Hello,
Upon registration to be able to localise the App for the users I am requesting the countryCode:
(Locale.current as NSLocale).object(forKey: NSLocale.Key.countryCode) as? String
Most of the values are the one expected ("US", "GB", "DE", ...), however in some cases I have numeric country codes like "419" or "241".
I wanted to know if this was expected and how I can make them fallback to the regular country code that are none numeric.
Thank you
Hi, I’d recommend using Locale.current.region which has many known values
https://developer.apple.com/documentation/foundation/locale/region#4063083
The locale cannot return a specific country, as for instance es_419 corresponds to Spanish in Latin America, so a variant used across multiple countries.
Bundle.preferredLocalizations(from: availableLocalizations, forPreferences: initialOrPreferredLocalization).first can compute fallbacks for you.
https://developer.apple.com/documentation/foundation/bundle/1409418-preferredlocalizations
Thanks very much for your prompt answer, will deep dive in the shared documentation and try it!
So this code:
let nsLocale = (Locale.current as NSLocale)
let countryCode = nsLocale.object(forKey: NSLocale.Key.countryCode) as? String
let languageCode = nsLocale.object(forKey: NSLocale.Key.languageCode) as? String
let currencyCode = nsLocale.object(forKey: NSLocale.Key.currencyCode) as? String
let localeCountryCode = nsLocale.countryCode
let systemLocaleCountryCode = nsLocale.countryCode
return """
Given countryCode: \(countryCode ?? "error")
languageCode: \(languageCode ?? "error")
currencyCode: \(currencyCode ?? "error")
otherCountryCode: \(localeCountryCode ?? "error")
systemCountryCode: \(systemLocaleCountryCode ?? "error")
"""
Give this output sometimes:
Given countryCode: 419
languageCode: en
currencyCode: error
otherCountryCode: 419
systemCountryCode: 419
And I don't understand why this would be the case.
Would you have any idea? Do you know what I can add to try to have a more accurate debugging?
Thank you
