I've tested the same project with Xcode 8 beta 2 and I can't reproduce the crash. Great job. 👍

Summary:
I am using your method called photoLibraryDidChange in my iOS 9 app. This makes it crash all the time when Photos Library is updated. Because your sample is iOS 10 only, I had to refactor it. Code attached.

Steps to Reproduce:
1. Delete one photo in Simulator
2. Open sample app

Expected Results:
New photo appear

Actual Results:
 I have crash message: "attempt to delete and reload the same index path"

Version:
Example app using Photos framework

Notes:
I am attaching my app project so you can run it yourself. My app displays screenshots from Screenshots album in a collection view. Press command + S to make a screenshot and drag it into Simulator. It should appear in the Altershot.

I am attaching my refactored iOS 9 sample code. Related pre iOS 10 question http://stackoverflow.com/questions/29337765/crash-attempt-to-delete-and-reload-the-same-index-path#29370012

I will keep you updated. I will try to run your code as it is in iOS 10. Maybe this is bug in UIKit which you fixed in iOS 10.

Configuration:
Xcode 7.3.1 
iOS 9 iPhone 5s Simulator
