Xcode Cloud issue (ibtoold crash?)

Hi, we need some more diagnostics to be able to help you with this. Could you please file a feedback request and post the number here so we can examine the logs? Be sure to include your team ID and the link to the build also. You can file Xcode Cloud specific feedback using these steps.

@xcc-developer Hi, thanks for the answer. I'm using the steps you linked in order to send Xcode Cloud specific feedback, but when I try to submit it says that the attachments might contain personal or sensitive information, and that will be used to train machine learning models.

I'm not sure about the attachments, so I'd like to understand which attachments are absolutely necessary, and which can be skipped. For example, can I limit the attachments to just the "Xcode Cloud diagnostics" folder (which contains the build artifacts)? Thanks

@xcc-developer I filed a feedback request and attached the Xcode Cloud diagnostics that contain the build logs.

The feedback request number is FB20676007

We also have a similar repeated issue. Everything is archiving in xcode cloud but then on step "Preparing build for App Store Connect failed" action fails and in logs there is ibtool crash ExcUserFault_ibtoold-2025-10-16-082310.ips.

The feedback request number is FB20699169

We had one dynamic xcode target framework embedded both into app target and widget target. When I removed embedding from widget, ibtool stopped crashing for some reason.

I thought that if xcode cloud workflow fails on stage "Preparing build for App Store Connect failed" then build is not uploaded at all.

But turns out that app store connect has all the details about the error for each such failed build in TestFlight builds section.

So just go and check in App Store Connect, when you see this mysterious ibtool crash in xcode cloud.

In our case, the error happens in a workflow that only run tests, doesn't upload a build.
