Firebase "sign in method is disabled" despite having enabled it

Question

I am configuring my login page for my app, and trying to add a section where users can connect to firebase... Im trying to use firebase auth to sign up new users, but I get this error when running this code

 if (newRegistrationEmail.text != "" && newRegistrationUsername.text != "" && newRegistrationPassword.text != "" && newRegistrationRepeatedPassword.text != "")
 {
    FIRAuth.auth()?.createUser(withEmail: newRegistrationEmail.text!, password: newRegistrationPassword.text!, completion: 
    {
       user, error in

       if error != nil {
            print(error)
       }

The error:

Optional(Error Domain=FIRAuthErrorDomain Code=17006 "The given sign-in provider is disabled for this Firebase project. Enable it in the Firebase console, under the sign-in method tab of the Auth section." UserInfo={NSLocalizedDescription=The given sign-in provider is disabled for this Firebase project. Enable it in the Firebase console, under the sign-in method tab of the Auth section., error_name=ERROR_OPERATION_NOT_ALLOWED})

I've checked my Firebase console, and I have the email option enabled, so Im not sure why it won't let me use email in my code. Any ideas on how to fix it?? Thanks so much!!

Just had the same issue. I was trying to add to an existing Firebase project, so I skipped all of the setup steps under the assumption that my project would just work because it was already enabled. Here's what worked for me:

1. Delete the GoogleService-Info.plist file in your project folder.
2. On Firebase, navigate to your project's Settings page.
3. Re-download GoogleService-Info.plist
4. Drag it into your project folder.

Hope this helps! This was a super frustrating error!
