[azure devops] AVPIdentity: AppleVirtualPlatformHostKey.mm:234: Assert: platformExpert, value: 0

[jeromelaban]

Description

When starting the iOS simulators on macos-15, the following assertion happens:

AVPIdentity: AppleVirtualPlatformHostKey.mm:234: Assert: platformExpert,  value: 0
AVPIdentity: AppleVirtualPlatformHostKey.mm:234: Failed to get AppleVirtualPlatformARMPE service.

The message shows up as stdout, "polluting" machine readable outputs like simctl.

This is azure devops specific, this does not happen on github actions with macos-15.

Is it regression?

Not for this image, but compared to other images, yes.

Expected behavior

No assertions in the log

Actual behavior

Many messages like this one:

AVPIdentity: AppleVirtualPlatformHostKey.mm:234: Assert: platformExpert,  value: 0

@jeromelaban We will look into the issue and keep you posted with updates.

We noticed the same issue happening in our e2e pipeline starting yesterday with macOS-15 as well. It happens with both iOS 18.0 and 18.1 Simulators.

[albertoAround]

Same problem here. Any news? It's kinda blocking

Hi All, We are still investigating the issue. Will keep you posted with updates soon.

[sanket492]

Observed this issue today and all our build and automation pipelines are failing. @sureshe456 @susmitamane please fix this issue.

[albertoAround]

Is there an ETA? We're in serious troubles and we're starting to consider rolling back to physical device for building @sureshe456 @susmitamane

[sureshe456]

Hi All, We are still checking on it. will be posted any updates.

[sureshe456]

Hi @jeromelaban,
Based on the analysis, the macos-15-large (macos-15) is based on an AMD64 processor, while the macos-15-xlarge (macos-15-arm64) is based on an ARM64 processor. The AppleVirtualPlatformARMPE service is specifically designed for Apple Silicon (ARM-based) processors, such as the M1, M1 Pro, M1 Max, M2, and later chips. It is not compatible with AMD64 (x86_64) processors.
Therefore, when you start iOS simulators on macos-15 (AMD64 processor), then AppleVirtualPlatformARMPE service will be inaccessible. However, this service will be accessible on the macos-15-xlarge (macos-15-arm64) image.

[albertoAround]

So what kind of image do we have to type? I tried macos-15-arm64 and macos-15-xlarge but I received for both the same error

"No config name or imagelabel provided in request" @sureshe456

[sureshe456]

For macOS 15 Arm64: Please try with this macos-15.
FYI...

[albertoAround]

We're working on Azure hosted images. So here are the ones that we can pick https://learn.microsoft.com/en-us/azure/devops/pipelines/agents/hosted?view=azure-devops&tabs=yaml

There is no macos-15-large or xlarge. @sureshe456

[jeromelaban]

Therefore, when you start iOS simulators on macos-15 (AMD64 processor), then AppleVirtualPlatformARMPE service will be inaccessible. However, this service will be accessible on the macos-15-xlarge (macos-15-arm64) image.

This could make sense, however, even selecting iPad (10th generation) does not work.

Also, regardless of the selected emulator, even running xcrun simctl list devices --json will emit the messages.

Furthermore, as noted by others in the thread, the images you mention are not on azure devops, only GHA.

[topi-identio]

The Simulators worked fine the day before this issue was posted. What changed? Did something update?

[albertoAround]

I mean, it's two weeks that we can't build... From such a large company it's almost unbelievable and we are paying for this service.

[sureshe456]

Hi All, We apologize for the inconvenience and understand the frustration this has caused. There was an issue with patches update on macOS 15 image generation.So, our team is actively working on resolving the issue, and we appreciate your patience during this time. Thank you for bringing this to our attention. We will keep you updated with any new information.Thanks.

Exactly same problem here, but getting this on Azure DevOps, after XCode 16 was removed from MacOS 15 build agents, and we had to specify MacOS 15 instead to use XCode 16.

AVPIdentity: AppleVirtualPlatformHostKey.mm:234: Assert: platformExpert,  value: 0
AVPIdentity: AppleVirtualPlatformHostKey.mm:234: Failed to get AppleVirtualPlatformARMPE service.
** ARCHIVE FAILED **

It only seems to happen on Mac OS 15 images that are on version 15.0.1. Specifically: https://github.com/actions/runner-images/releases/tag/macos-15%2F20241022.244

However, the same image tag 'macOS-15' sometimes results in an agent which has Mac OS 15.1 installed, see
here: https://github.com/actions/runner-images/releases/tag/macos-15%2F20241106.316

So the solution may just be to ensure all 'macOS-15' agents on Azure DevOps (and possibly on for Github actions agents too) are updated to MacOS 15.1 (image version 20241106.316) minimum.

Hope that helps!
