我正在使用Apple实施Sign in，并注意到返回的email和fullName属性ASAuthorizationAppleIDCredential仅在此Apple ID的第一个Sign-In上填写。在所有后续登录中，这些属性均为零。

这是iOS 13上的错误还是预期的行为？

这是我用来启动请求的代码：

@available(iOS 13.0, *)
dynamic private func signInWithAppleClicked() {
    let request = ASAuthorizationAppleIDProvider().createRequest()
    request.requestedScopes = [.fullName, .email]

    let controller = ASAuthorizationController(authorizationRequests: [request])
    controller.delegate = self
    controller.presentationContextProvider = self
    controller.performRequests()
}

我正在此委托方法中收到证书：

public func authorizationController(controller: ASAuthorizationController, didCompleteWithAuthorization authorization: ASAuthorization) {
    guard let credential = authorization.credential as? ASAuthorizationAppleIDCredential else { return }

    let userIdentifier = credential.user
    let token = credential.identityToken
    let authCode = credential.authorizationCode
    let realUserStatus = credential.realUserStatus
    let mail = …
