ABRecordCopyValue crash with SIGSEGV

I am trying to get contacts list like this:

CFErrorRef *error = nil;
ABAddressBookRef addressBook = nil;

__block BOOL accessGranted = NO;

if (ABAddressBookGetAuthorizationStatus() == kABAuthorizationStatusNotDetermined ||
    ABAddressBookGetAuthorizationStatus() == kABAuthorizationStatusAuthorized) {

    addressBook = ABAddressBookCreateWithOptions(NULL, error);
    dispatch_semaphore_t sema = dispatch_semaphore_create(0);
    ABAddressBookRequestAccessWithCompletion(addressBook, ^(bool granted, CFErrorRef error) {
        accessGranted = granted;
        dispatch_semaphore_signal(sema);
    });
    dispatch_semaphore_wait(sema, DISPATCH_TIME_FOREVER);
}
else if (ABAddressBookGetAuthorizationStatus() == kABAuthorizationStatusDenied ||
         ABAddressBookGetAuthorizationStatus() == kABAuthorizationStatusRestricted) {
    return nil;
}

if (!accessGranted) {

    if (addressBook) CFRelease(addressBook);
    return nil;
}

CFIndex nPeople = ABAddressBookGetPersonCount(addressBook);

if (nPeople <= 0) {
    CFRelease(addressBook);
    return nil;
}

ABRecordRef source = ABAddressBookCopyDefaultSource(addressBook);
CFArrayRef allPeople = ABAddressBookCopyArrayOfAllPeopleInSourceWithSortOrdering(addressBook, source, kABPersonSortByFirstName);

if (!allPeople) return nil;

NSMutableArray *contactsArray = [NSMutableArray arrayWithCapacity:nPeople];

for (CFIndex i = 0; i < nPeople; ++i) {

    ABRecordRef person = CFArrayGetValueAtIndex(allPeople, i);

    if (!person) continue;

    ContactData *contact = [ContactData new];
    contact.firstName = (__bridge_transfer NSString*)ABRecordCopyValue(person, kABPersonFirstNameProperty);

It is working on my iPhone 5s and simulator, but the build is crashing on the tester iPod device on the line with SIGSEGV:

   contact.firstName = (__bridge_transfer NSString*)ABRecordCopyValue(person, kABPersonFirstNameProperty);

Here is the stack:

3 AppSupport 0x34129a04 CPRecordCopyProperty 4 AppSupport 0x34129a04 CPRecordCopyProperty 5 AddressBook 0x2fd6ad22 ABRecordCopyValueUnfiltered 6 AddressBook 0x2fd6abc6 ABRecordCopyValue

I had the same error, the problem is that: 

CFArrayRef allPeople = ABAddressBookCopyArrayOfAllPeopleInSourceWithSortOrdering(addressBook, source, kABPersonSortByFirstName);

and

CFIndex nPeople = ABAddressBookGetPersonCount(addressBook);

are giving a different number of contacts (so in your case nPeople is probably bigger than allPeople, which causes the crash). "source" doesn't seem to be giving all the contacts in the address book. Changing it to nil solved it for me. Also, to be sure I would do: nPeople = CFArrayGetCount(allPeople);

The solution is very well explained by Jokinryou Tsui in this post: ABAddressBookCopyArrayOfAllPeople and ABAddressBookGetPersonCount return different sizes

(This is my first post, so I'm not sure if I broke any rules or followed the right procedure. I hope the answer helps!)
