Issue #746

From iOS 13, the default is to support multiple scene, so the the old UIApplicationDelegate lifecycle does not work. Double check your Info.plist for UIApplicationSceneManifest key


One way to be notified about application life cycle is to use UIApplicationDelegateAdaptor and via NotificationCenter

import SwiftUI
import UIKit
import FontAwesomeSwiftUI

final class AppDelegate: NSObject, UIApplicationDelegate {
    func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey : Any]? = nil) -> Bool {
        return true

struct MyAwesomeApp: App {
    var appDelegate

    var body: some Scene {
        WindowGroup {
            MainView(store: Store.shared)
                        for: UIApplication.didEnterBackgroundNotification)) { _ in
