We recently introduced Swift into a legacy Objective-C project and its been working well enough on our local machines, but an existing Xcode Bot has started failing due to "'Coach-Swift.h' file not found." (Coach is the name of the project and target.)
A local build on the same machine runs successfully, but a newly-created bot fails with the same error.
I have tried to confirm the bot is using the same target, scheme, and configuration as the local build and it seems to all be the same, is there anything else I can try to check or change to try and restore the functionality?
