im trying to auth through google and it seems like Auth.auth().signInAndRetrieveData is no more working.
func sign(_ signIn: GIDSignIn!, didSignInFor user: GIDGoogleUser!, withError error: Error!){
if let err = error {
print ("failed to log into Google", err)
return
}
print("successfully logged into 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, completion: { (user, error) in
if let err = error {
print ("failed to create with google account", err)
return
}
print("successfuly logged into Firebase with Google", user?.user.uid)
})
}
Auth.auth().signIn(with: credential) { (result, error) in
if error == nil{
//use result info and do what you want here
}else{
//or other wise print the error description and looking it
print("This is the Error: \(error?.localizedDescription)")
}
}

I have incorporated Google sign in into my app. It was working well this whole time and then suddenly stopped working, now giving me this error in the debugger:
Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: 'presentingViewController must be set.'
Here is my code for the login view controller (edited to show only necessary code):
class WelcomeViewController: UIViewController, GIDSignInDelegate {
#IBOutlet weak var signInGoogleButton: UIButton!
override func viewDidLoad() {
super.viewDidLoad()
setUpGoogleButton()
GIDSignIn.sharedInstance()?.presentingViewController = self
}
// MARK: - SIGN UP WITH GOOGLE
func sign(_ signIn: GIDSignIn!, didSignInFor user: GIDGoogleUser!, withError error: Error!) {
if let err = error {
print("Failed to log into Google: ", err)
return
}
print("Successfully logged into Google")
guard let authentication = user.authentication else { return }
let credential = GoogleAuthProvider.credential(withIDToken: authentication.idToken, accessToken: authentication.accessToken)
// sign user in with Firebase
Auth.auth().signIn(with: credential, completion: { (user, error) in
let firstName = user?.user.displayName
let email = user?.user.email
let lastName = ""
let uid = user?.user.uid
if let err = error {
print("Failed to create a Firebase User with Google account: ", err)
return
} else {
// Successfully logged in
print("Successfully logged into Firebase with Google email: ", email ?? "", "Now add user to Firestore if user is new.")
// check if user already exists
self.addUserToFirestore(firstName ?? "", lastName, email ?? "", uid ?? "", "Google")
}
})
}
fileprivate func setUpGoogleButton() {

#objc func handleCustomGoogleSignIn() {
GIDSignIn.sharedInstance().signIn()
}
// MARK: - Other functions
func addUserToFirestore(_ firstName:String, _ lastName:String, _ email:String, _ uid:String, _ signInMethod:String) {
let db = Firestore.firestore()
let docRef = db.collection("users").document(uid)
// check if user exists in firestore
docRef.getDocument { (document, error) in
if let document = document {
if document.exists {
let message = "Good news! You already have a Coal account that uses " + email + ".\nPlease sign in to your existing account. Then you will be able to link your " + signInMethod + " profile from your Account Settings page."

