Hey Brian, I am wondering what the big differences are between the Realtime Database and Cloud Firestore. Which one is better for bigger apps with a lot of users? Also, I currently use the Realtime Database for one of my apps and I want to use Cloud Firestore but I was wondering if there was any easy way to move existing data from the Realtime Database to Cloud Firestore. Thanks!

Hi Brian, I have been following along the tinder videos and I like the new Firestore datebase. I was wondering if it would be possible to follow along the Instagram videos while attempting to use Firestore rather than RTDB. Would that be possible or would it be too hard to follow.

Hi Brian, which mode(locked/test) to select while we setting up the fire store?

Hi, why are all the images being download in .dms file?

If you live in a country which blocks all or part (Database) of Firebase, you will need to use a VPN which supports OpenVPN stealth mode. Basically, this uses https to hide the packet contents. The symptom may be that the Firebase call never returns to your app.

That video was fire!

Go in Database -> Rules -> Change allow read, write: if false; to true;

I'm not admitting to anything, but be careful with code completion when choosing "saveInfoToFirestore" that you don't enter "saveInfoToFirebase", especially within the "saveInfoToFirebase" function. If you do, your app will happily run in the background, silently creating an endless number of images on your Firebase instance.

For what it's worth, I'm using the latest (as of 2/21/19) versions of the pods, and I didn't get the warning that Brian talks about at the end.

Hey Brian - Total nit but you're messing with my OCD dude. Every time I finish a video the web page says 93%, 98%, 96% completed. You'd be shocked how many times I've reopened a video just to fast forward to the end and try to make it set at 100% Man I've got issues...

Hi! I got the following error: "firestore Missing or insufficient permissions." To fix it in the database rules section, you need to modify the false to true: service cloud.firestore { match /databases/{database}/documents { match /{document=**} { allow read, write: if true; } } } I hope it will help some one the next time:)

completion(nil) show error -> Nil is not compatible with expected argument type 'Error'

[Firebase/Firestore][I-FST000001] Write at users/oxPpMiSxUae11KiQ9cs8XnqMf3z1 failed: Missing or insufficient permissions.

I keep getting a "Failed registration, check server response" if anyone could help with this. I'd be super grateful!!

Hi! Brian I really like your lessons about firestore but you should've let us know the guide for website of firestore first! I spent pretty much time for fixing some problems but it was just things on website. Thank you

Hey Brian, I am not able to see users in my database. I don't see any errors in the log either. My Firebase rules: rules_version = '2'; service cloud.firestore { match /databases/{database}/documents { match /{document=**} { allow read, write: if true; } } }

Another thing that I've noticed after I finished registering my user the call to create a new user is being executed over and over again. It kinda creates an infinite loop.

Hi Brian!! Awesome course so far, thanks for that. I am getting a error in , completion(nil) -> 'nil' is not compatible with expected argument type 'Error' Brian or anyone please help.!

Started getting this error today when I came back to continue the course: UIImagePickerController extension discovery failed with error: (null) It was working fine last week. Any idea what this is?

Hi Brian, The Project Download button is broken. When I've tapped upon it the login screen is appeared instead of downloading page.
