Build a Real-Time Chat App with iOS 13, Swift 5 & Firestore

About Course

Course Overview: Dive into the exciting world of iOS app development by building a fully functional, real-time chat application from scratch. This comprehensive course will guide you through using the latest iOS 13 features and Swift 5 programming language, combined with Google’s powerful cloud-based NoSQL database, Cloud Firestore. You’ll learn to craft a beautiful user interface, implement real-time messaging, handle user authentication, and manage data efficiently, culminating in a robust chat app ready for deployment.

Target Audience:

• Intermediate iOS developers looking to build real-time applications.

• Developers interested in integrating Firebase/Firestore into their iOS projects.

• Anyone wanting to enhance their Swift 5 and iOS 13 development skills.

• Aspiring app entrepreneurs with an idea for a chat-based application.

Prerequisites:

• Basic to intermediate knowledge of Swift programming.

• Familiarity with Xcode and the iOS development environment.

• Understanding of basic UI elements (Table Views, Text Fields, Buttons).

• A Mac computer running macOS with Xcode 11 (or later) installed.

• An active Apple Developer account (recommended for full features but not strictly required for development).

Learning Outcomes: Upon completion of this course, students will be able to:

• Master Swift 5 fundamentals in the context of building a complex application.

• Navigate and utilize Xcode 11+ for efficient iOS development.

• Design and implement a modern chat UI using Storyboards and programmatically.

• Integrate Firebase into an iOS project for authentication and database services.

• Implement user authentication (registration, login, logout) using Firebase Auth.

• Send and receive real-time messages using Cloud Firestore.

• Structure and query data effectively within a Firestore database.

• Handle UI updates dynamically as new messages arrive or data changes.

• Manage user sessions and persistence.

• Implement secure coding practices for client-server communication.

• Prepare an iOS application for potential deployment.
