What if you could build a native, real-time iOS chat app from scratch in under 45 minutes? This tutorial shows you how.

From Zero to Mobile Developer in 45 Minutes With SwiftUI
#1about 2 minutes

Understanding the core concepts of SwiftUI development

SwiftUI applications are built by composing state-driven views using components like VStack, HStack, and ZStack.

#2about 2 minutes

Using Realm for real-time data synchronization

Realm syncs data between the embedded mobile database and MongoDB Atlas, enabling real-time updates across devices.

#3about 4 minutes

Setting up the Xcode project and dependencies

Start by creating a new SwiftUI app in Xcode and then add the Realm SDK as a dependency using the Swift Package Manager.

#4about 2 minutes

Defining the data model for chat messages

Create a Swift class that inherits from Realm's Object to define the schema for chat messages, including properties and a primary key.

#5about 6 minutes

Implementing anonymous user authentication with Realm

Build a login view that uses Realm's anonymous authentication to log a user in and uses a binding to update the parent view's state.

#6about 3 minutes

Building a navigable list of chat rooms

Use a SwiftUI List and NavigationLink to create a view that displays available chat rooms and navigates to a specific chat view on selection.

#7about 6 minutes

Displaying live messages with ObservedResults

Use the @ObservedResults property wrapper to create a live, auto-updating view of chat messages fetched directly from the local Realm database.

#8about 5 minutes

Sending messages and persisting them to Realm

Implement a function to create a new chat message object and append it to the observed results collection, which automatically persists it to Realm and syncs it.

#9about 1 minute

Verifying real-time sync with MongoDB Atlas

See how creating or modifying a document directly in the MongoDB Atlas cloud UI instantly reflects in the running mobile application.

#10about 2 minutes

Configuring a new backend in MongoDB Cloud

Quickly create and deploy a new serverless backend application for Realm Sync through the MongoDB Cloud UI by defining a partition key.

#11about 8 minutes

Answering audience questions about mobile development

The Q&A session covers topics like Realm's scalability, SwiftUI layout patterns, handling background tasks, and alternatives to Storybook.
