Diff for sectioned table views and collection views

[larryonoff]

Current API only supports diffs of two arrays. But iOS table views and collection views often needs support for sections. It can be represented as array of arrays.

Is it possible to add support for diff of array of arrays?

@larryonoff Hi, it does not work (as of my implementation of Wagner Fischer and Heckel algorithms) for array of arrays yet. I just made some changes to calculate IndexPath for a specific section in this release https://github.com/onmyway133/DeepDiff/releases/tag/1.1.1 which partly solves the problem

@larryonoff Hi, I'm doing the diff for sections now to serve this https://github.com/hyperoslo/Upstream. Will keep you posted

Hey @onmyway133, thanks for writing DeepDiff :)
Is there an update on diffing sections without using Upstream? I'm looking forward to add it as a diffing engine in my table/collection manager, let me know!

@larryonoff @onmyway133 @riteshhgupta Hi, I'm working on ReactComponentKit. It uses DeepDiff to diff for UICollectionView or UITableView. Thanks, @onmyway133. Also, It uses Redux and Component concept like React. There is some example of ReactComponentKit. I want to it helps you. :)

@riteshhgupta Hi, I'm quite busy atm so not sure if I can add support for section now
@skyfe79 Looks like a nice combo, I like it a lot. Just added it to my curation https://github.com/onmyway133/fantastic-ios-architecture. Also for layout, have you considered this https://github.com/onmyway133/Anchors 😉

@onmyway133 Really thanks for the listing! Anchors is awesome to me. I'll use it and considering remove SnapKit. Anchors is great! :)

@riteshhgupta I found this issue having the same feature request, but ended up using https://github.com/tonyarnold/Differ instead. It has sectioned diffing out-of-the-box, I recommend checking it out.
