By completing this course, learners will be able to apply reactive programming concepts using RxSwift, build dynamic e-commerce user interfaces, manage shared application state, and implement secure, real-time payment validation in iOS apps.

This course provides a practical, end-to-end learning experience for iOS developers who want to move beyond basic Swift and master reactive programming with RxSwift and RxCocoa. Learners will build a complete e-commerce application step by step, starting with product listing and cart management, and progressing through checkout flows, order confirmation, and credit card validation. Throughout the course, learners gain hands-on experience with observables, operators, reactive UI binding, table view integration, Singleton-based state management, and secure payment validation techniques. The course emphasizes real-world application architecture, not just isolated code examples. What makes this course unique is its project-driven approach combined with reactive best practices, allowing learners to understand why and how RxSwift improves scalability, maintainability, and user experience in modern iOS apps. By the end of the course, learners will be confident in designing reactive, production-ready iOS applications suitable for professional development environments.
