In Github CI this solution seems not to work. I tried this

 - name: Skip SwiftPM plugin trust validation (system)
      run: |
        set -euo pipefail
        sudo defaults write /Library/Preferences/com.apple.dt.Xcode IDESkipPackagePluginFingerprintValidation -bool YES

However I still get the error:

Validate plug-in “OpenAPIGenerator” in package “swift-openapi-generator”
error: “OpenAPIGenerator” must be enabled before it can be used
** BUILD INTERRUPTED **


The following build commands failed:
    Validate plug-in “OpenAPIGenerator” in package “swift-openapi-generator”
