HI @AkihiroSuda, We will look into the issue and keep you posted with updates.

Hi @AkihiroSuda, The error is coming because of Xcode CLT was updated from 16.0 to 16.1.

To find the macOS 15 arm64 SDKs, we need to select the xcode version as 16.1. Please find the code below. Our readme file is in accordance with the below:

  - name: Get SDKs
      run: |
           sudo xcode-select -s /Applications/Xcode_16.1.app/Contents/Developer
           xcodebuild -showsdks

  - name: SDK
      run : xcrun --show-sdk-version

Output:

Hope this resolves issue ! Please free to reach out if any further questions.

Thanks, is there any intentional reason that 16.1 isn't selected by default?

Yes, we leave it to the users. Switching the default version on our side does not make much sense - each user is free to choose the version of Xcode they need. We usually do this either upon request (usually due to some very global issues in a specific release) or after the release of new minor versions is completed (for example, for version 15.4).
