@mattrighetti Can you run the following command locally without issues?
xcodebuild -project HNWidgets.xcodeproj -scheme HNWidgets -destination platform=iOS\ Simulator,name=iPhone\ 16 -sdk iphonesimulator test?

In general, this sounds more like an Xcode issue, than an issue with this action. The command above is exactly what this action runs. So I assume it's an issue with the runner (e.g. I saw you just use the default Xcode that is set up, which might not match your project) or the project.

[mattrighetti]

Yeah the command runs fine on my Mac, what I did indeed was replicate what I use locally in this action but the runner complains 🫠

Are you using the same Xcode version?
The macos-latest (which currently resolves to macOS 14 ARM64) is currently using Xcode 15.4 by default.

I've also found the following results related to the error:

• https://stackoverflow.com/questions/78984326/cocoapods-pod-init-fails-with-unknown-isa-pbxfilesystemsynchronizedrootgroup-e
• PBXFileSystemSynchronizedRootGroup causing pod init to fail with CocoaPods 1.15.2a CocoaPods/CocoaPods#12627
• PBXGroup attempted to initialize an object with unknown ISA PBXFileSystemSynchronizedRootGroup fastlane/fastlane#25607

So it sounds like an issue with the Xcode project file.
