swift - 类型 'AuthDataResult' 的值没有成员 'providerID'

Question

我在使用最新版本的 FirebaseAuth 5.0 时遇到问题，这是我的代码:

if let email = emailField.text, let password = passwordField.text {          
    Auth.auth().signIn(withEmail: email, password: password) { (user, error) in
        if error == nil {
           if let user = user {
               if self.segmentedControl.selectedSegmentIndex == 0 {
                  let userData = ["provider": user.providerID] as [String: Any]

问题是“‘AuthDataResult’类型的值没有值‘ProviderID’”，但在 firebase 4 中此方法有效。谢谢!

AuthDataResult有一个属性 user 具有 providerID。您不应将 AuthDataResult 视为 completion 中的 user。您可以按如下方式访问 providerId，

if let email = emailField.text, let password = passwordField.text {          
    Auth.auth().signIn(withEmail: email, password: password) { (authData, error) in
        if error == nil {
           if let user = authData?.user {
               if self.segmentedControl.selectedSegmentIndex == 0 {
                  let userData = ["provider": user.providerID] as [String: Any]
