This question is very old but a simple way to do it is to just set a delay that covers the time your view is animating and disabling the animation while you update the view...usually a delete or insert takes about .35 seconds so just do:

 delay(0.35){
            UIView.performWithoutAnimation{
            self.collectionView.reloadSections(NSIndexSet(index: 1))  
            }
