How to permanently set the iOS Simulator to a different language than english

Question

I'm developing an app that mainly uses the German language. Because of that, I would like to have the iOS Simulator to be set to German language by default. If I start the iOS Simulator having the language of MacOS set to German, the Menu language of the Simulator is German, but the language 'inside' the simulated iOS is English. I know, that I can change the language within the simulated iOS. But thats not what I'm looking for, because after a reset of the simulator I have to set the language again, and also changing the simulated language seems to be very buggy in iOS 4.2 (frequently leading to hard crashes of MacOS).

Is there a way (maybe via the command line) to permanently change the default language of the simulator?

Many thanks in advance.

Answer 1

As seen in the iOS7 TechTalks Video "Hidden iOS Developer Gems", you can set two properties in the build scheme so that the simulator changes to your selected language and region:

That way you can also easily add multiple run schemes if you need to test different languages each time and quickly switch them before running.

Edit: As of Xcode 6, you can edit this information directly through the run schemes options. Just select "Application Language" and/or "Application Region".

You could make yourself a script using ios-sim-locale to set simulator options if the locale settings are lost. See ios-sim-locale. This way you only would need to execute the script before starting the simulator.
