How to retrieve phone number from Contacts framework - swift

Question

New to contacts trying to retrieve Mobile Phone number. I have address name email but cannot figure out mobile phone. This is what I got. The portion marked with ** is where I am going wrong.
if let oldContact = self.contactItem {
let store = CNContactStore()
do {
let mykeysToFetch = [CNContactFormatter.descriptorForRequiredKeysForStyle(.FullName), CNContactEmailAddressesKey, CNContactPostalAddressesKey,CNContactImageDataKey, CNContactImageDataAvailableKey,CNContactPhoneNumbersKey]
let contact = try store.unifiedContactWithIdentifier(oldContact.identifier, keysToFetch: mykeysToFetch)
dispatch_async(dispatch_get_main_queue(), { () -> Void in
if contact.imageDataAvailable {
if let data = contact.imageData {
self.contactImage.image = UIImage(data: data)
}
}
self.fullName.text = CNContactFormatter().stringFromContact(contact)
self.email.text = contact.emailAddresses.first?.value as? String
self.phoneNumber.text = contact.phoneNumbers.first?.value as? String
**if contact.isKeyAvailable(CNContactPhoneNumbersKey){
if let phoneNum = contact.phoneNumbers.first?.value as? String {
self.phoneNumber.text = phoneNum as String
}
}**
if contact.isKeyAvailable(CNContactPostalAddressesKey) {
if let postalAddress = contact.postalAddresses.first?.value as? CNPostalAddress {
self.address.text = CNPostalAddressFormatter().stringFromPostalAddress(postalAddress)
} else {
self.address.text = "No Address"
}
}
})
} catch {
print(error)
}
}

If you want a list of the mobile phones for a contact, you look at phoneNumbers which is an array of CNLabeledValue, and find those with a label of CNLabelPhoneNumberMobile or CNLabelPhoneNumberiPhone.
For example, you could do something like:
let mobilePhoneLabels = Set<String>(arrayLiteral: CNLabelPhoneNumberMobile, CNLabelPhoneNumberiPhone, "cell", "mobile") // use whatever you want here; you might want to include a few strings like shown here to catch any common custom permutations user may have used
let mobileNumbers = contact.phoneNumbers.filter { mobilePhoneLabels.contains($0.label) && $0.value is CNPhoneNumber }
.map { ($0.value as! CNPhoneNumber).stringValue }
So if you want the first one:
let mobileNumber = mobileNumbers.first ?? "" // or use `if let` syntax
Or if you want a string representation of the list of them:
let mobileNumberString = mobileNumbers.joinWithSeparator(" ; ")
What you do with this array of mobile numbers is up to you, but hopefully this illustrates the basic idea.
