title: Creating new user with firebase in Swift
body: <p>I am new to Firebase and have been trying to implement a "Sign Up" page for my app. Currently, I am only using the email feature, just to test things out. I am able to create the new user and store it in the "Login &amp; Auth" tab in the dashboard, but for what ever reason I cannot retrieve the UID. The only way is if I close out of my app and reload it, then it can access the UID. Any suggestions on why this is?</p>
