Swift 프록시 전송 및 클로즈업 전송

A-B 그리고 B는 값을 A에 전달합니다. A는 CollectionView B가 A의 개수를 바꾸는oc에서 프로토콜에 @objc A 코드를 추가할 수 없으면 import UIKit class ViewController: UIViewController, UICollection View Delegate, UICollection View DataSource,SecondVCDelegate { @IBOutlet weak var collectionView : UICollectionView? var count = 5; override func viewDidLoad() { super.viewDidLoad()//Do any additional setup after loading the view, typically from a nib.
