applicationDidFinishLaunching does not get triggered

Trying to understand what mistake I am doing with the following code. This is to be a Mac application, Xcode version 12.4. My problem is that applicationDidFinishLaunching never gets triggered.

import SwiftUI

@main
struct TestApp: App {
    @NSApplicationDelegateAdaptor(AppDelegate.self) var Delegate
    var body: some Scene {
        WindowGroup {
            ContentView()
        }
    }
}


class AppDelegate: NSObject, NSApplicationDelegate {
    func applicationDidFinishLaunching(aNotification: NSNotification) {
        let alert = NSAlert.init()
        alert.messageText = "Hello world"
        alert.informativeText = "Information text"
        alert.addButton(withTitle: "OK")
        alert.addButton(withTitle: "Cancel")
        alert.runModal()
    }
}

You have typing mistake. It's not an "a" it's a "_"

class AppDelegate: NSObject, NSApplicationDelegate {
    func applicationDidFinishLaunching(_ notification: Notification) { //<here
        let alert = NSAlert.init()
        alert.messageText = "Hello world"
        alert.informativeText = "Information text"
        alert.addButton(withTitle: "OK")
        alert.addButton(withTitle: "Cancel")
        alert.runModal()
    }
}
