Проблема с действием ActionSheet открыть новый вид (SwiftUI)

Я пытаюсь написать базовые c приложения, используя разные представления. На главном экране есть кнопка, которая должна открыть другой вид. представление находится в другом быстродействующем файле, называемом мышлением. Невозможно преобразовать значение типа 'I'mtsView ()' в тип результата закрытия 'ActionSheet'

Снимок экрана ошибки

Это файл swift, содержащий мысленный обзор, который я хочу видеть в новом листе действий: 

struct ThoughtsView: View {

    var thoughtStore: ThoughtStore


    var body: some View {



        List(thoughtStore.thoughts, id: \.id) {thought in
            Text(thought.thoughtName)
        }
    }
}

struct ThoughtsView_Previews: PreviewProvider {
    static var previews: some View {
        ThoughtsView( thoughtStore: ThoughtStore() )
    }
}

В случае, если здесь есть ошибка, код sceneDelegate: 

import UIKit
import SwiftUI

class SceneDelegate: UIResponder, UIWindowSceneDelegate {

    var window: UIWindow?


    func scene(_ scene: UIScene, willConnectTo _: UISceneSession, options _: UIScene.ConnectionOptions) {
        // Use this method to optionally configure and attach the UIWindow `window` to the provided UIWindowScene `scene`.
        // If using a storyboard, the `window` property will automatically be initialized and attached to the scene.
        // This delegate does not imply the connecting scene or session are new (see `application:configurationForConnectingSceneSession` instead).



        // Use a UIHostingController as window root view controller.
        if let windowScene = scene as? UIWindowScene {
            let window = UIWindow(windowScene: windowScene)

            // Create the SwiftUI view that provides the window contents.
                   let contentView = NewThoughtView()

            window.rootViewController = UIHostingController(rootView: contentView)
            self.window = window
            window.makeKeyAndVisible()
        }
    }

    func sceneDidDisconnect(_ scene: UIScene) {
        // Called as the scene is being released by the system.
        // This occurs shortly after the scene enters the background, or when its session is discarded.
        // Release any resources associated with this scene that can be re-created the next time the scene connects.
        // The scene may re-connect later, as its session was not neccessarily discarded (see `application:didDiscardSceneSessions` instead).
    }

    func sceneDidBecomeActive(_ scene: UIScene) {
        // Called when the scene has moved from an inactive state to an active state.
        // Use this method to restart any tasks that were paused (or not yet started) when the scene was inactive.
    }

    func sceneWillResignActive(_ scene: UIScene) {
        // Called when the scene will move from an active state to an inactive state.
        // This may occur due to temporary interruptions (ex. an incoming phone call).
    }

    func sceneWillEnterForeground(_ scene: UIScene) {
        // Called as the scene transitions from the background to the foreground.
        // Use this method to undo the changes made on entering the background.
    }

    func sceneDidEnterBackground(_ scene: UIScene) {
        // Called as the scene transitions from the foreground to the background.
        // Use this method to save data, release shared resources, and store enough scene-specific state information
        // to restore the scene back to its current state.
    }


}

Что я делаю не так? Заранее спасибо ...

Я просто изменяю ваш код, при нажатии на кнопку открывается ваш вид. Я полагаю, вы пытаетесь это сделать. 

struct ContentView: View {

@State var thought = ""
@State var modalIsPresented = false

var body: some View {
    NavigationView {
        VStack {
            Spacer()
            TextField("Type your thought...", text: $thought)
            Spacer()
            Button(action: /*@START_MENU_TOKEN@*/{}/*@END_MENU_TOKEN@*/) {
                Text("Ok")
            }
            Spacer()
            Spacer()

            // Thought Library Button

            Button(action: {self.modalIsPresented = true}) {
                Text("Review your thoughts")
            }.sheet(isPresented: $modalIsPresented, content: {
                 ThoughtsView(thoughtStore: ThoughtStore())
            })
        }
        .navigationBarTitle(Text("Skillful"))
    }
    /*.actionSheet(isPresented: $modalIsPresented) {

        ThoughtsView()
    }*/
}

}

...
