ForEach<_StoreCollection<String, State, Action>, ObjectIdentifier, SingleTaskView>: the ID ObjectIdentifier(0x0000600003fe8b40) occurs multiple times within the collection, this will give undefined results! about swift-composable-architecture HOT 2 CLOSED

I logged state.todos and there were no identical ids.

@zhangpeibj01 In the upgrade guide we note that the 1:1 migration requires you to explicitly select the id from store state, otherwise ForEach will take the child store's object identifier:

https://pointfreeco.github.io/swift-composable-architecture/main/documentation/composablearchitecture/migratingto1.7#Replacing-ForEachStore-with-ForEach

So you should update your code for a true comparison:

 ForEach(
-  store.scope(state: \.tasks, action: \.tasks)
+  store.scope(state: \.tasks, action: \.tasks), id: \.state.id
 ) { store in
   SingleTaskView(store: store)
 }

I'm going to convert this to a discussion since it doesn't appear to be a bug with the library, but if you do think you've encountered a bug, please provide a sample project that reproduces the issue. Without it we won't be able to troubleshoot the problem.
