About this Course

Objective-C is a general-purpose, object-oriented programming language that adds Smalltalk-style messaging to C. It is the primary language for legacy iOS and macOS applications and provides access to powerful Cocoa and Cocoa Touch frameworks.

This guide covers Objective-C syntax, classes, categories, protocols, memory management with ARC, dynamic messaging, blocks, Grand Central Dispatch, Foundation and UIKit frameworks, bridging with Swift, debugging, and performance optimization.

Whether you're maintaining legacy code or integrating Objective-C with Swift, these notes provide a thorough reference for professional Objective-C development.
