CollectionScreen crashes after reloading data

[nickyhajal]

I have a CollectionScreen that I'm using to display dates. If I change the dates on the collection and call reload_data, I get the following error:

'NSInternalInconsistencyException', reason: 'UICollectionView received layout attributes for a cell with an index path that does not exist: <NSIndexPath: 0xc000000000e00016> {length = 2, path = 0 - 7}'

The web is full of reports like the following:

However, calling this.collectionViewLayout.invalidateLayout or this.collectionView.collectionViewLayout.invalidateLayout seems to have no effect.

The error is exactly the same no matter what data I update with (even an empty array).

I've been trying to resolve this for about 24 hours with no progress so I wanted to check in to see if anyone here has thoughts on how to get data reloading properly.

Thanks!

Hey @nickyhajal I seem to remember this happening to me, but it was several years ago, so I don't remember what project or how I solved it.
