swift – Mix and Observable Macro iOS 17

I’ve learn the migration information and am nonetheless caught on this one. Within the spirit of the migration information …

OLD

class MyClass: ObservableObject {
    @Revealed var myVariable: String = "Must know"
    
    var subscriptions: Set<AnyCancellable> = []
    
    init() {
        $myVariable.sink { updated_variable in
            //Must function
        }.retailer(in: &subscriptions)
    }
    
}

NEW

@Observable class MyClass {
    var myVariable: String = "Must know"
    
    var subscriptions: Set<AnyCancellable> = []
    
    init() {
        /*
         Error!
         Can't discover '$myVariable' in scope
         */
        $myVariable.sink { updated_variable in
            //Must function
        }.retailer(in: &subscriptions)
    }
    
}

I actually appreciated subscribing to and for that matter assigning to @Revealed variables with mix. Can I nonetheless do that in any method?
