Metal is not installed on Xcode 26 on Xcode Cloud

Hi there,

We’re encountering this error in all of our builds when using the latest Xcode and macOS:

The Metal Toolchain was not installed and could not compile the Metal source files. Download the Metal Toolchain from Xcode > Settings > Components and try again.

In short, all builds are failing. I’ve tried fixing this by installing Metal and applying other solutions, but none of them worked reliably.

Is there a way to ensure that the Metal Toolchain is installed on the CI machine?

Please file a Feedback report using Feedback Assistant.

@DTS Engineer Thanks! I'm hitting this as well and just filed. I reproduce this 100% of the time.
