Build a SwiftUI chat app with Firestore from scratch

День тому

💬 Build a chat application with real-time updates from scratch in SwiftUI, with Firebase Firestore
In this tutorial, you'll learn how to code all the components required that make up the chat view, create and configure a Firebase project, connect Firebase to the app, and read from and write to Firestore, with real-time updates - meaning the chat conversation will be updated instantly when a new message is added to Firestore.

Your tutorial has been so incredibly helpful for a new Swift developer. Thank you so much! So concise!

@rendem8168 Рік тому

You’ve made it look so easy, this is something I can actually try and recreate. You showed where everything is coming from. I hope you have a part 2 for the receiver to message back and also to have a group chat.

@@DesignCodeTeam ask Stephanie why she didn't use the keyboard on the simulator for viewers to see the messages animate up .....something tells me because it wouldn't work and that's why it was added in Firestore manually

@muratkul7377 Рік тому

Good tutorial and I have learned quite a few things, thank you. On the other hand this is only the half of the story, you could go ahead and show a list of messages, how to manage 'received' in real life (cause what happens when the other person recieves the message), how to stop listening the snapshot and create a new listener for another chat etc...

Easiest tutorial I've seen on this topic. The next logical step would be a tutorial on how to add users and text specific users...please.

@DesignCodeTeam 2 роки тому

Hi! For that, I suggest you to change the structure of your Firestore database a bit. First, create a collection called "users" and, under each user, you'll have another collection called "messages". This way, the messages will be saved under the corresponding user and you'll be able to map through the users and their specific messages. Hope this helps! - Stephanie

@DesignCodeTeam 2 роки тому

Hi Emmanuel, I'd suggest you to create a collection in Firestore called "chatrooms" and, under each chatroom, create a "messages" collection. That way, you can iterate over the chatrooms in your SwiftUI app and, for each chat, display the corresponding messages. - Stephanie

I have been trying to learn SwiftUi for almost 2 years self taught. I come from no background in this field, I am an interior designer by trade but I have a dream. I have been close to giving up on myself after Covid took a part of my brain… I have been stumbling trying to find the next lesson but I pray and have faith. You know the odds of finding a female programmer…. And then one with this same name?? I’m energized to start this journey with you today and am so glad you put it out there. I’m naive in so many ways, for instance if I have a ? Do I put it here for everyone to see? I haven’t really used UKposts ( I know that’s crazy…I’m 50 lol).

@juliancowell891 Рік тому

Please never give up. I think sometimes videos can be difficult to learn from. It might be useful to find written resources as well to supplement UKposts tutorials.

@tarun_reddy 2 роки тому

Do we need to be aware of the addSnapListener and turn it off when we’re not using it? Ive read some people stressing that.

@juliapp2528 2 роки тому

hey, i'm getting the error in the catch block and I cant figure out why? I have everything set up right. do you know what could possibly throw that error? Thanks

@zenki9862 7 місяців тому

Is there any performance concerns? The message array is sorted every time when there’s an update from the firebase. The demo is using a scroll view instead of a list view meaning cells are not reused.

@fatiherdogan3838 6 місяців тому

I would not use the swift sorting algorithms for this case. You can get the data sorted from firebase directly. Let firebase does the job.

@user-mk6or1gi7v 10 місяців тому

I want to create a simple app where the messages pop up. I finished the MessageField, Messagebubble, and TitleRow. How do I let the chat bubbles post during the scroll?

@octopro8937 Рік тому

Hello DesignCode, I have a question. So basically the place where you type what you want to send the "Enter message here" thing, the background is black (I'm using dark mode) when I switch dark mode off it becomes white (it's not the rounded box that says "Enter message here" it is the background behind that which is a rectangle

@josuesaavedra6175 Рік тому

If you are using a custom color that you created when you created it there is an option to make it sensitive and change depending on dark mode and light mode or you can set it to universal. If you do not want the background color to change, you can set the custom color to universal.

@monnydhingra6369 Рік тому

how to run this on two different simulators?

@stephaniewagstaff6563 2 роки тому

I really enjoyed this tutorial but about 30 minutes in when we started coding with firestore in Xcode and so many words that I had never heard before were used without explanation left me so lost. I only say this to let you know not to be critical, because I was really enjoying the lecture and would’ve loved hearing your explanations because I think I would’ve understood you.

Wonderful but is it possible to have a tuto on how to make a comment via firebase?

Hi! Glad you enjoyed the video! If you want to save comments in Firestore, you can just create a collection called "comments" and follow the same logic as described in this tutorial to get real-time updates from Firestore. - Stephanie

Hi Stephanie, My project requirement is User can post the name once in every 30 minutes in SwiftUI, how to achieve that functionality ?

@DesignCodeTeam 2 роки тому

Hi Mark, I suggest you set up a timer (see developer.apple.com/documentation/foundation/timer or www.hackingwithswift.com/quick-start/swiftui/how-to-use-a-timer-with-swiftui) and once the time has run out, you can unlock the possibility to add a new name. - Stephanie

its very helpful but i am unable to update scroll to id mean scroll is not moving to bottom while opening chat its working perfect during typing msgs but not working at open chat.....

@30guarino Рік тому

I'm working on that as well....

@30guarino Рік тому

Got it!! ...So underneath the .onChange modifier....put .onAppear { messageManager.getMessages }

@scardera Рік тому

Its a great tutorial but your lacking codes. Sarah will see the result as you see it since messages are stored as a received true/false of your point of view.
