Description

Introduction

Scalability is a crucial aspect of modern iOS application development, ensuring that apps can handle increased user loads, maintain performance, and adapt to evolving requirements. Swift, Apple’s powerful and efficient programming language, provides robust tools and design patterns to build scalable applications. This course explores key architectural patterns, performance optimization techniques, and best practices for designing scalable iOS applications.

Prerequisites

• Basic knowledge of Swift programming
• Familiarity with iOS development using UIKit or SwiftUI
• Understanding of object-oriented and protocol-oriented programming
• Xcode installed on macOS
