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

You can get a list of countries using the NSLocale class's isoCountryCodes which returns an array of [String]. From there, you get the country name by using NSLocale's displayName(forKey:) method. It looks like this:

var countries: [String] = []for code in NSLocale.isoCountryCodes  {    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)

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)

Swift 4.2

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