Null value returns from AddressBook framework in swift

Question

In my swift app, I am retrieving AddressBook contacts from AddressBook framework. Contacts are retrieved successfully except the following case.

Case 1:

If I save a contact number alone without contact name to AddressBook, contact is successfully added.

But, If I try to retrieve that contact which does not having name, App crashes, saying that fatal error received.

Coding:

var contactName: String = ABRecordCopyCompositeName(addressBookRecord).takeRetainedValue() as NSString as String

I don't know how to handle this null value exception. Kindly guide me, how to solve this.

Why don't you check if contactName returns null and assign it an empty string if that is the case? something like this http://paste.ubuntu.com/12695416/ — NSNoob, Oct 06 '15 at 07:17
You should take a look at the new contact framework https://developer.apple.com/library/prerelease/mac/documentation/Contacts/Reference/Contacts_Framework/index.html — Leo Dabus, Oct 06 '15 at 07:18

This code will not crash if you got any contact without name:

func processAddressbookRecord(addressBookRecord: ABRecordRef) {

    let addressBookRef: ABAddressBookRef = ABAddressBookCreateWithOptions(nil, nil).takeRetainedValue()

    let people:NSArray = ABAddressBookCopyArrayOfAllPeople(addressBookRef).takeRetainedValue();

    for person in people{
        if  let name:String = ABRecordCopyValue(person, kABPersonFirstNameProperty)?.takeRetainedValue() as? String {
            let numbers:ABMultiValue = ABRecordCopyValue(person, kABPersonPhoneProperty).takeRetainedValue()

            if let number:String = ABMultiValueCopyValueAtIndex(numbers,0)?.takeRetainedValue() as? String {
                print("number = \(number)");
                arrayOfContacts.addObject(["\(name)":"\(number)"]);
            }
        }
    }
}
