With using firebase as well. My signup is working well and it registers users. But my login was working fine at start but now it allows anyone to go to the next view(login).
Here's my code:
SignInVC..
import UIKit
import Firebase
class SignInVC: UIViewController {
#IBOutlet weak var emailTF: UITextField!
#IBOutlet weak var passwordTF: UITextField!
#IBAction func onSignInTapped(_ sender: Any) {
guard let email = emailTF.text,
email != "",
let password = passwordTF.text,
password != ""
else {
AlertController.showAlert(self, title: "Missing Information", message: "Please fill in username and password")
return
}
Auth.auth().signIn(withEmail: email, password: password) { (user, error) in
guard error == nil
else {
AlertController.showAlert(self, title: "Oops!", message: error!.localizedDescription)
return
}
guard let user = user else {return}
print(user.email ?? "Missing email address")
print(user.displayName ?? "Missing name")
print(user.uid)
self.performSegue(withIdentifier: "signInSegue", sender: nil)
}
}
//remove keyboard
override func touchesBegan(_ touches: Set<UITouch>, with event: UIEvent?) {
self.view.endEditing(true)
}
}
AlerControllerVC
import UIKit
import Firebase
class AlertController {
static func showAlert(_ inViewController: UIViewController, title: String, message: String) {
let alert = UIAlertController(title: title, message: message, preferredStyle: .alert)
let action = UIAlertAction(title: "OK", style: .default, handler: nil)
alert.addAction(action)
inViewController.present(alert, animated: true, completion: nil)
}
}
I tried many was and rewrote it again but wont work correct again, when executed it says:
".SignInVC: 0x7fd99c208280> whose view is not in the window hierarchy!"
Please check if your segue is from button to ViewController or from ViewController to ViewController. if it is from button to VC then it does not depend upon the code you wrote

I have view controllers connected with my code that include a login page and a sign up page, I've started a firebase project and connected with my Xcode and it successfully connected to the firebase servers. The code below is for my sign up view controller and is supposed to act like a sign up form with email, password and password confirmation but for some reason the build succeeds with no errors but the user that registered does not show up on my firebase user database and the textfields don't act like the way they should (i.e throw an error if password and password confirmation don't match) .
import UIKit
import FirebaseAuth
import FirebaseCore
import Firebase
class SignUpViewController: UIViewController {
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view.
}
#IBAction func SignUpToHome(sender: AnyObject) {
performSegue(withIdentifier: "SignUpToHome", sender: sender)
}
#IBOutlet weak var email: UITextField!
#IBOutlet weak var password: UITextField!
#IBOutlet weak var passwordConfirm: UITextField!
#IBAction func signUpAction(_ sender: Any) {
//func signUpAction(_ sender: Any) {
//}
if password.text != passwordConfirm.text {
let alertController = UIAlertController(title: "Password Incorrect", message: "Please re-type password", preferredStyle: .alert)
let defaultAction = UIAlertAction(title: "OK", style: .cancel, handler: nil)
alertController.addAction(defaultAction)
self.present(alertController, animated: true, completion: nil)
}
else{
Auth.auth().createUser(withEmail: email.text!, password: password.text!){ (user, error) in
if error == nil {
self.performSegue(withIdentifier: "SignUpToHome", sender: self)
}
else{
let alertController = UIAlertController(title: "Error", message: error?.localizedDescription, preferredStyle: .alert)
let defaultAction = UIAlertAction(title: "OK", style: .cancel, handler: nil)
alertController.addAction(defaultAction)
self.present(alertController, animated: true, completion: nil)
}
}
}
}
}
I need to my button proceedToAppFeatures to run the code and display an alert of success or failure login(just a single user, for now)
I have tried self.showAlert and self.present
Code:
import UIKit
import FLAnimatedImage
import ImageIO
import UserNotifications//import this to use user notifications
import Firebase
class ViewController: UIViewController, UITextFieldDelegate{
#IBOutlet weak var background: FLAnimatedImageView!

