ABAddressBookCopyArrayOfAllPeople not getting contacts stored on SIM Card

Question

I'm using the code provided from the accepted answer at Retrieve all contacts phone numbers in iOS and I've noticed a lot of contacts are missing. I'm pretty sure they're contacts stored on the SIM card and somehow ABAddressBookCopyArrayOfAllPeople doesn't retrieve contacts from the SIM card. If I use ABPeoplePickerNavigationController the contacts do appear, but that isn't suitable for what I'm building.

Does anyone know how to overcome this issue?

Thanks

Missing contacts in ABAddressBookCopyArrayOfAllPeople had the answer. Although it wasn't entirely clear at first what the poster did, the main thing was casting the ABMultiValueRef to an NSArray like so:

ABMultiValueRef phones = (__bridge ABMultiValueRef)((__bridge NSString*)ABRecordCopyValue(ref, kABPersonPhoneProperty));
NSArray *phoneNumbers = (__bridge NSArray *)ABMultiValueCopyArrayOfAllValues(phones);

After that phoneNumbers contains every phone number for the current ABPerson.
