When I develop a Mac app with localized interface with Xcode, I tend to modify the English resources and have them localized/translated only when the rest of the development work is done. Being on a non-English system, when I ask Xcode to run the app, it uses the localization to my own language, when I would want to choose myself (and choose English, in most cases).
So, how do I tell Xcode what language I want the app in during debug sessions?
You are probably looking for an answer for Xcode 4.X but I hope that this will help.
In Xcode 3.2.6 in the Groups & Files section of the project window open up the Executable section. Select the executable you want to run in English, and do command I. Click on the “Arguments” tab and then click on the + at the bottom. Then add:
-AppleLanguages “English”
as an argument.
