iOS "Lost connection to device" Error

[ufukhawk]

Hello,

Although I have made all the settings "await FlutterDownloader.initialize (debug: true);" As soon as this code runs, I get a "Lost connection to device" error on the simulator device and there is no other information other than this message.

my AppDelegate.swift

 `import UIKit
  import Flutter
  import Firebase
  import flutter_downloader

      @UIApplicationMain
      @objc class AppDelegate: FlutterAppDelegate {
        override func application(
          _ application: UIApplication,
          didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?
        ) -> Bool {
          GeneratedPluginRegistrant.register(with: self)
          return super.application(application, didFinishLaunchingWithOptions: launchOptions)
           FirebaseApp.configure()
              if #available(iOS 10.0, *) {
                UNUserNotificationCenter.current().delegate = self as? UNUserNotificationCenterDelegate
              }
              FlutterDownloaderPlugin.setPluginRegistrantCallback(registerPlugins)
              return super.application(application, didFinishLaunchingWithOptions: launchOptions)
        }
          let MY_BACKGROUND_SCREEN_TAG = 1001
          override func  applicationDidEnterBackground(_ application: UIApplication) {
              // Visual effect view for blur
              let blurEffect = UIBlurEffect(style: .dark)
              let blurView = UIVisualEffectView(effect: blurEffect)
              blurView.autoresizingMask = [.flexibleWidth, .flexibleHeight]
              blurView.frame = window.frame
              blurView.tag = MY_BACKGROUND_SCREEN_TAG

              window.addSubview(blurView)
          }

          override func applicationWillEnterForeground(_ application: UIApplication) {
              // remove blur view if present
              let view = window.viewWithTag(MY_BACKGROUND_SCREEN_TAG)
              if let view = view {    
                  UIView.animate(withDuration: 0.2, animations: {
                      view.alpha = 0

                  }) { finished in
                      view.removeFromSuperview()
                  }
              }
          }
      }

      private func registerPlugins(registry: FlutterPluginRegistry) {
          if (!registry.hasPlugin("FlutterDownloaderPlugin")) {
             FlutterDownloaderPlugin.register(with: registry.registrar(forPlugin: "FlutterDownloaderPlugin")!)
          }
      }

If I use an AppDelegate like in the document, it works. but i need to use Firebase?

      import UIKit
      import Flutter
      import flutter_downloader

      @UIApplicationMain
      @objc class AppDelegate: FlutterAppDelegate {
        override func application(
          _ application: UIApplication,
          didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?
        ) -> Bool {
          GeneratedPluginRegistrant.register(with: self)
          FlutterDownloaderPlugin.setPluginRegistrantCallback(registerPlugins)
          return super.application(application, didFinishLaunchingWithOptions: launchOptions)
        }
      }

      private func registerPlugins(registry: FlutterPluginRegistry) { 
          if (!registry.hasPlugin("FlutterDownloaderPlugin")) {
             FlutterDownloaderPlugin.register(with: registry.registrar(forPlugin: "FlutterDownloaderPlugin")!)
          }
      }
