Tutorial says select Realtime Database and then select Rules, but no database exists

I think the tutorial is probably missing an instruction to create a database?
On this page: https://firebase.google.com/codelabs/firebase-ios-swift#4
It says "From within the Database section of Firebase console select Realtime Database, then click on the Rules tab" but I didn't have a Rules tab, just a big Create database button. I had to create database before I could access rules.

I suspect the UI has changed here too. In the instructions it says "Navigate to the Firebase console => Select Authentication", and same for database, but in both cases I had to click "All products" at the bottom before I could see database or authentication. In the case of authentication, I then had to click something like "Get started" before I saw the signin method tab. Here: https://firebase.google.com/codelabs/firebase-ios-swift#4
You then have to click through to Google, then enable, then create a name and select an email before you can hit Save.
It then prompts you to replace the GoogleService-Info.plist file you downloaded earlier in the tutorial.
