I notice in iOS 14 beta 4, collection views show index views on their trailing edge if the data source implements indexTitlesForCollectionView and indexPathForIndexTitle. But I don't see a way to control any aspect of its appearance. On UITableView this shows up as the sectionIndexColor property.

Does this property exist on UICollectionView somewhere I didn't think to look? Or is it just not there (yet)?

Currently, there isn't a property to explicitly customize the color of the UICollectionView index bar, however it will follow the inherited tintColor from the UICollectionView, so you could customize that if desired. (You can always set the tintColor of cells or other views inside the collection view directly if you want them to use a different color.) Thanks for submitting feedback so we can consider exposing additional API for this!

I'm wondering is this API "indexTitlesForCollectionView" only available in iOS14 above?

That's available since 10.3

Code Block optional func indexTitles(for collectionView: UICollectionView) -> [String]?
