How to get a CNContact phone number(s) as string in Swift?

Question

I am attempting to retrieve the names and phone number(s) of all contacts and put them into arrays with Swift in iOS. I have made it this far:

Answer 1

Here's a Swift 5 solution.

import Contacts

func sendMessageTo(_ contact: CNContact) {

    let validTypes = [
        CNLabelPhoneNumberiPhone,
        CNLabelPhoneNumberMobile,
        CNLabelPhoneNumberMain
    ]

    let numbers = contact.phoneNumbers.compactMap { phoneNumber -> String? in
        guard let label = phoneNumber.label, validTypes.contains(label) else { return nil }
        return phoneNumber.value.stringValue
    }

    guard !numbers.isEmpty else { return }

    // process/use your numbers for this contact here
    DispatchQueue.main.async {
        self.sendSMSText(numbers)
    }
}

You can find available values for the validTypes array in the CNPhoneNumber header file.

They are:

CNLabelPhoneNumberiPhone
CNLabelPhoneNumberMobile
CNLabelPhoneNumberMain
CNLabelPhoneNumberHomeFax
CNLabelPhoneNumberWorkFax
CNLabelPhoneNumberOtherFax
CNLabelPhoneNumberPager
