The Fast Track To Networking In Swift: Closures, Memory Leak

Unlock Swift Networking Mastery: Build Fast, Debug Smarter, Code for Big Tech

What you'll learn

Understand the core components of a networking service and how they enable modern apps to communicate with remote servers.

Build and configure robust URLs and use the URLSession API to send and receive data efficiently.

Parse JSON responses seamlessly using the Codable protocol and integrate them into your app's architecture.

Implement CRUD operations (Create, Read, Update, Delete) to manage app resources effectively.

Master closures in networking tasks and understand their impact on asynchronous programming in Swift.

Identify and debug memory issues, including handling strong, weak, and unowned references to prevent leaks and retain cycles.

Create custom errors for enhanced error handling and build custom object models for better data management.

Ensure thread safety and manage shared state in networking services to maintain consistency and reliability across your app.

Requirements

You should have a firm grasp of closure syntax.

You should be knowledgeable about Swift's syntax.
