Firebase Firestore: CRUD | Swift 4, Xcode 9

Today we go over CRUD operations (create, read, update, delete) with Firebase's new database, Firestore, using Swift 4. This is a step by step tutorial that will explain what is happening in each line of code so you can grasp the full concept of how to get up and running with Firestore and set it up and a production ready way.

Most modern apps require users to interact with one another, and having a server/databse that can make that happen is very important. Learning how to use Firebase with your iOS app can help you become a full stack developer, thus making you a more valuable employee. It can also be a useful skill to test different techniques outside of your production app by replicating the results of your own server and exploring possibilities.

[sirrealistically]

It's because ur funny and know how to entertain that I learn much faster watching your videos. Much love brother, keep up the good work!

[quietcheetahss]

Oh how I wish I had watched this video much, much sooner...


it was great. Thank you, and keep up the good work. Like seriously, I'm counting on it

[jonathanbecerra]

This vid should have more views, not a lot of people sharing expertise with firestore. Awesome video Kilo.

[afinaray]

that was pretty cool. it worths every second of my one and half hours watching. keep up the good work kyle!

Solid! Cleanest implementation of Firestore CRUD operations that I've seen so far.

[DavidNitzscheBell]

Man, that was a lot to process. Not bored, by any stretch. Brain exploded? Yeah, a little. I love the FIR files/classes you create to consolidate code, etc. Some good ideas in here. Now, I just need to figure out how to implement them in my app, which has a bit more than two fields in `users` and has more collections than just `users`.

Wish me luck.

you are my favorite xcoder keep doing ur thing

[ingongoyama]

YOU KILLED ME WHEN YOU WHISPERED "CODE PASSIONATELY" LOL!!!

[leons]

Got some inspiration from your approach and I think there is some space in the Firebase Codebase to make it easier to do CRUD. After trying out some things I will see if I can improve the Firebase codebase

[jamesclarke]

Your tutorials are so good! Thank you for your effort :)

[baileyconradt]

Fantastic tutorial. Love your coding style!

[DavidNitzscheBell]

For an app that uses User Authentication and then stores profile information (First Name, Last Name, DOB, gender, etc.), I guess you'd include the Auth.auth().currentUserID as a User field in Firestore in order to link the two?

[User-mrti]

Thank you bro I am gonna practice it tomorrow

[danylosluzhynskyi]

Extremly useful video, thank you. Could you make one more about that nerwork layer, that you've said?

[josefsantamaria]

Thanks for a really good video, its to few advanced tutorials out there! Ohh yeaaah oooh yeah

[belafekete]

Hi Kyle!
I like your videos, I've almost learnt everything from them! And I also appreciate you explain everything step by step.
I would like to ask a question: how can I send a message to all of the users, when for e.g. there is something new in the application?

[SaifKmusic]

Hey Kyle, for your future reference, setData is better when you have to map a specific user to a document in your collection.

[sethmerritt]

Hey Kilo..Your tutorials are very helpful to see the whole development process on these topics. The data nesting in Firebase seems different than what I am used to with SQL formats. Are you planning to do a tutorial with nested data in Firebase? Could you show us something maybe with users and their associated 'Sweets' as nested data?

[meepable]

Thanks for posting this video, that clears up lot for me! A question, is it possible to unit test generics? I need to review generics as well.
