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.
- If you don't already have one, create a MongoDB Atlas Cluster, keeping the default name of

- 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

cd ../../RChat-iOS
