//remove/clear all items from NSCollectionView

 for (int i = 0; i < [[arrayController arrangedObjects] count]; i++) {
        [arrayController removeObjectAtArrangedObjectIndex:i];
        i--;
    }

Try this

NSIndexSet* selectedIndexSet = [_lablesCollectionView selectionIndexes];
NSUInteger index = [selectedIndexSet firstIndex] ;
NSLog(@"index is %d", index);
[lablesArray removeObjectsAtArrangedObjectIndexes:selectedIndexSet];

Hope it helps.
