Wenn Sie auf Kontakte im Adressbuch (in meiner App) klicken, stürzt das Programm unter iOS 10 Beta ab und funktioniert unter iOS 9 einwandfrei.

Dies ist das Absturzprotokoll

*** 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

Und hier ist der Code zum Öffnen des Adressbuchs in meiner 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);
    }

}

Es stürzt nur in der öffentlichen Beta von iOS 10 ab.
