Number of minimal stages that can perform batch updates with no crashes. about differencekit HOT 4 CLOSED

I will also be very happy to see a method to return a guaranteed 1-staged changeset, since if I call performBatchUpdates multi times the animation looks broken.

Sorry for my late reply.
Regardless of the number of sections, reload with a 1-staged changeset will cause a crash in several cases.
I think crashes are inevitable in many other libraries.
As far as I know, the libraries that can provide stable behavior in every case are DifferenceKit, RxDataSources, and IGListKit.
IGListKit avoids crashes by decomposing reloadItems into deletes and inserts. DifferenceKit and RxDataSources are using the same approach.
This means that it's impossible to prevent crashes and glitches in complex diff animations at the same time, due to the specification of UIKit.

@ra1028 Thank you for your reply. Are there any known combinations to crash a view with single section?

from differencekit.

UIKit is a black-boxed framework, so I don't know all the specs, but the most typical case is when it takes move and update at the same time.
Even similar combinations may or may not crash, depending on the other conditions.
