Can I use EnvironmentStateObject with the @Observable macro?

[GregoryZeng]

Hi,
I am a beginner in SwiftUI and GRDB so correct me if I am wrong 😂
The view models from the docs and examples use the Combine-style ObservableObject.
https://swiftpackageindex.com/groue/grdbquery/0.9.0/documentation/grdbquery/mvvm
https://github.com/groue/GRDBQuery/tree/main/Documentation/MVVMDemo

I wonder if the @Observable macro can also apply to the view model with GRDB, removing the @Published and the ObservableObject?

Thanks.

Hello, @GregoryZeng,

ObservableObject requires an ObservableObject, and is not able to deal with observable classes decorated with @Observable.

I don't have any ready-made option for instantiating @Observable instances from the environment.

In your own explorations, make sure you carefully read the Store observable objects chapter of the @State documentation.

Thanks for your prompt answer.

ObservableObject requires an ObservableObject

You mean EnvironmentStateObject requires an ObservableObject?

OK, I thought that ObservableObject can be migrated to @Observable directly ...

Yes, thank you for fixing my typo :-)
