Support animated data reloading

[LinusGeffarth]

I'd love to be able to update the collectionView's data on the go. I found this code does the job:

let range = Range(uncheckedBounds: (0, collectionView.numberOfSections))
let indexSet = IndexSet(integersIn: range)
collectionView.reloadSections(indexSet)

However, running this, makes the app crash at line 112 because of an unexpected nil:

override open func layoutAttributesForItem(at indexPath: IndexPath) -> UICollectionViewLayoutAttributes? {
    return dynamicAnimator.layoutAttributesForCell(at: indexPath)!
}

I tried removing the ! to prevent the force-unwrapping of a nil variable, but that resulted in a generic terminating with uncaught exception of type NSException.

Any way we can update the data at runtime while viewing the collectionView?
I'm thinking of some cool animation: the cell that's to be removed scales down, then the cells below move up smoothly w/ a .easeOut curve. Would be awesome. Thanks!

@AppliKey, any chance for you to implement this? Thanks!
