App crashes in iOS 13 when pushing ABPersonViewController

Question

Till iOS 12 code is working fine. But the below code is crashing the application on iOS13.

NOTE: I do not want to upgrade to Contacts framework right now.

Sharing my code below:

ABPersonViewController *vc = [[ABPersonViewController alloc] init];
vc.displayedPerson = person;
vc.addressBook = parser.addressbook;
vc.allowsEditing = YES;
vc.personViewDelegate = self;
[self.navigationController pushViewController:vc animated:YES];

When pushing, app crashes only on iOS 13. sharing below crash stack:

*** Terminating app due to uncaught exception 'CNPropertyNotFetchedException', reason: 'Contact 0x7fb020d2bc70 is missing some of the required key descriptors: (
    "<CNAggregateKeyDescriptor: 0x600003176be0: kind=+[CNContactContentViewController descriptorForRequiredKeys]>"

I'm using AddressBook framework. Please help me get through this. Thanks

Answer 1

AddressBook and AddressBookUI Is deprecated

Better is to shift to

 @import Contacts; 
 @import ContactsUI;


-(void)fetchAllContacts:(void(^)(BOOL success, NSError * _Nullable error))completion
{
    self.contactArray = [[NSMutableArray alloc] init];

    CNContactStore *store = [[CNContactStore alloc] init];
    [store requestAccessForEntityType:CNEntityTypeContacts completionHandler:^(BOOL granted, NSError * _Nullable error) {

        if (success)
        {
            NSArray *keys = @[CNContactNamePrefixKey, CNContactFamilyNameKey, CNContactGivenNameKey,
                              CNContactPhoneNumbersKey, CNContactImageDataKey, CNContactEmailAddressesKey];

            NSString *containerId = store.defaultContainerIdentifier;
            NSPredicate *predicate = [CNContact predicateForContactsInContainerWithIdentifier:containerId];
            NSError *error;
            NSArray *cnContacts = [store unifiedContactsMatchingPredicate:predicate keysToFetch:keys error:&error];

            if (error)
            {
                NSLog(@"ERROR IN FETCHING: %@", error.description);
            }
            else
            {
                for (CNContact *contact in cnContacts)
