Update Swift 4:

Just use this code to force the data returned in English:

func fetchCityAndCountry(from location: CLLocation, completion: @escaping (_ locality: String?, _ country:  String?, _ error: Error?) -> ()) {
    CLGeocoder().reverseGeocodeLocation(location, preferredLocale: Locale.init(identifier: "en")) { placemarks, error in
        completion(placemarks?.first?.locality,
                   placemarks?.first?.country,
                   error)
    }
}

You can change the Locale identifier to translate the data into any other language ("ca", "es", "fr", "de"...).

This function can be called, for instance, like this:

fetchCityAndCountry (from: userLocationCL) { locality, country, error in
   guard let locality = locality, let country = country, error == nil else { return }
   // your code
}

Where userLocationCL is the current user location.
