Are all CI machines on Xcode 14.3? If so we can merge the fix to this #1051

[keith]

it looks like no, so that is kinda of hard to land since there isn't an easy way to conditionalize that setting based on the current Xcode version

[meteorcloudy]

We still have a few machines to update /cc @fweikert

There are still ongoing problems with Xcode: bazelbuild/continuous-integration#1431 (comment)

Closing this issue as the CI shows green now !
