RChat – A Chat app built with SwiftUI and Realm

RChat is a chat application. Members of a chat room share messages, photos, location, and presence information with each other. The initial version is an iOS (Swift & SwiftUI) app, but we will use the same data model and backend Realm application to build an Android version in the future.

Read about the Realm data architecture here and how the app was built here.

Building and running the app

1. If you don't already have one, create a MongoDB Atlas Cluster, keeping the default name of Cluster0.
2. Install the Realm CLI and create an API key pair.
3. Download the repo and install the Realm app:

git clone https://github.com/ClusterDB/RChat.git
cd RChat/RChat-Realm/RChat
realm-cli login --api-key <your new public key> --private-api-key <your new private key>
realm-cli import # Then answer prompts, naming the app RChat

4. From the Atlas UI, click on the Realm logo and you will see the RChat app. Open it and copy the App Id

5. (Optional) Use mongoimport to import the empty database from the dump folder to create database indexes
6. Open the iOS project

cd ../../RChat-iOS
open RChat.xcodeproj

7. Update RChatApp.swift with your Realm App Id and then build
