About

Welcome to iCode  🎥 Here you’ll find videos on iOS app development, backend engineering, and system design — explained with clarity and real-world examples. iOS Development: Swift, Xcode, UIKit/SwiftUI, live coding, interview prep, and the latest updates from Apple. Backend & System Design: Servers, APIs, databases, caching, scalability, and distributed systems — with deep dives into sharding, replication, consensus algorithms, eventual consistency, and fault tolerance. Learn by Doing: Every video balances theory + implementation, so you not only understand the concept but also see how it’s applied. Whether you’re a mobile developer curious about backend, a software engineer preparing for system design interviews, or someone who simply wants to understand how large-scale systems work — you’ll find practical, in-depth, and engaging content here. 📅 New videos every Sunday.