#IBOutlet weak var lblValidationMessage: UILabel!
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view.
background.loadGif(name: "neon lights")
passwordTextField.isSecureTextEntry = true// the password will no be visible
emailTextField.delegate = self
passwordTextField.delegate = self
let Tap:UITapGestureRecognizer = UITapGestureRecognizer(target: self, action: #selector(DismissKeyboard))//here i have used the function to didmiss the keyboard
view.addGestureRecognizer(Tap)
let center = UNUserNotificationCenter.current()
//this initialize the permission that will appear on user screen
center.requestAuthorization(options: [.alert, .sound, .badge]) {
(granted,error) in
//enable or disable features based on the authorization
}
// emailTextField.text = ""
// passwordTextField.text = ""//on view did load to store text field property
}
#objc func DismissKeyboard() {//function that implements the type outside the screen
view.endEditing(true)
}
#IBAction func sigInButton(_ sender: UIButton) {
performSegue(withIdentifier: "userData", sender: true)
}
func textFieldShouldReturn(_ textField: UITextField) -> Bool {
if textField == emailTextField {
textField.resignFirstResponder()
}else{
passwordTextField.becomeFirstResponder()//just to decide which of the buttons will respond after a tab is pressed
passwordTextField.resignFirstResponder()
}
return true
}
func showAlert(title: String, message: String){
let alert = UIAlertController(title: title, message: message, preferredStyle: UIAlertController.Style.alert)
alert.addAction(UIAlertAction(title: "OK", style: UIAlertAction.Style.default, handler: {(action) in alert.dismiss(animated: true, completion: nil)}))
self.present(alert, animated: true, completion: nil)
}
func isValidEmail(testStr:String) -> Bool {
let emailRegEx = "[A-Z0-9a-z._%+-]+#[A-Za-z0-9.-]+\\.[A-Za-z]{2,64}"
let emailTest = NSPredicate(format:"SELF MATCHES %#", emailRegEx)
return emailTest.evaluate(with: testStr)
}
#IBAction func proceedToAppFeatures(_ sender: Any) {
let email = isValidEmail(testStr: emailTextField.text!)
if email == false{
self.showAlert(title: "ERROR", message: "This is not a valid e-mail. Please try again")
emailTextField.text = ""
}else{
self.showAlert(title: "Success", message: "Yousucessifully loged in")
//performSegue(withIdentifier: "formPage", sender: true)
}
let myEmail: String!
myEmail = emailTextField.text!
let myPassword: String!
myPassword = passwordTextField.text!
if(myEmail == "leandroaaramos" && myPassword == "123456"){
//performSegue(withIdentifier: "homeSegue", sender: nil)
//code for the truth
print("You are success")
}else if (myEmail.isEmpty && myPassword.isEmpty){
//here i put the alert message
let alert = UIAlertController(title: "Wow", message: "Hold on fill the gaps", preferredStyle: UIAlertController.Style.alert)
//add an action to the alert
alert.addAction(UIAlertAction(title: "Close", style: UIAlertAction.Style.default, handler: nil))
self.present(alert, animated: true, completion: nil)
self.showAlert(title: "Empty field", message: "Try again")
}else {
//here i put the alert message
let alert = UIAlertController(title: "Ops", message: "Your account is not here", preferredStyle: UIAlertController.Style.alert)
//add an action to the alert
alert.addAction(UIAlertAction(title: "Try Again", style: UIAlertAction.Style.default, handler: nil))
self.present(alert, animated: true, completion: nil)
self.showAlert(title: "Sorry", message: "Can't find you.")
}
}
}
I want go to my loginViewController, if the user leandroaaramos and password 123456 was typed.
After writing the log in with mail, i'm integrating social logins to my app and starting with Google signin. It now logs in automatically at app start, not if I press the Google login button. If I cancel it at pop up window it throws an Thread 1: Fatal error: Unexpectedly found nil while unwrapping an Optional valueon the token line in AppDelegate`. Also logging out doesn't prevent to log in automatically again.
It was quite confusing following instruction from Firebase manual for Google login so I sure made some obvious mistake.
Here's the code so far:
AppDelegate:
// start google sign in methods
#available(iOS 9.0, *)
func application(_ application: UIApplication, open url: URL, options: [UIApplicationOpenURLOptionsKey : Any])
-> Bool {
return GIDSignIn.sharedInstance().handle(url,
sourceApplication:options[UIApplicationOpenURLOptionsKey.sourceApplication] as? String,
annotation: options[UIApplicationOpenURLOptionsKey.annotation])
}
func sign(_ signIn: GIDSignIn!, didSignInFor user: GIDGoogleUser!, withError error: Error?) {
// ...
print("User successfully signed in with Google",user)
guard let idToken = user.authentication.idToken else {
return
}
guard let accessToken = user.authentication.accessToken else {return}
let credentials = GoogleAuthProvider.credential(withIDToken: idToken, accessToken: accessToken)
Auth.auth().signInAndRetrieveData(with: credentials) { (user, error) in
if let error = error {
print("Failed to create user with Google account", error)
return
}
print("Succesfully created new user in Firebase with Google account")
}
if let error = error {
// ...
print("User failed to sign in with Google", error)
return
}
guard let authentication = user.authentication else { return }
let credential = GoogleAuthProvider.credential(withIDToken: authentication.idToken,
accessToken: authentication.accessToken)
// let storyboard = UIStoryboard(name: "Main", bundle: nil)
// var mainVC = self.window?.visibleViewController as? MainNavigationController
// mainVC = storyboard.instantiateViewController(withIdentifier: "MainNavigationController") as? MainNavigationController
}
func sign(_ signIn: GIDSignIn!, didDisconnectWith user: GIDGoogleUser!, withError error: Error!) {
// Perform any operations when the user disconnects from app here.
// ...
}
// end of google sign in
The Google signin should perform a segue to main menu but it doesn't.
Only at first sign in it gets to the desired vc.
Here's the Login class:
import UIKit
import Firebase
import GoogleSignIn
class LoginViewController: UIViewController, GIDSignInUIDelegate {
// outlets
#IBOutlet weak var backGroundImage: UIImageView!
#IBOutlet weak var userNameTextField: UITextField!
#IBOutlet weak var emailTextField: UITextField!

setFacebookButton()
}
// dismiss keyboard on touch outside textfields
override func touchesBegan(_ touches: Set<UITouch>, with event: UIEvent?) {

if txt.isKind(of: UITextField.self) && txt.isFirstResponder {
txt.resignFirstResponder()
}
}
}
private func setGoogleButton() {
GIDSignIn.sharedInstance().uiDelegate = self
GIDSignIn.sharedInstance().signIn()
}
private func setFacebookButton() {
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}

#IBAction func newUserRegisterButton(_ sender: Any) {
if passwordTextField.text != confirmPasswordTextField.text{
let alertController = UIAlertController(title: "Password Incorrect", message: "Please re-type password", preferredStyle: .alert)
let defaultAction = UIAlertAction(title: "OK", style: .cancel, handler: nil)
alertController.addAction(defaultAction)
self.present(alertController, animated: true, completion: nil)
}
else{

}
else{

let defaultAction = UIAlertAction(title: "OK", style: .cancel, handler: nil)
alertController.addAction(defaultAction)
self.present(alertController, animated: true, completion: nil)
}
}
}
}
#IBAction func mailLogin(_ sender: UIButton) {

self.performSegue(withIdentifier: "skipSegue", sender: self)
}
else{
let alertController = UIAlertController(title: "Error", message: error?.localizedDescription, preferredStyle: .alert)
let defaultAction = UIAlertAction(title: "OK", style: .cancel, handler: nil)
alertController.addAction(defaultAction)

}
}
}
#IBAction func facebookLogin(_ sender: UIButton) {
}
#IBOutlet weak var signInButton: GIDSignInButton!
#IBAction func googleSignInButton(_ sender: GIDSignInButton) {
performSegue(withIdentifier: "skipSegue", sender: self)
}
#IBAction func logoutButton(_ sender: UIButton) {
}
#IBAction func skipButton(_ sender: UIButton) {
performSegue(withIdentifier: "skipSegue", sender: self)
}
}
The sign out:
#IBAction func logOutButton(_ sender: UIButton) {
// firebase auth sign out
let firebaseAuth = Auth.auth()
do {
try firebaseAuth.signOut()
} catch let signOutError as NSError {
print ("Error signing out: %#", signOutError)
}
// GSI log out
GIDSignIn.sharedInstance().signOut()
print("User successfully logged out Firebase with Google account")
let storyboard = UIStoryboard(name: "Main", bundle: nil)
let initial = storyboard.instantiateInitialViewController()
UIApplication.shared.keyWindow?.rootViewController = initial
}
func signOutOverride() {
do {
GIDSignIn.sharedInstance().signOut()
try GIDSignIn.sharedInstance()?.disconnect()
// Set the view to the login screen after signing out
let storyboard = UIStoryboard(name: "Main", bundle: nil)
let initial = storyboard.instantiateInitialViewController()
UIApplication.shared.keyWindow?.rootViewController = initial
// let storyboard = UIStoryboard(name: "SignIn", bundle: nil)
// let loginVC = storyboard.instantiateViewControllerWithIdentifier("SignInVC") as! SignInViewController
// let appDelegate = UIApplication.sharedApplication().delegate as! AppDelegate
// appDelegate.window?.rootViewController = loginVC
} catch let signOutError as NSError {
print ("Error signing out: \(signOutError)")
}
}
I read many posts about revoking the tokens and disconnect the user from the app, but couldn't implement those solutions as some are in obj-c and others in older swift syntax.
Anyone having same problem as me?
Thank as usual.
After many tries and error,thanks to Google's sarcastically useful documentation, I found out what the problem was. They suggest to put the sign in inside viewDidLoad()' and that obviously get's called every time the VC gets instantiated. I so Moved into the Google sign in button and left the delegate only inviewDidLoad()
It all now works as expected.
override func viewDidLoad() {
super.viewDidLoad()
GIDSignIn.sharedInstance().uiDelegate = self
setFacebookButton()
}
#IBOutlet weak var signInButton: GIDSignInButton!
#IBAction func googleSignInButton(_ sender: GIDSignInButton) {
GIDSignIn.sharedInstance()?.signIn()
performSegue(withIdentifier: "skipSegue", sender: self)
}
I have followed the sample here
https://github.com/awslabs/aws-sdk-ios-samples/tree/master/CognitoYourUserPools-Sample
To integrate interactive cognito login to my iOS app. This is all working well, but when a new user is created in the pool, they initially have a FORCE_CHANGE_PASSWORD status.
For android you can follow the procedure below
http://docs.aws.amazon.com/cognito/latest/developerguide/using-amazon-cognito-user-identity-pools-android-sdk-authenticate-admin-created-user.html
But for iOS I can't find out how to do this. Using the sample, if I attempt to login with a user in FORCE_CHANGE_PASSWORD status, I see the following output in the console logs (with some values removed for brevity):
{"ChallengeName":"NEW_PASSWORD_REQUIRED","ChallengeParameters":{"requiredAttributes":"[]","userAttributes":"{\"email_verified\":\"true\",\"custom:autoconfirm\":\"Y\","Session":"xyz"}
The following is the code from the SignInViewController from the sample detailed above.
import Foundation
import AWSCognitoIdentityProvider
class SignInViewController: UIViewController {
#IBOutlet weak var username: UITextField!
#IBOutlet weak var password: UITextField!
var passwordAuthenticationCompletion: AWSTaskCompletionSource<AWSCognitoIdentityPasswordAuthenticationDetails>?
var usernameText: String?
override func viewWillAppear(_ animated: Bool) {
super.viewWillAppear(animated)
self.password.text = nil
self.username.text = usernameText
self.navigationController?.setNavigationBarHidden(true, animated: false)
}
#IBAction func signInPressed(_ sender: AnyObject) {
if (self.username.text != nil && self.password.text != nil) {
let authDetails = AWSCognitoIdentityPasswordAuthenticationDetails(username: self.username.text!, password: self.password.text! )
self.passwordAuthenticationCompletion?.set(result: authDetails)
} else {
let alertController = UIAlertController(title: "Missing information",
