Another function for turning a two-letter country code into its emoji flag using Swift 5.

internal func getFlag(from countryCode: String) -> String {

    return countryCode
        .unicodeScalars
        .map({ 127397 + $0.value })
        .compactMap(UnicodeScalar.init)
        .map(String.init)
        .joined()
}
