List contacts with phone numbers - ios

Question

I'd like to fetch (in iOS using Objective-C) only the contacts that have a phone number, but how can I do that? I'm trying to form the predicate as in the code below, but obviously that doesn't work.
contacts = [contactStore unifiedContactsMatchingPredicate:[NSPredicate predicateWithFormat:#"phoneNumbers <> nil"] keysToFetch:KEYS error:nil];
So, what is the correct way of doing this? Thanks for any help!

#import <Contacts/Contacts.h>

use following method and import
#import <AddressBook/AddressBook.h>
#import <Contacts/Contacts.h>
-(void)contactsDetailsFromPhoneContactBook{
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];
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 *fullName;
NSString *firstName;
NSString *lastName;
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];
}
[self.contactsArray addObject:fullName];
NSLog(#"working or not %#",self.contactsArray);
}
}
}
}];
}

Filtering out the contacts that don't have a phone number (or some other property) is not possible. In the docs we read:
CNContact Predicates
Predicates to match contacts. You can only use these predicates
with CNContactStore and CNContactFetchRequest.
predicateForContactsMatchingName: Returns a predicate to find the contacts matching the specified name.
predicateForContactsWithIdentifiers: Returns a predicate to find the contacts matching the specified identifiers.
predicateForContactsInGroupWithIdentifier: Returns a predicate to find the contacts that are members in the specified group.
predicateForContactsInContainerWithIdentifier: Returns a predicate to find the contacts in the specified container.
And additionally:
Compound predicates are not supported.
So, the only way to do the filtering would be to omit adding to the result array the contacts with no phone numbers. That could be done, for example, in the block of the enumerateContactsWithFetchRequest.
