I appreciate your help.
I am using UIHostingController.
SceneDelegate.swift
import UIKit
import SwiftUI
import AuthenticationServices
var globalPresentationAnchor: ASPresentationAnchor? = nil
class SceneDelegate: UIResponder, UIWindowSceneDelegate {
@ObservedObject(initialValue: OrientationModel()) var orientationModel: OrientationModel
var window: UIWindow?
func scene(_ scene: UIScene, willConnectTo session: UISceneSession, options connectionOptions: 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).
// Get the managed object context from the shared persistent container.
let context = (UIApplication.shared.delegate as! AppDelegate).persistentContainer.viewContext
// Create the SwiftUI view and set the context as the value for the managedObjectContext environment keyPath.
// Add `@Environment(\.managedObjectContext)` in the views that will need the context.
let contentView = ContentView().environment(\.managedObjectContext, context)
// Use a UIHostingController as window root view controller.
if let windowScene = scene as? UIWindowScene {
let window = UIWindow(windowScene: windowScene)
window.rootViewController = UIHostingController(rootView: contentView.environmentObject(orientationModel))
self.window = window
window.makeKeyAndVisible()
}
globalPresentationAnchor = window
}
func sceneDidBecomeActive(_ scene: UIScene) {
// Called when the scene has moved from an inactive state to an active state.
print("SceneDelegate - active")
}
func sceneDidEnterBackground(_ scene: UIScene) {
print("SceneDelegate - background")
}
func sceneDidDisconnect(_ scene: UIScene) {
print("SceneDelegate - inactive")
}
func windowScene(_ windowScene: UIWindowScene, didUpdate previousCoordinateSpace: UICoordinateSpace, interfaceOrientation previousInterfaceOrientation: UIInterfaceOrientation, traitCollection previousTraitCollection: UITraitCollection) {
orientationModel.orientation = windowScene.interfaceOrientation
}
}
final class OrientationModel: ObservableObject {
@Published var orientation: UIInterfaceOrientation = .unknown
}
AppDelegate.swift
import UIKit
import CoreData
@UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate {
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
// Override point for customization after application launch.
return true
}
// MARK: UISceneSession Lifecycle
func application(_ application: UIApplication, configurationForConnecting connectingSceneSession: UISceneSession, options: UIScene.ConnectionOptions) -> UISceneConfiguration {
// Called when a new scene session is being created.
// Use this method to select a configuration to create the new scene with.
return UISceneConfiguration(name: "Default Configuration", sessionRole: connectingSceneSession.role)
}
func application(_ application: UIApplication, didDiscardSceneSessions sceneSessions: Set<UISceneSession>) {
// Called when the user discards a scene session.
// If any sessions were discarded while the application was not running, this will be called shortly after application:didFinishLaunchingWithOptions.
// Use this method to release any resources that were specific to the discarded scenes, as they will not return.
}
// MARK: - Core Data stack
lazy var persistentContainer: NSPersistentContainer = {
/*
The persistent container for the application. This implementation
creates and returns a container, having loaded the store for the
application to it. This property is optional since there are legitimate
error conditions that could cause the creation of the store to fail.
*/
let container = NSPersistentContainer(name: "FacilityInspector")
container.loadPersistentStores(completionHandler: { (storeDescription, error) in
if let error = error as NSError? {
// Replace this implementation with code to handle the error appropriately.
// fatalError() causes the application to generate a crash log and terminate. You should not use this function in a shipping application, although it may be useful during development.
/*
Typical reasons for an error here include:
* The parent directory does not exist, cannot be created, or disallows writing.
* The persistent store is not accessible, due to permissions or data protection when the device is locked.
* The device is out of space.
* The store could not be migrated to the current model version.
Check the error message to determine what the actual problem was.

fatalError("Unresolved error \(error), \(error.userInfo)")
}
})
return container
}()
}
ContentView.swift
import SwiftUI
struct ContentView: View {
@Environment(\.scenePhase) private var scenePhase
var body: some View {
NavigationView{
SampleView()
}.onChange(of: scenePhase){ _, phase in
switch phase {
case .active:
print("scenePhase - active")
case .inactive:
print("scenePhase - inactive")
case .background:
print("scenePhase - background")
@unknown default:

}
}
}

Thank you in advance.
