Setup below configuration in your base viewcontroller

Create object of  CountriesViewController 
For Example,
 var countriesViewController = CountriesViewController()

e.g.

@IBAction func btnCountryPicker(_ sender: UIButton) {

    DispatchQueue.main.async {
        CountriesViewController.show(countriesViewController: self.countriesViewController, toVar: self)
    }
}

1. Will call when multiple countries can be selected func countriesViewController(_ countriesViewController: CountriesViewController, didSelectCountries countries: [Country])
2. Will call when user cancel and close country picker func countriesViewControllerDidCancel(_ countriesViewController: CountriesViewController)
3. Will call when country is selected func countriesViewController(_ countriesViewController: CountriesViewController, didSelectCountry country: Country)
4. Will call when user deselect country func countriesViewController(_ countriesViewController: CountriesViewController, didUnselectCountry country: Country)

e.g.

func setupCountryPicker(){
   self.countriesViewController = CountriesViewController()
   self.countriesViewController.delegate = self
   self.countriesViewController.allowMultipleSelection = false
   if let info = self.getCountryAndName() {
       countryCode = info.countryCode!
       self.lblFlag.text = info.countryFlag!
       self.lblCountryCode.text = info.countryCode!
   }
}

e.g.

var countries: [Country] = []
countries.append(Country(countryCode: "AF", phoneExtension: "93", isMain: true, flag: emojiFlag(countryCode: "AF")))

e.g.

open class func emojiFlag(countryCode: String) -> String {
let base : UInt32 = 127397
var string = ""
let country = countryCode.uppercased().unicodeScalars
for uS in country {
    print("country code:\(countryCode.uppercased())---\(UnicodeScalar(base + uS.value)!)")
    string.unicodeScalars.append(UnicodeScalar(base + uS.value)!)
}

return string

}

var selectedCountry:CountryModel?

private func getCountryAndName(_ countryParam: String? = nil) -> CountryModel?

func isValidPhone(phone: String) -> Bool {
    let phoneRegex = "^[0-9+]{0,1}+[0-9]{9}$"
    let phoneTest = NSPredicate(format: "SELF MATCHES %@", phoneRegex)
    return phoneTest.evaluate(with: phone)
}
