I'm really enjoying learning Firebase rules on KZfaq for the first time. However, it seems like many creators prioritize maximizing their watch time for profit rather than focusing on effective teaching methods. Your 50 minutes video is enough to understand security rule. Thank you 🎉

Finally a tutorial about the security rules. Thank you so much for this. It was very helpful!

Thanks for all the work you do. I always come back to this Firebase series whenever I need a refresher. All your information is always laid out so well and concise!

Thank you so much! I finally understood security rules. I tried before writing these rules and I just got frustrated but now I feel like I got them. You are a great teacher, please continue with these great lessons 🙏🏻

Wow. it is never a boring video from you. New knowledge is always the way to move forward. Thanks a lot!

bro you are a god send!

Thank you so much Nick!!

Nice video 🎉😊

Thanks for the tutorial! It was very helpful :) Quick question... have you ever run into weird issues with writing rules for a collection where there's a listener attached that uses a whereField("uid", isEqualTo: xxxx) clause? For example, Does NOT work -> match /users/{user} { allow read, write: if request.auth != null && request.auth.uid == user; // where {user} is the uid and document ID } Works -> match /users/{user} { allow read, write: if request.auth != null && request.auth.uid == resource.data.uid; //uid just happens to be on document here }

Can you also please make an exclusive playlist about OOP using Swift?

Hi friends, how do you secure realtime database as follows. I have notes product:{ data1: { idMaker: 123abc, .... }, data2: { idMaker: 123abc, .. }, ... } .What I want: all users can set() provided it has child: "name". and only users whose idUser is the same as idMaker can delete. please answer

Hi Nick. Great bootcamp! It took me 20 lessons before encountering the first problem 😀 After introducing the exact same security rules as you did, the app is not working anymore. I can't add favorites (the debugger says "Missing or Insufficient permissions"). If I restore the old rules (match /databases/{database}/documents { match /{document=**} { allow read, write: if request.auth != null;}}} then it works perfectly. Tried also to logout, delete users in DB and restart but no success. I triple/quadruple check and the new rules are exactly the same as yours (I didn't test the app at every step as you did, so not sure at what time it started to go wrong). Any hint?
