I am trying to implement the Country Codes in my app for Phone Auth Login. This is a SwiftUI app using iOS 17 and below is the code i am using to implement this but it is printing out the full Country Name rather than the 2 letters of the country as listed at Country Codes.

I was able to find some information at a previous post by another user:
Getting country name from country code but this just displayed the Country in full name and not in the 2-letter format.

Below is the Code acquired:

Getting Country Code:

func getCountryCode() -> String {
        let regionCode = Locale.current.region?.identifier ?? ""
        return countries[regionCode] ?? ""
    }

Getting Country Name:

func countryName(countryCode: String) -> String? {
    let current = Locale(identifier: Locale.current.identifier)
    return current.localizedString(forRegionCode: countryCode)
}

Implementing code in my LoginView:

HStack {
    // displays CountryName: full NOT 2-letter identifier
    Text("(loginData.countryName(countryCode: regionCode) ?? "")")
    
    // displays CountryCode
    Text("+ (loginData.getCountryCode())")
}
                            

When i display the above in my app, this is how it is displayed:

United States  +1

How I need it displayed:

US +1
