No artifacts available from Build for Simulator step

I’m trying to produce a simulator build to share internally however when using the “build for simulator” step along with “deploy to bitrise” there are no artefacts available after the run completes.

There are no errors in either step and the logs are indicating that the build for simulator step is copying the output correctly into the deploy directory but that directory is empty when the deploy the bitrise step runs.

Link to run here Bitrise - Mobile Continuous Integration and Delivery - iOS & Android Build Automation
