RXSwift Update single element
Considering I have a array of items which might be updated on a different view controller and get notified update the change.
How can I update a Observable<[SomeObject]> with a single SomeObject modification so the change will then be propagated to the UITableViewController that presets these items?
P.S.
I can load the whole thing again with some hack, but it's obviously wrong for various reasons.
Thanks.

The short answer is, you can't.
However, if you change your model, there are several ways you can go about doing it. One example is here: https://github.com/dtartaglia/RxMultiCounter
In RxMultiCounter, I populate the tableView with an Observable<[UUID]> and track the changes for each item inside an Observable<[UUID: SomeObject]>. Updating the latter observable doesn't cause the tableView to reload.
