Not sure I'm following you here? Release Notes on a major version of Xcode are a little bit more than just mere notes. In addition, the crash still occurs when numberOfSections is 1 and the numberOfItemsInSection is 0. That was definitely not the case in pervious versions of Xcode.

You are totally correct. With the snipped below it was totally possible for the number of sections to be 0. func numberOfSections(in collectionView: UICollectionView) -> Int {     return answerViewModels.count } However just checking in to see why, if it actually exists, any changes to a detection was not made aware in the release notes.
