This will happen for me if I build Release twice in a row without deleting the application in between.

What happens is the first command to build will build and link the application, create the xSYM file and then strip the application.

The second build command will skip building and linking since it is up to date but will perform the xSYM step which will create an empty xSYM since the previously built application was stripped at the end :)

The take hope message I learned the last time this happened to me (having an unexpectedly empty xSYM. Luckily it was just an internal build and nothing we had shipped) was that release that might actually leave my own machine should be build after a full clean (or at least delete the application binary so Xcode re-links it and puts the symbols back in).

Hope this helps.

Thierry

Thanks, Jason. Indeed, dwarfdump thinks that my dSYM is empty:
