swift - 将变量从 App 文件 SwiftUI 2 传递到 ContentView？

Question

所以现在我的 ContentView 看起来像这样：

struct ContentView: View {
    @ObservedObject var appState: AppState
    @ObservedObject var lManager: LManager
    @ObservedObject var functionMaster: functions
    @ObservedObject var sManager: SManager
    init() {
        let appStateStarter = AppState()
        appState = appStateStarter
        let sManagerStarter = SManager(appState: appStateStarter)
        let functionMasterStarter = functions(appState: appStateStarter)
        let lManagerStarter = LManager(appState: appStateStarter, functionMaster: functionMasterStarter, sManager: sManagerStarter)
        sManager = sManagerStarter
        lManager = lManagerStarter
        functionMaster = functionMasterStarter
    }
}

我的应用程序文件如下所示：

@main
struct Test_1App: App {
    var body: some Scene {
        WindowGroup {
            ContentView()
            .onOpenURL { url in
                //here I need to have access to the functionMaster I defined in ContentView, and by extension the AppState inside of it. How can I do that?
            }
        }
    }
}

我想我必须为 ContentView 重新定义我的 init() 但老实说，我非常不确定如何正确地构造它，以便正确保留所有依赖项。任何帮助将非常感激！
