How to get current language code with Swift?

Question

I want get the language code of the device (en, es...) in my app written with Swift. How can get this?

I\'m trying this:

var preferredLanguages : NSL         


        

Answer 1

Locale.current.languageCode returns me wrong code, so I use these extensions:

extension Locale {
    static var preferredLanguageCode: String {
        let defaultLanguage = "en"
        let preferredLanguage = preferredLanguages.first ?? defaultLanguage
        return Locale(identifier: preferredLanguage).languageCode ?? defaultLanguage
    }

    static var preferredLanguageCodes: [String] {
        return Locale.preferredLanguages.compactMap({Locale(identifier: $0).languageCode})
    }
}
