ios - 类型 'AuthDataResult' 的值没有成员 'providerID' Firebase 5.0

Question

我对最新版本的 FirebaseAuth 5.0 有疑问这是我的代码:

func registerUser (withEmail email: String, andPassword password: String, userCreationComplete: @escaping (_ status: Bool, _ error: Error?) -> ()){
    Auth.auth().createUser(withEmail: email, password: password) { (user, error) in
        guard let user = user else{
            userCreationComplete(false, error)
            return
        }
        let userData = ["provider": user.providerID, "email": user.email]
        DataService.instance.createDBUser(uid: user.uid, userData: userData)
        userCreationComplete(true, nil)
    }

}

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

根据reference docs ，createUser 函数通过 (FIRAuthDataResult?, Error?) 传递完成 block 。 FirAuthDataResult 与 User 不同，但它有一个 User 作为属性，可以像这样访问它:

func registerUser (withEmail email: String, andPassword password: String, userCreationComplete: @escaping (_ status: Bool, _ error: Error?) -> ()){
    Auth.auth().createUser(withEmail: email, password: password) { (authResult, error) in
        guard let user = authResult.user else {
            userCreationComplete(false, error)
            return
        }
        let userData = ["provider": user.providerID, "email": user.email]
        DataService.instance.createDBUser(uid: user.uid, userData: userData)
        userCreationComplete(true, nil)
    }
}
