Dynamically resizing UICollectionViewCell while editing content

I'm kind of stuck with a problem here. So, I've got a UICollectionView with a textView inside. The problem is, that I need to change the collectionViewCell's height and therefor it's y-position in the collectionView if I'm adding a line of text to the textView. Unfortunately, everything I tried doesn't work. Here's what it looks like:

(I'm not allowed to post full size screenshots)

Ss

Green = collectionViewBackground, black = cell's background

Does somebody know how to make the green disappear?

Make your viewcontroller implements UICollectionViewDelegateFlowLayout and override the sizeForItemAt function

func collectionView(_ collectionView: UICollectionView, layout collectionViewLayout: UICollectionViewLayout, sizeForItemAt indexPath: IndexPath) -> CGSize {
    let data: String = list[indexPath.row] //Your data for specific index
    let size = data.size(attributes: nil)
    return size
}

This should help you resolve your problem and don't forget to set collectionview.delegate = self //Your view Controller
