- In almost all cases where you type `@ObservedObject`, you really want `@StateObject`. 
If you need to support iOS 13, use `@State` on parent and pass value into child with `@ObservedObject` to simulate `@StateObject`.
Pass arguments to that model in `onAppear`. Example: https://github.com/ra1028/SwiftUI-Hooks/blob/main/Sources/Hooks/HookScope.swift#L39-L41

```
        .onAppear {
            model.onAppear(userTag: userTag)
        }
        .onDisappear {
            model.onDisappear()

    }

    private typealias Action = (V) -> Void
