I have come across the other threads and was unable to find a solution specific to my situation.
I have three config files (DEV, QA, Prod)
In each of the xcconfig files, I override the $(product_name) ex: PRODUCT_NAME = MyNameDev
This works great but now I need to localize the app in two languages and in 3 different environments.
In english:
Prod -> MyName
DEV -> MyNameDev
QA -> MyNameQA
In French:
Prod -> MyFrenchName
DEV -> MyFrenchNamepDev
QA -> MyFrenchNameQA
