Placeholder Attributes Not Correctly Set

Description

When making a forward Geocoding request, all the placemarks in the response should have their usual attributes (i.e. the attributes included in a vanilla cURL request to the Geocoding API). However, for some reason there are placemark attributes that are not being set.

Here's an example request:

        let options = ForwardGeocodeOptions(query: "Hong Kong")
        options.allowedScopes = [.place, .locality]
        options.maximumResultCount = 5
        geocodingDataTask = geocoder.geocode(options) { [unowned self] (placemarks, attribution, error) in
            if let error = error {
                NSLog("%@", error)
            } else if let placemarks = placemarks, !placemarks.isEmpty {
                for placemark in placemarks {
                    print(placemark.name)
                    print(placemark.code)
                    print(placemark.country?.code)
                    print(placemark.administrativeRegion?.address)
                }
            } else {
                self.resultsLabel.text = "No results"
            }
        }

Expected

In the Geocoding API playground, the result of a query with the same parameters includes "short_code" which should be the placemark.code value that is printed in the above code block.

Actual

When the above code block is run, all but placemark.name return nil values:

Hong Kong
nil
nil
nil

まず「Hong Kong,」に対する ForwardGeocodeOptions と geocoder.geocode の例を再現し、返された placemark を Geocoding API playground のレスポンスと比較します。forward-geocoding のレスポンスが placemark.name、placemark.code、country.code、administrativeRegion.address にどのように値を設定するかを追跡します。これらの期待される属性が nil でなくなれば完了です。
