Hi, I'm trying to implement a collection view with the diffable data source. I have some optional advertisment which I would like to put in a separate section of the collection view (for specific layouting etc.). My sections look like this:
enum Section: Int, CaseIterable {
case topSection
case midSection
case advertismentSection
case bottomSection
}
The height of the item in the advertismentSection
is defined like this:
let heightDimension = NSCollectionLayoutDimension.estimated(200)
this heightDimension
is then used for the group height etc.
This works fine when I add items to the advertismentSection
, however, when it's empty, I would assume it should have height of 0, but it's not the case, it's 200
regardless if it's empty or not. When I try to make the height 0, I get a warning that it's invalid. Another approach I tried is to simply not add this advertismentSection
to the snapshot when I have nothing to show, but this crashes the app because the number of sections in the snapshot needs to be the same as defined in your Section
enum.
How should I solve this problem?
