View updates triggered without state changes

[slangeder]

Hello 👋

I've finished updating our codebase to @ObservableState. During testing, I noticed performance issues that weren't there in the old version that was using WithViewStore.

After adding _printChanges to SwiftUI views, I could scope down the issue:

1. An action is sent to a store, and the reducer simply returns .none
2. In the console I see (No state changes) from TCA
3. Right after that, _printChanges in my views logs @dependencies changed. for some views.

The view that is getting rerendered simply passes a scoped store forward to a child:

ChildView(store: store.scope(
  state: \.child,
  action: \.child
))

The child store receives the action mentioned above.

Is there anything else that I can try to scope down the issue?

Thank you for your help!

Nevermind. I just found out that the performance issues also occurred before changing the code to @ObservableState with TCA version 1.6.0.
It could be related to updating TCACoordinators.
