import UIKit 
import ContactsUI 

class ViewController: UIViewController ,CNContactPickerDelegate { 
    let contactStore = CNContactStore() 
    let amount = 200 
    //var selectedContact:CNContact = CNContact() 
    //var results:[CNContact] = [] 
    var res:CNContact = CNContact() 
    var a = [String]() 
    override func viewDidLoad() { 
     super.viewDidLoad() 
     perform(#selector(contactPicker(_:didSelect:)), with: nil, afterDelay: 0)

      } 
    } 


    func contactPickerDidCancel(_ picker: CNContactPickerViewController) {

Answer 1

ありがとうございます。プログラム内の1行を変更するだけです。これは、選択されたすべての連絡先を配列に表示します。

func contactPicker(_ picker: CNContactPickerViewController, didSelect contacts: [CNContact]) { 
     contacts.forEach { contact in 
      a+= [contact.givenName]//I changed at this place 
} 
print(a)

#import <Contacts/Contacts.h> 

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 { 


        NSLog(@"Contact Array %@",cnContacts.description); 
       } 
      } 
     }];
