iOS 11 has a new -reverseGeocode... method that accepts a locale to use:

- (void)reverseGeocodeLocation:(CLLocation *)location preferredLocale:(NSLocale *)locale
    completionHandler:(CLGeocodeCompletionHandler)completionHandler

Swift signature:

func reverseGeocodeLocation(_ location: CLLocation, preferredLocale locale: Locale?, completionHandler: @escaping CLGeocodeCompletionHandler)

Put whatever locale you like. This example just uses the current locale

NSLocale *currentLocale = [NSLocale currentLocale];
[self.geocoder reverseGeocodeLocation:self.location preferredLocale:currentLocale
    completionHandler:^(NSArray * _Nullable placemarks, NSError * _Nullable error) {

    // Handle the result or error
}];
