Xcode Swift : appDelgate.window! is nil : Fatal error: Unexpectedly found nil while unwrapping an Optional value

Question

I'm using MBProgressHUD to show a loader, and when acessing the app window the value in nil and the app crashes. I already imported the MBProgressHUD and created a variable appDelgate equals to UIApplication.shared.delegate as! AppDelegate, and when accessing that variable window! I get the follwing error: Fatal error: Unexpectedly found nil while unwrapping an Optional value

Code:

import MBProgressHUD
let appDelgate = UIApplication.shared.delegate as! AppDelegate
MBProgressHUD.showAdded(to: appDelgate.window!, animated: true)

I cant seem to find what I missing here

Are you using main interface or created a window yourself e.g self.window = UIWindow(frame: UIScreen.main.bounds) in App delegate? — RTXGamer, Jul 08 '21 at 20:02
@RTXGamer i'm using in AppDelegate.swift in the main window, basically on the app startup i'm sending a request to an api ro register a token. — rocket_moon, Jul 08 '21 at 21:41
@bmpf_pt, they've moved `window` to the `scene delegate` in iOS 13. — user28434'mstep, Jul 09 '21 at 06:22

You have to add var window: UIWindow? property in AppDelegate.swift. You can refer to this link

The app delegate must implement the window property if it wants to use a main storyboard file swift
