Important

SwiftUI has issues in the case in a View has existed multi alert

This example suggests the way to init alert on root view instead of creating multi alert on each View

Scaleable in case iOS 18, we also moving it to Dependency Injection to control same with DDD

@main
struct AlertApp: App {
    @StateObject var alertController = AlertAppState()
    var body: some Scene {
        WindowGroup {
            ContentView()
                .onShowAlert(with: $alertController.alert)
        }
        .environmentObject(alertController)
    }
}

extension View {
    fileprivate func onShowAlert(with alert: Binding<AlertObject?>) -> some View {
        modifier(SingleAlertViewModifier(alert: alert))
    }
}

struct ContentView: View {
    @EnvironmentObject var alertAppState: AlertAppState

    var body: some View {
        VStack {
            Image(systemName: "globe")
                .imageScale(.large)
                .foregroundStyle(.tint)
            Text("Hello, world!")
            Button {
                alertAppState.setShowAlert(
                    AlertObject(
                        title: "Example",
                        buttonTitle: "OK",
                        buttonCancelTitle: "Cancel",
                        message: "Example",
                        action: {
                            print("OKK")
                        },
                        actionCancel: {
                            print("cancel")
                        }
                    )
                )
            } label: {
                Text("Test")
            }

        }
        .padding()
    }
}