message: "Please enter a valid user name and password",
preferredStyle: .alert)
let retryAction = UIAlertAction(title: "Retry", style: .default, handler: nil)
alertController.addAction(retryAction)
}
}
}
extension SignInViewController: AWSCognitoIdentityPasswordAuthentication {
public func getDetails(_ authenticationInput: AWSCognitoIdentityPasswordAuthenticationInput, passwordAuthenticationCompletionSource: AWSTaskCompletionSource<AWSCognitoIdentityPasswordAuthenticationDetails>) {
self.passwordAuthenticationCompletion = passwordAuthenticationCompletionSource
DispatchQueue.main.async {
if (self.usernameText == nil) {
self.usernameText = authenticationInput.lastKnownUsername
}
}
}
public func didCompleteStepWithError(_ error: Error?) {
DispatchQueue.main.async {
if let error = error as? NSError {
let alertController = UIAlertController(title: error.userInfo["__type"] as? String,
message: error.userInfo["message"] as? String,
preferredStyle: .alert)
let retryAction = UIAlertAction(title: "Retry", style: .default, handler: nil)
alertController.addAction(retryAction)
self.present(alertController, animated: true, completion: nil)
} else {
self.username.text = nil
self.dismiss(animated: true, completion: nil)
}
}
}
}
When didCompleteStepWithError executes, error is null where I would expect it to indicate something to tell us that the user is required to change password.
My question is really how to catch the "ChallengeName":"NEW_PASSWORD_REQUIRED" json that is output to the console?
Sorted this now. Posting it here in case it helps anyone else.
First, you need to create a view controller that will allow the user to specify the new password. The ViewController should have a AWSTaskCompletionSource<AWSCognitoIdentityNewPasswordRequiredDetails> as a property:
var newPasswordCompletion: AWSTaskCompletionSource<AWSCognitoIdentityNewPasswordRequiredDetails>?
Following the pattern in the sample referred to in the question, I then implemented AWSCognitoIdentityNewPasswordRequired as an extension to the view controller as follows:
extension NewPasswordRequiredViewController: AWSCognitoIdentityNewPasswordRequired {
func getNewPasswordDetails(_ newPasswordRequiredInput: AWSCognitoIdentityNewPasswordRequiredInput, newPasswordRequiredCompletionSource:
AWSTaskCompletionSource<AWSCognitoIdentityNewPasswordRequiredDetails>) {
self.newPasswordCompletion = newPasswordRequiredCompletionSource
}
func didCompleteNewPasswordStepWithError(_ error: Error?) {
if let error = error as? NSError {
// Handle error
} else {
// Handle success, in my case simply dismiss the view controller
self.dismiss(animated: true, completion: nil)
}
}
}
Again following the design of the sample detailed in the question, add a function to the AWSCognitoIdentityInteractiveAuthenticationDelegate extension to AppDelegate:
extension AppDelegate: AWSCognitoIdentityInteractiveAuthenticationDelegate {
func startPasswordAuthentication() -> AWSCognitoIdentityPasswordAuthentication {
//Existing implementation
}
func startNewPasswordRequired() -> AWSCognitoIdentityNewPasswordRequired {
// Your code to handle how the NewPasswordRequiredViewController is created / presented, the view controller should be returned
return self.newPasswordRequiredViewController!
}
}
The perfect example to implement the ResetPassword when u create the user in Cognito Console.
But, Integrating this ResetPassword mechanism to your existing app is your responsibility.

The error message screenshot:
When I click the "click here" button in the paragraph that says "If you forgot your username/password, click here to send a verification message that contains your username/password to your email address", the dialogue box pops up and says "MailCompositionService quit unexpectedly", and that message is the error I want to solve.
This class below this sentence is the Swift code for the page that has the "click here" button which generates the error I want to solve. It is the ViewController class.

EDIT #2: I would post more screenshots of the storyboard links but I can only post two, so let me know and I'll email them.
The MailCompositionService quit unexpectedly error is a simulator bug. Run your mail sending code on a real device to test it.
This is simulator problem not your problem , Try to connect your iPhone using usb and select it from Xcode then run the application , it should work without error , if there is an errors let us know
