Swift NotificationCenter not receiving post

Question

I am trying to send a notification when a user re-signs in with Apple.

I have three parts:

1. Extension:

extension Notification.Name {
    static let userSignedIn = NSNotification.Name(rawValue: "userSignedIn")
}

2. Post Notification:

       if let userIdentifier = UserDefaults.standard.object(forKey: "appleSignIn") as? (String) {
   
                      let authorizationProvider = ASAuthorizationAppleIDProvider()
                      authorizationProvider.getCredentialState(forUserID: userIdentifier) { (state, error) in
                          switch (state) {
                          case .authorized:
                            print("Account Found - Signed In")
                            DispatchQueue.main.async {
   
                               NotificationCenter.default.post(name: .userSignedIn, object: nil)
   
                            }
                            break
                          case .revoked:
                              print("No Account Found")
                              fallthrough
                          case .notFound:
                               print("No Account Found")
                               DispatchQueue.main.async {
                               }
   
   
                          default:
                            break
                          }
   
                      }
               }
   

3. Receive notification:

   NotificationCenter.default.addObserver(self, selector: #selector(profileLaunch(_:)), name: .userSignedIn, object: nil)

I can't tell whether the notification is not getting posted or the observer is not getting called. Thanks!
