List breaks re-render of view with new observing

[jiledaa]

Hi. I've migrated my app up to version 1.8 using new observing of the store. Everything seems to work fine except on iOS 16 when I add new element to the List component on another screen where the List exists and then show the list. The new element is not there, only after relaunching the app or when the list is long enough to scroll down and back up, the new added element seems to appear on top of the list correctly.

List { ForEach(store.scope(state: \.entries, action: \.entries), id: \.state.id) { store in Feature(store: store) } }

• Adding WithPerceptionTracking inside List, neither inside ForEach, does not help. I dont have any purple warnings about perception in runtime anyway.
• When I replace List with ScrollView for example, it updates correctly.
• When I'm adding new element to List on the same screen with the list, the re-rendering is also fine, it happens only when the List is not presented at time of updating.

Has anyone similar experience?

Hi @jiledaa, can you please reproduce the problem in a minimal project and share it? That is the only way for anyone to help.

"Feature1" represents "MainFeature" and still uses WithViewStore, which somehow forks fine and updates view properly in this provided code. Getting rid of VithViewStore is still not completely done in my project.

Is this code you provided actually demonstrating the problem? If so, what is the problem?

Also, it definitely is not right to mix WithPerceptionTracking and WithViewStore. And further, this code does have lots of purple warnings letting you know that something definitely is not right.

I know, I tried to reproduce the actual state of the app as much as possible. I might miss something because I'm not getting any purple warnings in my app, but still List is not updated properly. In this provided code, I'm getting warnings but updating works.

Even full replacement of WithViewStore from the app did not fixed the issue. I've fixed it temporarily by adding VStack inside the ForEach of the List.
