The NSIndexSet variants are (soft) deprecated. They will likely be hard deprecated (e.g. produce compiler warnings/errors) in a future release. You should only use the NSIndexPath versions going forward. Using a mix of the two variants of API is not supported. To bind NSCollectionView -selectionIndexPaths to NSArrayController’s -selectionIndexes you will have to set up the observing glue to translate NSArrayController -selectionIndexes changes into a set of NSIndexPaths and call NSCollectionView -selectionIndexPaths, and vise versa. Hope that helps. Good luck.
