Sign Out of Firebase in Swift 4

Question

I want to do sign out from my application after i signing in with firebase, and i tried this code in my application but it not working.

print("clickSignOut")
        do {
            try Auth.auth().signOut()
       } catch {
         print("can't signOut")strong text
       }
      print(Auth.auth().currentUser ?? "no user")

The Firebase auth session is stored in the users keychain which is why it looks like they are still authenticated with the print statement. You need to manually remove that keychain data using the technique in the linked question. See [this answer](https://stackoverflow.com/questions/39301815/firebase-ios-swift-firauth-auth-signout-not-signing-out-current-user#answer-40412452) for some code suggestions as well. — Jay, Nov 11 '19 at 20:40

This always works for me:

do {
    try Auth.auth().signOut()
} catch let error {
    print("Error: ", error.localizedDescription)
}

If this isn't working for you, provide us with some more context. What do you mean by "it's not working"? If you use this code provided, it will tell what error you're encountering.

i tried it, its not working as well – Ahmad Binmana Nov 11 '19 at 21:17
How is it not working though? Is the error getting called or is this `try` line not even being attempted? Can you set some breakpoints to understand the flow better? – David Chopin Nov 11 '19 at 21:20
no its not getting an error but its not signOut when i clicked on the item bar button – Ahmad Binmana Nov 11 '19 at 21:43
Can you set a breakpoint within your button's `@IBAction` function to ensure that the code is even being called? – David Chopin Nov 11 '19 at 21:51
Okay i will, i will do it – Ahmad Binmana Nov 12 '19 at 22:19

Thank you so much its working now – Ahmad Binmana Nov 13 '19 at 22:08
Isn’t this a duplicate of the code in the question? – Jay Nov 14 '19 at 00:24
Basically yeah, but I added error handling for the try statement. It seems, however, that his code wasn't even being run – David Chopin Nov 14 '19 at 00:33

Can you share your code? – Parth Nov 11 '19 at 21:29
okay of course. – Ahmad Binmana Nov 11 '19 at 21:43
@IBAction func signOutButtonTapped(_ sender: Any) { do { try Auth.auth().signOut() } catch let error { print("Error: ", error.localizedDescription) } – Ahmad Binmana Nov 11 '19 at 21:48
Not this. Is the whole code on GitHub? – Parth Nov 11 '19 at 22:23
No, i will upload it on the GitHub. – Ahmad Binmana Nov 12 '19 at 22:17
Did you upload it? – Parth Nov 14 '19 at 14:51
No i didn't because it's working now, and much appreciated you helped me to figure out a solution. – Ahmad Binmana Nov 15 '19 at 10:30
You are welcome! An upvote would help. :D – Parth Nov 15 '19 at 16:09
