The model needs to be updated right after the animation is complete:

@IBAction func onRemoveClick(sender: AnyObject?) {
    let selection = listController.selectionIndexes
    NSAnimationContext.runAnimationGroup({
        context in
        self.tableView.removeRowsAtIndexes(selection, withAnimation: .EffectFade | .SlideUp)
    }, completionHandler: {
        self.listController.removeObjectsAtArrangedObjectIndexes(selection)
    })
}
