Got this warning: 'Update NavigationAuthority bound path tried to update multiple times per frame.'

Hi, there.

I am trying to add NavigationStackStore onto TabView. But I got this warning whenever I run the app. I have no idea and got stuck trying to find what might be the issue.

Update NavigationAuthority bound path tried to update multiple times per frame.

Here's snippet of my code.

WithViewStore(self.store, observe: \.selectedTab) { viewStore in
    NavigationStackStore(self.store.scope(state: \.path, action: AppFeature.Action.path)) {
        TabView(selection: viewStore.binding(send: AppFeature.Action.selectedTabChanged)) {
        // ...
        }
    }
}

You can see the full code here.

Does anybody have similar experience? how can I fix the warning.

Hi @iRILLLL, unfortunately this is also an issue with vanilla SwiftUI, and I'm not sure of a fix. It might help to move the WithViewStore inside the NavigationStackStore, but that's only a guess.

Hi @mbrandonw thanks for taking your time to replied.

After updating to Xcode 15, the warning disappears (at least for now).

Is happening for me using the last TCA version and Xcode 15.2 with iOS 17. Only once in a while though.

Hi @Alexminator99, can you please provide a sample project that reproduces the behavior? There isn't much anyone can do otherwise.

I will try to make a small project and share it.
