将变量从 App 文件 SwiftUI 2 传递到 ContentView？

问题描述

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建它以便正确保留所有依赖项。任何帮助将不胜感激！
