var query = GameScore.query("score" > 9)

struct ContentView: View {
    
    //: A LiveQuery subscription can be used as a view model in SwiftUI
    @ObservedObject var subscription = query.subscribe!
    var body: some View {
        VStack {
            
            if subscription.subscribed != nil {
                Text("Subscribed to query!")

                Text("Unsubscribed from query!")
            } else if let event = subscription.event {
