Could you please help on how to get country code using NSLocale in Swift 3 ?
This is the previous code I have been using.
NSLocale.currentLocale().objectForKey(NSLocaleCountryCode) as! String
I can get Language Code as below in Swift 3.
Locale.current.languageCode!
As I can see, fetching languageCode is straight forward but countryCode property is not available.
You can use regionCode property on Locale struct.
Locale.current.regionCode
It is not documented as a substitute for old NSLocaleCountryCode construct but it looks like it is. The following code checks countryCodes for all known locales and compares them with regionCodes. They are identical.
public func ==(lhs: [String?], rhs: [String?]) -> Bool {
guard lhs.count == rhs.count else { return false }
for (left, right) in zip(lhs, rhs) {
if left != right {
return false
}
}
return true
}
let newIdentifiers = Locale.availableIdentifiers
let newLocales = newIdentifiers.map { Locale(identifier: $0) }
let newCountryCodes = newLocales.map { $0.regionCode }
let oldIdentifiers = NSLocale.availableLocaleIdentifiers
newIdentifiers == oldIdentifiers // true
let oldLocales = oldIdentifiers.map { NSLocale(localeIdentifier: $0) }
let oldLocalesConverted = oldLocales.map { $0 as Locale }
newLocales == oldLocalesConverted // true
let oldComponents = oldIdentifiers.map { NSLocale.components(fromLocaleIdentifier: $0) }
let oldCountryCodes = oldComponents.map { $0[NSLocale.Key.countryCode.rawValue] }
newCountryCodes == oldCountryCodes // true
See Wojciech N.'s answer for a simpler solution!
Similarly as in NSLocale Swift 3, you have to cast the overlay type Locale back to its
Foundation counterpart NSLocale in order to retrieve the country code:
if let countryCode = (Locale.current as NSLocale).object(forKey: .countryCode) as? String {
print(countryCode)
}
If you make sure that you're using an NSLocale and not a Locale instance, you can use the countryCode property:
let locale: NSLocale = NSLocale.current as NSLocale
let country: String? = locale.countryCode
print(country ?? "no country")
// > Prints "IE" or some other country code
If you try to use countryCode with a Swift Locale Xcode will give you an error with a suggestion to use regionCode instead:
let swiftLocale: Locale = Locale.current
let swiftCountry: String? = swiftLocale.countryCode
// > Error "countryCode' is unavailable: use regionCode instead"
NSLocale.countryCode is the same as Locale.regionCode
This is from apple implementation of Locale. Locale.swift
/// Returns the region code of the locale, or nil if it has none.
///
/// For example, for the locale "zh-Hant-HK", returns "HK".
public var regionCode: String? {
// n.b. this is called countryCode in ObjC
if let result = _wrapped.object(forKey: .countryCode) as? String {
if result.isEmpty {
return nil
} else {
return result
}
} else {
return nil
}
}
print(Locale.current.region?.identifier)
print(Locale.current.regionCode)
var localCode: String? = ""
if #available(iOS 16, *) {
localCode = Locale.current.region?.identifier
} else {
localCode = Locale.current.regionCode
}
print(localCode)
//MARK:- Get both country code and Mobile Phone number code
var sendPhoneNumber = ""
if let countryCode = (Locale.current as NSLocale).object(forKey: .countryCode) as? String {
print(countryCode)
if countryCode != ""
{
let getCode = self.getCountryPhonceCode(countryCode)
if getCode != ""
{
sendPhoneNumber = getCode + tfMobileNumber.text!
getOTP(getPhoneNumber: sendPhoneNumber)
}
}
}
