将数据从CollectionVewCell传递到另一个视图控制器

protocol DataTransferDelegate: AnyObject {
    func transferData(data: Any)
}

class CustomCollectionViewCell: UICollectionViewCell {
    weak var delegate: DataTransferDelegate?
    
    func sendDataToViewController() {
        let data = // 获取需要传递的数据
        delegate?.transferData(data: data)
    }
}

class AnotherViewController: UIViewController, DataTransferDelegate {
    // ...
    
    func transferData(data: Any) {
        // 处理传递过来的数据
    }
    
    // ...
}

func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell {
    let cell = collectionView.dequeueReusableCell(withReuseIdentifier: "CustomCell", for: indexPath) as! CustomCollectionViewCell
    cell.delegate = self // 设置代理为当前视图控制器
    return cell
