Crash on cell Getting

@chelemen-razvan @SpectralDragon Please help !

[SpectralDragon]

Not enough information to solve your problem. Seem like you don't implement CardCollectionViewCell for your cells.

like @SpectralDragon I added the following code to my controller to run，it's ok

extension AViewController: CardsViewController {

}

but , please the issues ... i don't understand how to fix it 

this is my BViewConrollerCode and [Video](http://xuanci.tw/kmc/issues/ErrorSample.mp4)

```swift
extension BViewController: CardDetailViewController {

    var cardContentView: UIView {
        return collectionView
    }

    var scrollView: UIScrollView? {
        return collectionView
    }

}
