Since update to Xcode 6.1 yesterday there is no correct localization of apps in the iOS Simulator. I switched the language and region to German/Germany and my apps are still in English and only English keyboard is available. Localization was fine in Xcode 6.0.1 and iOS 8.0 Simulator.
Does anybody have similar problems?
One possible work around is to set the "Application Language" in the used scheme.
This was mentioned in the Xcode 6.1 Release Notes
In some situations, [NSLocale currentLocale] may return en_US instead of the chosen locale in the iOS 8.1 simulator.
I just do by above answer AlexVoge. Beginner maybe need a picture :]
