Get a country unique identifier on user tap

When a user taps a particular place on a MapKit map, I need to know if a country is a particular country (eg. Spain), then I must perform actions based on the retrieved information.

I initially thought to use the country name I get from: 

reverseGeocodeLocation(_ location: CLLocation, 
          completionHandler: @escaping CLGeocodeCompletionHandler)

but the country name is strictly related to the device locale settings, so it's not really a good idea use the country name...

Then, I thought getting the isoCountryCode would have been a better choice, but, I don't know why in my tests CLPlacemark doesn't return it.

Finally, there's another version of the CLGeocoder().reverseGeocodeLocation function, that lets you specify a preferredLocale. Is this the way to go?

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

To get address info from lat & long,

Swift

     let loc: CLLocation = CLLocation(latitude:center.latitude, longitude: center.longitude)

    geoCoder.reverseGeocodeLocation(loc, completionHandler:
        {(placemarks, error) in
            if (error != nil)
            {
                print("reverse geodcode fail: \(error!.localizedDescription)")
            }
            let pm = placemarks! as [CLPlacemark]

            if pm.count > 0 {
                let pm = placemarks![0]
                print(pm.country)
                print(pm.ISOcountryCode)
          }
    })

}

Obj-C

  CLGeocoder *geocoder = [[CLGeocoder alloc] init] ;
        __block CLPlacemark *placemark = nil;

        [geocoder reverseGeocodeLocation:currentLocation
                       completionHandler:^(NSArray *placemarks, NSError *error)
         {
             if (error){

                 NSLog(@"************************************* Geocode failed with error:************************************* \n %@", error);
             }else{
             placemark = [placemarks objectAtIndex:0];
             NSLog(@"Current placemark %@", placemark);
             NSLog(@"Current country code: %@", [placemark ISOcountryCode]);
          }
         }];
