title: Firebase Authentication does not insert new values
body: <p>I recently updated to the newest version of Xcode and I've got a lot of problems since then. I've a "Sign up" form where user can create a new account on the app but somehow it does not insert new values into the Authentication.</p>
  
  <p>I commented out my code and just tried to run the normal create user function so my code looks like this right now:</p>
  
  <pre><code>        Auth.auth().createUser(withEmail: txtfield_email.text!, password: txtfield_password.text!) { (adr, err) in
          if let err = err{
              print(err.localizedDescription)
          }else{
              print("Succeded creating a new user!")
          }
      }
  </code></pre>
  
  <p>So when I run the app it will go into the else and print out: "Succeded creating a new user!" but when I login to my Firebase account and check if any new values is added to the authentication the answer is no. Nothing is there. </p>
  
  <p>I've updated all my pods including the Firebase and still does not work. </p>
  
  <p>What could of happen? Why doesn't it run like normal? </p>
  
  <p>Just to mention: I'm currently running it on the simulator (Not my own device). But like I said, nothing new is getting implemented in Authentication. (Everything worked perfectly fine before, but not after I updated...?)</p>
