visionOS SDKs missing

[noahsmartin]

Description

The visionOS SDKs seem to have gone missing from the macos14 GitHub action runners. A couple days ago it worked, today I get this error: { platform:visionOS, id:dvtdevice-DVTiOSDevicePlaceholder-xros:placeholder, name:Any visionOS Device, error:visionOS 1.2 is not installed. To use with Xcode, first download and install the platform }

This is with Xcode 15.4, I've also tried updated to 16.0 but get the error that visionOS 2.0 is not installed. You can see that issue here: https://github.com/EmergeTools/SnapshotPreviews-iOS/actions/runs/11056651930/job/30718675120?pr=202

Is there any way to build for visionOS is a GitHub action runner?

It should be installed

Actual behavior

It is not installed

i also have this issue, this is terrible

Hey there!

It's kinda expected behaviour. See details here:

• https://github.com/actions/runner-images/issues/10559

We'll keep this issue on board for better informing for some time.

TL;DR:

• macOS-14 images do not ship visionOS platform

Possible workarounds:

• to use macos-15 image
• to install visionOS in runtime with:

            sudo xcodebuild -runFirstLaunch
            sudo xcrun simctl list
            sudo xcodebuild -downloadPlatform visionOS
            sudo xcodebuild -runFirstLaunch

macos 15 works thanks

For those tracking these changes or encountering issues for the first time, here’s some context and clarification.

As you may know, we recently faced significant challenges where many users began running out of disk space during tests and builds on macOS-based runners. 😞 This issue was triggered by the inclusion of visionOS simulators in the latest Xcode builds. The root cause, however, lies in our policy of providing nearly all supported minor versions of Xcode on each macOS image, leading to steadily increasing disk usage as Apple’s ecosystem grows.

Here’s how we’ve approached resolving the issue so far:

• Immediate action: We temporarily stopped pre-installing visionOS platform tools in Xcode on macOS-14 images.
• Strategic adjustment: We introduced a policy to limit the number of major Xcode versions installed per macOS image, alongside reinstating visionOS tools for supported Xcode versions. This aimed to free up significant disk space. https://github.com/actions/runner-images/pull/10876

However, we’ve discovered that some projects rely on multiple major versions of Xcode simultaneously, making these strict measures overly restrictive. This prompted us to refine our strategy, prioritising functionality alongside disk space optimisation.

Current Strategy 📏

Our updated approach balances reducing installed Xcode versions with maintaining runner usability:

1. macOS-14 images:

• Will include all minor releases of Xcode 15 with the full platform tools suite (as before).
• Will now also include two minor releases of Xcode 16 (excluding visionOS tools). These will follow a “last two” principle, with the oldest replaced by the newest as updates are released. Beta versions will not be included. https://github.com/actions/runner-images/pull/10962

2. macOS-15 images:

• Will include all minor releases of Xcode 16 with the full platform tools suite (as before).
• Will also include the latest available release of Xcode 15 with the full platform tools suite. https://github.com/actions/runner-images/pull/11023

3. Disk Space and Future Adjustments:

• Currently, macOS-14 images have approximately 60 GB of free space. However, this is not a guaranteed figure and may decrease over time.
• When free space approaches 30 GB, we will reassess our policies and toolsets to ensure compliance with our promised minimum of 14 GB of free space.
• macOS-15 images are not currently impacted by this issue. However, with future Xcode updates, policies may need to be revisited. 🤷‍♂️

Recommendations 🦮

• If your workflows depend on visionOS, we recommend switching to macOS-15 images.
• If your tasks require significant disk space, consider preparing the runner by removing unnecessary large components before starting your workflows.
