Did you know?
📱 Objective-C is a general-purpose, object-oriented programming language used primarily for macOS and iOS development.
💻 It was created in the early 1980s and is a superset of the C programming language.
🛠️ Objective-C features dynamic typing and dynamic binding, which adds flexibility to the programming experience.
📚 The language uses a messaging syntax similar to Smalltalk, allowing methods to be called on objects dynamically.
🖥️ Objective-C worked as the main language for Apple software development until it was largely supplanted by Swift in 2014.
☕ A unique aspect of Objective-C is the use of 'categories' that allow you to add methods to existing classes.
🔗 Objective-C supports multiple inheritance through a mechanism known as protocols.
🎨 Its naming conventions, while often considered verbose, help to improve code readability.
⚙️ The language seamlessly interoperates with C and C++ code, allowing for a more versatile codebase.
🌐 Objective-C code is typically compiled using Apple's LLVM compiler, which offers modern features and optimizations.
Introduction
If you've ever played a game or used an app, there's a good chance it was made using a language like Objective-C. It’s a great way to tell computers what to do! 💻
Objective-c Vs. Swift
Swift was introduced in 2014 as a younger, faster alternative to Objective-C. Swift has easier syntax, which can help new programmers learn more quickly! 🥳
However, Objective-C has a lot of libraries and frameworks that developers can use, making both languages useful! So, while Swift is like a shiny new bicycle, Objective-C is like a classic bike with a great history. Both can take you on amazing journeys in the world of programming! 🚴

History Of Objective-c
This is why so many popular apps today are built with Objective-C! So when you use your favorite Apple gadgets, you are experiencing the magic of this programming language!
Key Features Of Objective-c
One great feature is "dynamic typing," which means the programmer can change data types while the app runs! This makes it really flexible! Another cool feature is "message sending," which allows objects to communicate with each other. 📱
It's sort of like sending texts! Objective-C also uses "classes" and "objects" which help organize code into easier-to-handle pieces. This makes it simpler to create many apps! Plus, its syntax is designed to read like English, making it easier for new programmers to learn! 📚
Getting Started With Objective-c
First, you’ll need a computer with Apple’s Xcode installed. Xcode is a tool for creating apps and programming! After that, learn some basic commands like how to create classes and use methods. You can also find fun online tutorials and videos to help you. 📺
There are great resources like Code.org that can teach you how to code in a fun way! Most importantly, practice is key! The more you code, the better you'll get! Soon, you could be creating your own cool apps! 🚀
Memory Management In Objective-c
In programming, this is important because the computer needs to remember what it needs to run applications. Objective-C uses something called "Automatic Reference Counting" or ARC for short. ARC helps manage memory automatically, so programmers don’t have to worry about forgetting objects! 🎈
This makes coding easier and ensures your device runs smoothly without running out of memory!
Objective-c Syntax And Semantics
In Objective-C, you might see things like "@" and brackets. For example, if you want to create a "car" element, you might write `@interface Car`. This tells the computer that you’re talking about a car! 🌈
The semantics of a programming language means what the code actually means. For instance, if you ask the car to "drive," it should move forward. Objective-C helps programmers create clear instructions so the computer understands what to do! 🚗
Popular Frameworks Using Objective-c
Frameworks are like toolkits that help developers create apps more easily. A popular one is UIKit, which helps build user interfaces for iOS apps. Another is Foundation, which provides basic classes and features for all Objective-C applications. 🏗
️ There's also CoreData, which helps manage data storage. Many famous apps like Instagram and WhatsApp used these frameworks when they were first created! So, when you’re enjoying an app, remember that Objective-C helped build it! 📱
Object-oriented Programming In Objective-c
In OOP, objects represent real-world things like cars, dogs, or even your favorite video games! In Objective-C, we create "classes" to define what these objects are, and then we create "instances" of those classes to use them. For example, if you have a class called Dog, you can create an instance named Fido. 🐶
OOP makes coding easier by allowing programmers to create and reuse code in a fun way!
