In CNContactPickerDelegate I can get CNContactProperty. From CNContactProperty How to get Country Code like +91, +1, +65 from the country name like IN, US, SG
func contactPicker(_ picker: CNContactPickerViewController, didSelect contactProperty: CNContactProperty) {
let FulMobNumVar = contactProperty.contact.phoneNumbers.first?.value
let countryCode = FulMobNumVar?.value(forKey: "countryCode") as? String
print("countryCode : \(countryCode!)")
}
Output : countryCode : in

Based on your question CNContactProperty does not provided any related details for fetch details directly. but in here you could use via RegEX or alternate local variable for get dial code.
for e.g :
func contactPicker(_ picker: CNContactPickerViewController, didSelect contacts: [CNContact]) {
contacts.forEach { contact in
for number in contact.phoneNumbers {
let phoneNumber = number.value
print("number is = \(phoneNumber)")
//Option 1: using Regex
let matched = matches(for:"\\+[0-9]{1,3}", in: phoneNumber.stringValue)
if !matched.isEmpty { print(matched.first as! String) }
let countryCode = phoneNumber.value(forKey: "countryCode") as? String
//Option 2: using Methods
// convert your countryCode to UPPER Case
let getCountryDialCode = getCountryPhonceCode((countryCode?.uppercased())!)
print("countryCode : \(countryCode!), getCountryDialCode : \(getCountryDialCode)")
}
}
}
func contactPickerDidCancel(_ picker: CNContactPickerViewController) {
print("Cancel Contact Picker")
}
for Regex purpose I taken the answer from here
// MARK: - get Matched results using Regex
func matches(for regex: String, in text: String) -> [String] {
do {
let regex = try NSRegularExpression(pattern: regex)
let results = regex.matches(in: text,
range: NSRange(text.startIndex..., in: text))
return results.map {
String(text[Range($0.range, in: text)!])
}
} catch let error {
print("invalid regex: \(error.localizedDescription)")
return []
}
}
for Local methods purpose I taken the answer from here
// MARK: - get Matched results using methods
func getCountryPhonceCode (_ country : String) -> String
