The selected answer returns the current device language, but not the actual language used in the app. If you don't provide a localization in your app for the user's preferred language, the first localization available, ordered by the user's preferred order, is used.

Swift:

let language = NSBundle.mainBundle().preferredLocalizations.first as NSString
