ios - Sign-in With Apple Didn t get privaterelay appleid com when hide email in Simulator

Question

I'm working on Apple Sign In in Simulator iOS 13.4.1 and XCode Version 11.4.1.

I used to get privaterelay.appleid.com when Hide Email before but after changing my Laptop and try to test Apple Sign In in Simulator again, I got nil result. For other email when I didn't activate Hide Email it's still working and not give me any nil result.

Here my code:

// Create class for object first
class AppleUser{
    var id: String?
    var firstName: String?
    var lastName: String?
    var email: String?

    @available(iOS 13.0, *)
    init(credentials: ASAuthorizationAppleIDCredential) {
        id = credentials.user
        firstName = credentials.fullName?.givenName ?? ""
        lastName = credentials.fullName?.familyName ?? ""
        email = credentials.email ?? ""
    }
}

extension AppleUser: CustomDebugStringConvertible{
    var debugDescription: String{
        return """
        ID: \(id ?? "")
        First Name: \(firstName ?? "")
        Last Name: \(lastName ?? "")
        Email: \(email ?? "")
        """
    }
}

    // on ViewController
    @objc
    func didTapAppleButton(){
        if #available(iOS 13.0, *) {
            let provider = ASAuthorizationAppleIDProvider()
            let request = provider.createRequest()
            request.requestedScopes = [.fullName, .email]

            let controller = ASAuthorizationController(authorizationRequests: [request])

            controller.delegate = self
            controller.presentationContextProvider = self

            controller.performRequests()

        } else {
            // failed
        }
    }

extension ViewController: ASAuthorizationControllerDelegate, ASAuthorizationControllerPresentationContextProviding{

    @available(iOS 13.0, *)
    func presentationAnchor(for controller: ASAuthorizationController) -> ASPresentationAnchor {
        return view.window!
    }


    func authorizationController(controller: ASAuthorizationController, didCompleteWithAuthorization authorization: ASAuthorization) {
        switch authorization.credential {
        case let credentials as ASAuthorizationAppleIDCredential:
            let user = AppleUser(credentials: credentials)
            print(user)
            /*

        default:
