Contact Address book crash on iOS 10 beta

Question

When click on any contacts in address book (inside my app) it's crashing on iOS 10 beta and working fine on iOS 9 versions;

This is the crash log

*** Terminating app due to uncaught exception 'CNPropertyNotFetchedException', reason: 'A property was not requested when contact was fetched.'
*** First throw call stack:
(0x1cf11a07 0x1c62af63 0x1cf1194d 0x246f0f4f 0x246c6a71 0x1ce355eb 0x1ce2e19b 0x246c69cf 0x246c6883 0x25e4a375 0x2538f283 0x254204ef 0x25420bb1 0xe9da97 0xe9da83 0xea2321 0x1cecf18f 0x1cecd477 0x1ce1e6bd 0x1ce1e549 0x1e54ebfd 0x21f961e3 0x21f90947 0x966c9 0x1ca9e507)
libc++abi.dylib: terminating with uncaught exception of type NSException

And here is the code to open address book inside my app:

-(void)showContactPicker {
__weak RecieverSelectorViewController *weakSelf = self;
    ABPeoplePickerNavigationController* picker = [[ABPeoplePickerNavigationController alloc] init];
    picker.peoplePickerDelegate = self;
    picker.modalPresentationStyle = UIModalPresentationFullScreen;
    picker.modalTransitionStyle = UIModalPresentationPopover;
    [self presentViewController:picker
                       animated:YES
                     completion:^{
                         [weakSelf hideLoadingAnimation];

                         // animation to show view controller has completed.
                     }];
}



- (void)peoplePickerNavigationController:(ABPeoplePickerNavigationController *)peoplePicker didSelectPerson:(ABRecordRef)person property:(ABPropertyID)property identifier:(ABMultiValueIdentifier)identifier {
    [self setSelectedPerson:person];
}

- (void)peoplePickerNavigationController:(ABPeoplePickerNavigationController*)peoplePicker didSelectPerson:(ABRecordRef)person {
    [self setSelectedPerson:person];
}

-(void)setSelectedPerson:(ABRecordRef)person {


    NSString *contactName = CFBridgingRelease(ABRecordCopyCompositeName(person));

    ABMultiValueRef phoneRecord = ABRecordCopyValue(person, kABPersonPhoneProperty);
    CFStringRef phoneNumber = ABMultiValueCopyValueAtIndex(phoneRecord, 0);

    self.isSenderReciever = NO;

    NSString *phone = [PorterUtils
                       extraLast10DigitsFromDigitString:[PorterUtils
                                                         extractNumberFromText:(__bridge_transfer NSString *)phoneNumber]];




    //Handling Social Media Contacts - Crash

    if(contactName.length>0 && phone.length>0){

      [self setRecieverName:contactName
                   number:phone];
       CFRelease(phoneRecord);
    }

}

It's crashing only on iOS 10 public beta.

Answer 1

First add NSContactsUsageDescription in info.plist and then present the controller in AB request access block like .

ABAddressBookRequestAccessWithCompletion(contactPicker, { success, error in
  if success {
    self.presentViewController(self.contactPicker, animated: true, completion: nil)
  }
})

Answer 2

check whether you have provided valid keys like

@[CNContactFamilyNameKey, CNContactGivenNameKey, CNContactPhoneNumbersKey, CNContactEmailAddressesKey]

when they are requesting from CNContact object.

ex: if you need to call contact.emailAddresses it must be provided from (CNContactEmailAddressesKey) array.
