</span>Most of the recent builds appear to be working:<br>

<br>
</span>What version of the 'swift' project do you have checked out? Have you done a clean/reset to make sure those aren't issues at the moment?<br>
<br>
You can run swift/utils/update-checkout --clean --reset-to-remote --scheme master (which will get rid of any cruft if you haven't got anything you need to keep) and then re-run the build to see if that resolves the errors.<br>
