How to Use Swift @Bindable with Observable Protocol

We can conform a protocol to Observation.Observable by conforming it to AnyObject and Observable.

This won't automatically make all of it's implementations observable, but makes it possible to use things like @Bindable by satisfying the compiler.

@MainActor
protocol StoreProtocol: AnyObject, Observable {}

In our implementation we need to explicitly use the @Observation protocol to add observation to our class. Without this our code will compile, but observation won't work.

@Observable
final class MyStore: StoreProtocol {}

We then can use the protocol via generics in our view and use the @Bindable keyword.

struct StoreView<Store: StoreProtocol>: View {

    @Bindable var store: Store

}

If we use any StoreProtocol instead of a generic we will get the following compiler error:

'init(wrappedValue:)' is unavailable: The wrapped value must be an object that conforms to Observable.
