How do I get a list of countries in Swift ios?

Question

I\'ve already seen two similar questions to mine, but the answers for those questions do not work for me. I have an old project with a list of countries manually typed out insid

Answer 1

SWIFT 3 and 4

var countries: [String] = []

for code in NSLocale.isoCountryCodes as [String] {
    let id = NSLocale.localeIdentifier(fromComponents: [NSLocale.Key.countryCode.rawValue: code])
    let name = NSLocale(localeIdentifier: "en_UK").displayName(forKey: NSLocale.Key.identifier, value: id) ?? "Country not found for code: \(code)"
    countries.append(name)
}

print(countries)

Answer 2

Here is code for Swift 5.1 (well at least that works for me as a lot of functions has been renamed):

let array = NSLocale.isoCountryCodes.map
{
        (code:String) -> String in
        
        let id = NSLocale.localeIdentifier(fromComponents: [NSLocale.Key.countryCode.rawValue: code])
        let currentLocaleID = NSLocale.current.identifier
        return NSLocale(localeIdentifier: currentLocaleID).displayName(forKey: NSLocale.Key.identifier, value: id) ?? "Country not found for code: \(code)"
}

array here is an [String]

Answer 3

Swift 4.2

let languageList = Locale.isoLanguageCodes.compactMap { Locale.current.localizedString(forLanguageCode: $0) }
let countryList = Locale.isoRegionCodes.compactMap { Locale.current.localizedString(forRegionCode: $0) }

Answer 4

Here is @vedo27 's answer in Swift 3

 let countries = NSLocale.isoCountryCodes.map { (code:String) -> String in
    let id = NSLocale.localeIdentifier(fromComponents: [NSLocale.Key.countryCode.rawValue: code])
    return NSLocale(localeIdentifier: "en_US").displayName(forKey: NSLocale.Key.identifier, value: id) ?? "Country not found for code: \(code)"
}

Answer 5

Swift 3 declared as a var:

var countries: [String] {
    let myLanguageId = "en" // in which language I want to show the list
    return NSLocale.isoCountryCodes.map {
        return NSLocale(localeIdentifier: myLanguageId).localizedString(forCountryCode: $0) ?? $0
    }
}

Answer 6

Alternatively, you can have it in swift 4 and localized by the system language.

import Foundation

struct Country {
  let name: String
  let code: String
}

final class CountryHelper {
  class func allCountries() -> [Country] {
    var countries = [Country]()

    for code in Locale.isoRegionCodes as [String] {
      if let name = Locale.autoupdatingCurrent.localizedString(forRegionCode: code) {
        countries.append(Country(name: name, code: code))
      }
    }

    return countries
  }
}