} // end
Here is the app delegate:
#UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate, GIDSignInDelegate {
func sign(_ signIn: GIDSignIn!, didSignInFor user: GIDGoogleUser!, withError error: Error!) {
if let err = error {
print("Failed to log into Google: ", err)
return
}
print("Successfully logged into Google")
guard let authentication = user.authentication else { return }
let credential = GoogleAuthProvider.credential(withIDToken: authentication.idToken, accessToken: authentication.accessToken)
Auth.auth().signIn(with: credential, completion: { (user, error) in
if let err = error {
print("Failed to create a Firebase User with Google account: ", err)
return
}
guard let uid = user?.user.uid else { return }
print("Successfully logged into Firebase with Google", uid)
})
}
func application(
_ application: UIApplication,
didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?
) -> Bool {
FirebaseApp.configure()
GIDSignIn.sharedInstance()?.clientID = FirebaseApp.app()?.options.clientID
GIDSignIn.sharedInstance()?.delegate = self
ApplicationDelegate.shared.application(
application,
didFinishLaunchingWithOptions: launchOptions
)
return true
}
#available(iOS 9.0, *)
func application(_ app: UIApplication, open url: URL, options: [UIApplication.OpenURLOptionsKey : Any] = [:]) -> Bool {
ApplicationDelegate.shared.application(
app,
open: url,
sourceApplication: options[UIApplication.OpenURLOptionsKey.sourceApplication] as? String,
annotation: options[UIApplication.OpenURLOptionsKey.annotation]
)
return GIDSignIn.sharedInstance().handle(url)
}
}
The error occurs every time I click the signInGoogleButton. Any help is appreciated, thank you!!
When I log in with Facebook in on a Real Device It will be stuck on the Facebook login page and don' return back to my app.
I have put facebook code in URL Schemes and put all code that need to put in info.plist.
This is all the code that i use to login Facebook by using firebase.
In Viewdidload
facebookButton.addTarget(self, action: #selector(handleCustomFBLogin), for: .touchUpInside)
Code that i use in Viewcontroller.
#objc func handleCustomFBLogin(sender:UIButton!){
LoginManager().logIn(permissions: ["email", "public_profile"], from: self) { (result, error) in
guard let result = result else {
print("No result found")
return
}
if result.isCancelled {
print("Facebook Login Cancelled")
} else if let error = error {
print("Process error \(error.localizedDescription)")
} else {
print("Logged in")
self.showEmailAddress()
self.actionfb()
}
}
}
func loginButton(_ loginButton: FBLoginButton, didCompleteWith result: LoginManagerLoginResult?, error: Error?){
if(error != nil){
print(error!)
return
}else{
print("Successfully Logged in using facebook")
showEmailAddress()
}
}
func actionfb(){
let accessToken = AccessToken.current
guard (accessToken?.tokenString) != nil else {return}
let credential = FacebookAuthProvider.credential(withAccessToken: accessToken!.tokenString)
// Perform login by calling Firebase APIs
Auth.auth().signInAndRetrieveData(with: credential) { (authResult, error) in
if let error = error {
self.showAlert(title: "error", message: "\(error.localizedDescription)")
return
}
self.performSegue(withIdentifier: "GoGo", sender: nil)
self.navigationController?.setNavigationBarHidden(true, animated: true)
}
}
func showEmailAddress(){
GraphRequest(graphPath: "/me", parameters: ["fields" : "id, name, first_name, last_name, email, birthday, picture"]).start { (connection, result, err) in
if(err != nil){
print("Failed to start GraphRequest", err ?? "")
return
}
print(result ?? "")
}
}
func loginButtonDidLogOut(_ loginButton: FBLoginButton){
print("Logged out of Facebook")
}
In Appdelegate
ApplicationDelegate.shared.application(application, didFinishLaunchingWithOptions: launchOptions)
This will happen only when i had test on real device!!, but in simulation this can work normally
I'm not exactly sure if this is the solution, but this fixed it for me.
I copied the OAuth redirect URI from my firebase, under Authentication -> Facebook
And then on my Facebook developer page, under Products -> Facebook Login -> Settings, I pasted it into Valid OAuth Redirect URIs
I then logged in by entering in my username and password into of clicking "Login with Facebook" and the error stopped happening.
I have no idea if the error will return, maybe this will be helpful to someone though.
I am using the Google authentication to authenticate users on Firebase. The code runs without errors, however, I am not seeing any of the authenticated users under the "authentication" tab of the Firebase console. There is user activity according to the analytics, but there is no record of any of the users that sign in using the Google sign-in.
func sign(_signIn: GIDSignIn!, didSignInfor user: GIDGoogleUser!, withError error: Error!){
if let err = error {
print ("failed to log into Google", err)
return
}
guard let authentication = user.authentication else { return }
let credential = GoogleAuthProvider.credential(withIDToken: authentication.idToken,
accessToken: authentication.accessToken)
Auth.auth().signInAndRetrieveData(with: credential, completion: { (authResult, error) in
if let error = error {
print ("failed to create with google account")
return
}
// User is signed in
guard let uid = user?.userID else {
return
}
I followed the documentation on Firebase and I have enabled "Google sign-in". Thanks in advance!
I have found the answer to the issue:
func sign(_ signIn: GIDSignIn!, didSignInFor user: GIDGoogleUser!, withError error: Error!){
if let err = error {
print ("failed to log into Google", err)
return
}
print("successfully logged into 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, completion: { (user, error) in
if let err = error {
print ("failed to create with google account", err)
return
}
print("successfuly logged into Firebase with Google", user?.user.uid)
})
}
The issue was with the first line of code, where "didSignInFor" was not properly capitalized. Likewise, there was a duplicate function that was calling the same sign-in function, which may have been another issue on why users were not showing up on the "authentication" tab of the Firebase console.
My project use Firebase and Facebook Authentication. It works fine, but when I choose to cancel the Facebook Authentication (the first time when i fetch the uid) the project crash.
Here is the method i use:
func loginButton(_ loginButton: FBSDKLoginButton!, didCompleteWith result: FBSDKLoginManagerLoginResult!, error: Error!) {
let credential = FacebookAuthProvider.credential(withAccessToken: FBSDKAccessToken.current().tokenString)
Auth.auth().signInAndRetrieveData(with: credential) { (user, error) in
// [START_EXCLUDE]
if let error = error {
print(error.localizedDescription)
return
}
self.uid = Auth.auth().currentUser?.uid
self.firstFetch()
// [END_EXCLUDE]
}
print("logged in")
}
Can Anyone help me, please?
Ok, the whole implementation of this function was wrong, because it was fetching the user no matter if it was authenticated or not. Here is the new method I wrote:
func loginButton(_ loginButton: FBSDKLoginButton!, didCompleteWith result:
FBSDKLoginManagerLoginResult!, error: Error!) {
if error != nil {
print("look a at your.. errm.. code, please", error.localizedDescription)
} else if result.isCancelled {
print("houston, we have a situation: the player cancelled the auth request")
} else {
let credential = FacebookAuthProvider.credential(withAccessToken: FBSDKAccessToken.current().tokenString)
Auth.auth().signInAndRetrieveData(with: credential) { (user, error) in
self.uid = Auth.auth().currentUser?.uid
print("you're in, remember: with great power comes great responsibility!")
self.firstFetch()
}
}
}
So I've been attempting to update my code to Swift 2.0 syntax, but I can't seem to get my Parse login to work. I looked over the documentation changes and added the result block for my login, but I'm getting the error "'(, ) throws -> Void' is not convertible to 'PFUserResultBlock?'"
Here is the line of code:
PFUser.logInWithUsernameInBackground(usernameTextField.text!, password: passwordTextField.text!, block: { (user,error) -> Void in
if user != nil {
This Code might solve your problem.
PFUser.logInWithUsername(inBackground: emailTextField.text!, password: passwordTextField.text!, block: { (user, error) in
self.activityIndicator.stopAnimating()
UIApplication.shared.endIgnoringInteractionEvents()
if error != nil {
var displayErrorMessage = "Please try again later"
let error = error as NSError?
if let errorMessage = error?.userInfo["error"] as? String {
displayErrorMessage = errorMessage
}
self.createAlert(title: "Login Error", message: displayErrorMessage)
} else {
print("logged inn")
self.performSegue(withIdentifier: "showUserTable", sender: self)
}
})
Try this version
PFUser.logInWithUsernameInBackground(usernameTextField.text!, password: passwordTextField.text!) { (user:PFUser?, error:NSError?) -> Void in
if user != nil {
print("Login Successful")
} else {
print("Login Failed")
}
}
