.ios version 16.0.1478.

dotnet/maui@e5c8224

- task: CmdLine@2
  displayName: 'Install Maui'
  inputs:
    script: 'dotnet workload install maui --from-rollback-file https://maui.blob.core.windows.net/metadata/rollbacks/7.0.1xx.json --source https://pkgs.dev.azure.com/dnceng/public/_packaging/dotnet7/nuget/v3/index.json --source https://api.nuget.org/v3/index.json'

Tell the Pipeline to use xamarin-sdk.sh 17_4_0_301. This was the last version of the Xamarin SDK before the upgrade to 17.4.3 .

- task: CmdLine@2
  displayName: 'Set Xamarin SDK'
  inputs:
    script: |      
      /bin/bash -c "sudo $AGENT_HOMEDIRECTORY/scripts/select-xamarin-sdk.sh 17_4_0_301"  

[trevortirrell]

This worked. Thank you! @faceoffers28

[mattjohnsonpint]

I was able to get the latest working on GitHub Actions with the following:

    - name: Set XCode Version
      if: runner.os == 'macOS'
      shell: bash
      run: |
        sudo xcode-select -s "/Applications/Xcode_14.1.app"
        echo "MD_APPLE_SDK_ROOT=/Applications/Xcode_14.1.app" >> $GITHUB_ENV

The MD_APPLE_SDK_ROOT environment variable sets the Xcode path used by Xamarin.

I thought it was supposed to use the result of xcode-select -p, but apparently not.

CC: @rolfbjarne

[rolfbjarne]

@mattjohnsonpint we check the following, in order:

1. The MD_APPLE_SDK_ROOT environment variable.
2. What's configured in ~/Library/Preferences/Xamarin/Settings.plist
3. xcode-select -p

[berhir]

Thank you @mattjohnsonpint, I can confirm that your solution works also with Azure Pipelines.
I can finally build our iOS app with the latest MAUI version. This is the Azure Pipelines task to set the XCode version:

  - task: Bash@3
    displayName: Set XCode Version
    inputs:
      targetType: 'inline'
      script: |
        sudo xcode-select -s "/Applications/Xcode_14.1.app"
        echo "##vso[task.setvariable variable=MD_APPLE_SDK_ROOT;]/Applications/Xcode_14.1.app"

[mattjohnsonpint]

we check the following, in order:

1. The MD_APPLE_SDK_ROOT environment variable.
2. What's configured in ~/Library/Preferences/Xamarin/Settings.plist
3. xcode-select -p

That makes sense. Just tested and the default currently on the macos-12 GHA runner image is MD_APPLE_SDK_ROOT not set, but both the ~/Library/Preferences/Xamarin/Settings.plist and xcode-select -p showing 14.0.1.

(On the macos-11 image, it's similar, but both are set to 13.2.1.)

Thus, using xcode-select -s alone is insufficient; one also needs to either set the environment variable or update the plist.

[mikhailkoliada]

Hello! Given all the above I am going to close the issue. Unfortunately, unlike GH actions, AzDo does not have a nice way (a task) to switch between xcode versions :(, nothing can be done on our side.

[Eilon]

The advice here worked for me. I use GitHub Actions to build a project based on .NET MAUI 7.x and has Windows and macOS builds to build all 4 main MAUI platforms (Windows, Android, iOS, macOS).

Here's what I ended up with in my YML file:

https://github.com/Eilon/HybridWebView/blob/4fcf89408bbfb38caa7edabf877f541cb8aaabcf/.github/workflows/_build.yml#L27-L41

[mattjohnsonpint]

@Eilon - Hi! 👋 I'm in a similar setup as you.

No need to go back to Xcode 14.1 at this point. You can use 14.2, and only a minimal rollback file is needed. See xamarin/xamarin-macios#17561 (comment)

It's only Xcode 14.3 that we can't use in Github Actions yet (unless you want to try the macos-13 runner, currently in beta).

The only real problem today is that the latest iOS and MacCatalyst dotnet workloads require Xcode 14.3, so don't work on the macos-12 runner. (It would be better if somehow we could have compatible workloads installed by default, without having to use rollback files.)
