    I think the best option for me here is to generate the code myself. To help with this I have created an extension on Locale:

    extension Locale {
        var iso3166code: String {
                let language = languageCode,
                let region = regionCode
                else { return "en-US" }
            return "\(language)-\(region)"

    While this is accurate enough for my purposes, you should probably ensure it returns expected values for your project.
