我很难搞清楚为什么firebase返回错误代码 17011 （根据Firebase文档是用户未找到错误），甚至在删除数据库中的所有用户和身份验证后创建具有电子邮件和密码的用户时firebase控制台的各个部分 . 虽然用户已成功创建并添加到firebase实时数据库，但错误代码仍会弹出 . 以下是在控制台上打印出来的完整错误：
可选（错误域= FIRAuthErrorDomain代码= 17011“没有与此标识符对应的用户记录 . 用户可能已被删除 . ”UserInfo = {NSLocalizedDescription =没有与此标识符对应的用户记录 . 用户可能已被删除 . ，error_name = ERROR_USER_NOT_FOUND}）！

import UIKit
import Firebase
class LoginViewController: UIViewController , UITextFieldDelegate {
@IBOutlet weak var emailField: RoundedCornerTextField!
@IBOutlet weak var passwordField: RoundedCornerTextField!
@IBOutlet weak var segmentedControl: UISegmentedControl!
override func viewDidLoad() {
super.viewDidLoad()
emailField.delegate = self
passwordField.delegate = self
}
@IBAction func signupLoginBtnTapped(_ sender: Any) {
if emailField.text != nil && passwordField.text != nil {
if let email = emailField.text, let password = passwordField.text {
Auth.auth().signIn(withEmail: email, password: password, completion: { (user, error) in //Sign in
if error == nil {
if let user = user {
if self.segmentedControl.selectedSegmentIndex == 0 {
let userData = ["provider": user.providerID] as [String: Any]
DataService.instance.createFirebaseDBUser(uid: user.uid, userData: userData)
} else {
let userData = ["provider": user.providerID] as [String: Any]
DataService.instance.createFirebaseDBUser(uid: user.uid, userData: userData)
}
}
print ("Firebase: Success authentication with Firebase.")
self.dismiss(animated: true, completion: nil)
} else {
if let errorCode = AuthErrorCode(rawValue: error!._code){
switch errorCode {
case.wrongPassword:
self.showAlert("You entered an invalid password please try again!")
default:
self.showAlert("Unexpected error \(errorCode.rawValue) please try again!")
print("Creating user error 1 \(error.debugDescription)!")
}
}
Auth.auth().createUser(withEmail: email, password: password, completion: { (user, error) in //creating a user
if error == nil {
if let user = user {
if self.segmentedControl.selectedSegmentIndex == 0 {
let userData = ["provider": user.providerID] as [String: Any]
DataService.instance.createFirebaseDBUser(uid: user.uid, userData: userData)
} else {
let userData = ["provider": user.providerID] as [String: Any]
DataService.instance.createFirebaseDBUser(uid: user.uid, userData: userData, isDriver: true)
}
} else {
if let errorCode = AuthErrorCode(rawValue: error!._code) {
switch errorCode {
case .invalidEmail:
self.showAlert("You entered an invalid email!")
case .userNotFound:
self.showAlert("User not found")
default:
print("Creating user error 2 \(error.debugDescription)!")
self.showAlert("Unexpected error \(errorCode.rawValue) please try again!")
}
}
}
print("Firebase: user created successfully")

发生错误的代码块：
Auth.auth().signIn(withEmail: email, password: password, completion: { (user, error) in
if error == nil {
if let user = user {
if self.segmentedControl.selectedSegmentIndex == 0 {
let userData = ["provider": user.providerID] as [String: Any]
DataService.instance.createFirebaseDBUser(uid: user.uid, userData: userData)
}
else {
let userData = ["provider": user.providerID]
DataService.instance.createFirebaseDBUser(uid: user.uid, userData: userData, isDriver: true)
}
}
print ("Firebase: Success authentication with Firebase.")
self.dismiss(animated: true, completion: nil)
}
else {
if let errorCode = AuthErrorCode(rawValue: error!._code){
switch errorCode {
case.wrongPassword:
self.showAlert("You entered an invalid password please try again!")
default:
self.showAlert("Unexpected error \(errorCode.rawValue) please try again!")
print("Creating user error \(error.debugDescription)!")
}
}
Auth.auth().createUser(withEmail: email, password: password, completion: { (user, error) in
if error == nil {
if let user = user {
if self.segmentedControl.selectedSegmentIndex == 0 {
let userData = ["provider": user.providerID] as [String: Any]
DataService.instance.createFirebaseDBUser(uid: user.uid, userData: userData)
}
else {
let userData = ["provider": user.providerID]
DataService.instance.createFirebaseDBUser(uid: user.uid, userData: userData, isDriver: true)
}
}
else {
if let errorCode = AuthErrorCode(rawValue: error!._code) {
switch errorCode {
case .invalidEmail:
self.showAlert("You entered an invalid email!")
case .userNotFound:
self.showAlert("User not found")
default:
print("Creating user error \(error.debugDescription)!")
self.showAlert("Unexpected error \(errorCode.rawValue) please try again!")
}
}
}
self.dismiss(animated: true, completion: nil)
}
该错误发生在下面的Auth.auth（） . signIn else块中：
Auth.auth().createUser(withEmail: email, password: password, completion: { (user, error) in
if error == nil {
if let user = user {
if self.segmentedControl.selectedSegmentIndex == 0 {
let userData = ["provider": user.providerID] as [String: Any]
DataService.instance.createFirebaseDBUser(uid: user.uid, userData: userData)
}
else {
let userData = ["provider": user.providerID]
DataService.instance.createFirebaseDBUser(uid: user.uid, userData: userData, isDriver: true)
}
}
else {
if let errorCode = AuthErrorCode(rawValue: error!._code) {
switch errorCode {
case .invalidEmail:
self.showAlert("You entered an invalid email!")
case .userNotFound:
self.showAlert("User not found")
default:
print("Creating user error \(error.debugDescription)!")
self.showAlert("Unexpected error \(errorCode.rawValue) please try again!")
}
}
}
self.dismiss(animated: true, completion: nil)
}
任何人都可以提供解决方案吗？
P.S是的我将firebase导入项目并且pod是最新的，并且启用了firebase控制台的身份验证部分中的电子邮件/密码登录方法 .

在查看代码一段时间之后，我发布了在进入createUser（）函数之前应该处理所有处理登录的错误 . 由于Firebase Auth中存在.userNotfound错误 . 在case.userNotFound中调用createUser（）解决了问题，如下所示：
