Summary:
When using PhotoKit's [PHChange changeDetailsForFetchResult:] on a PHFetchRequest that is ordered by descending creationDate, deletedIndexes and changedIndexes overlap.
Steps to Reproduce:
1. Run the attached sample project (Example app using Photos framework)
2. Select the "All Photos" row.
3. Delete a photo or video from the device.
4. Notice the crash.
Expected Results:
The PHFetchResultChangeDetails' changedIndexes do not overlap the deletedIndexes, preventing exceptions.
Actual Results:
The PHFetchResultChangeDetails' changedIndexes overlap the deletedIndexes, throwing an exception: 'NSInternalInconsistencyException', reason: 'attempt to delete and reload the same index path (<NSIndexPath: 0xc000000000000016> {length = 2, path = 0 - 0})
Version:
iOS 8.0.2
Notes:
The attached sample app is Apple's "Example app using Photos framework"
The only change is that the creationDate sort order has been changed from ascending to descending.
