CollectionView 선택이 작동하지 않습니다.

Question

UICollectionView에서 셀을 선택하려고하는데 작동하지 않습니다. 많은 자습서를 보았지만 아무도 도움이되지 못했습니다. 나는 그들과 정확히 똑같이했으나 광산은 효과가 없습니다. 누군가가 나를 도울 수 있기를 바랍니다!

CollectionView 코드를 만듭니다

func createCollectionView() { 
    let layout = UICollectionViewFlowLayout() 
    layout.itemSize = CGSize(width: view.frame.size.width/2.75, height: view.frame.size.width/2.75) 
    layout.minimumLineSpacing = 10 
    layout.scrollDirection = .vertical 

    photoCollectionView = UICollectionView(frame: CGRect(x: 0, y: 0, width: view.frame.size.width/1.2, height: view.frame.size.height - biographyLabel.center.y - 75 - 
     navigationController!.navigationBar.frame.size.height), collectionViewLayout: layout) 
    photoCollectionView.backgroundColor = UIColor.white 
    photoCollectionView.showsVerticalScrollIndicator = false 
    photoCollectionView.showsHorizontalScrollIndicator = false 
    photoCollectionView.allowsSelection = true 
    photoCollectionView.delegate = self 
    photoCollectionView.dataSource = self 
    photoCollectionView.register(PhotosCollectionViewCell.self, forCellWithReuseIdentifier: "photoCell") 
    photoCollectionView.center = CGPoint(x: view.frame.size.width/2, y: view.frame.size.height - (photoCollectionView.frame.size.height/2) - navigationController!.navigationBar.frame.size.height) 

    view.addSubview(photoCollectionView) 
} 

선택 코드 : 돕는

func collectionView(_ collectionView: UICollectionView, didSelectItemAt indexPath: IndexPath) { 
    print("test") 
} 

감사합니다!

UPDATE :

휴대 코드 만들기 :

내가 createCollectionView 기능에 view.gestureRecognizers?.removeAll()을 추가하여 고정합니다.
