NsMutable Array not adding object iOS - ios

Question

I am accessing contact from user phone. Everything is working perfectly but when I add it into the NSMutableArray then nothing is entered. In breakpoint when I click on array its showing 0X16bed870. My code is as follow.
-(void)mycontact
{
NSMutableArray * contactNumbersArray = [[NSMutableArray alloc] init];
CNAuthorizationStatus status = [CNContactStore authorizationStatusForEntityType:CNEntityTypeContacts];
if (status == CNAuthorizationStatusDenied || status == CNAuthorizationStatusRestricted)
{
UIAlertController *alert = [UIAlertController alertControllerWithTitle:nil message:#"This app previously was refused permissions to contacts; Please go to settings and grant permission to this app so it can use contacts" preferredStyle:UIAlertControllerStyleAlert];
[alert addAction:[UIAlertAction actionWithTitle:#"OK" style:UIAlertActionStyleDefault handler:nil]];
[self presentViewController:alert animated:TRUE completion:nil];
return;
}
CNContactStore *store = [[CNContactStore alloc] init];
[store requestAccessForEntityType:CNEntityTypeContacts completionHandler:^(BOOL granted, NSError * _Nullable error) {
if (granted == YES) {
//keys with fetching properties
NSArray *keys = #[CNContactFamilyNameKey, CNContactGivenNameKey, CNContactPhoneNumbersKey, CNContactImageDataKey];
NSString *containerId = store.defaultContainerIdentifier;
NSPredicate *predicate = [CNContact predicateForContactsInContainerWithIdentifier:containerId];
NSError *error;
NSArray *cnContacts = [store unifiedContactsMatchingPredicate:predicate keysToFetch:keys error:&error];
if (error) {
NSLog(#"error fetching contacts %#", error);
} else {
NSString *phone;
NSString *fullName;
NSString *firstName;
NSString *lastName;
UIImage *profileImage;
for (CNContact *contact in cnContacts) {
// copy data to my custom Contacts class.
firstName = contact.givenName;
lastName = contact.familyName;
if (lastName == nil) {
fullName=[NSString stringWithFormat:#"%#",firstName];
} else if (firstName == nil) {
fullName=[NSString stringWithFormat:#"%#",lastName];
} else {
fullName=[NSString stringWithFormat:#"%# %#",firstName,lastName];
}
UIImage *image = [UIImage imageWithData:contact.imageData];
if (image != nil) {
profileImage = image;
}else{
profileImage = [UIImage imageNamed:#"person-icon.png"];
}
for (CNLabeledValue *label in contact.phoneNumbers) {
phone = [label.value stringValue];
if ([phone length] > 0) {
[contactNumbersArray addObject:phone];
}
}
NSDictionary* personDict = [[NSDictionary alloc] initWithObjectsAndKeys: fullName,#"fullName",profileImage,#"userImage",phone,#"PhoneNumbers", nil];
}
dispatch_async(dispatch_get_main_queue(), ^{
for(int j=0;j<[contactNumbersArray count];j++)
{
NSString *newString = [[contactNumbersArray[j] componentsSeparatedByCharactersInSet:
[[NSCharacterSet decimalDigitCharacterSet] invertedSet]]
componentsJoinedByString:#""];
contactNumbersArray[j]=newString;
}
});
}
}
}];
}
