Learn Objective-C Programming Tutorials Guide

Objective-C is one of the core programming languages used in iOS and macOS app development. Even with the rise of Swift, Objective-C is still widely used in legacy apps, system frameworks, and many professional projects. Learning Objective-C gives you a strong foundation in Apple development and helps you understand how iOS works under the hood ⚙️.

What Is Objective-C? 🤔​

Objective-C is an object-oriented programming language created as a superset of the C language. It adds powerful features like objects, classes, messaging, and dynamic runtime behavior, making it perfect for building Apple applications.
Objective-C was the main language for iOS development before Swift, and many real-world apps still rely on it today.

Why Objective-C still matters:

• Used in millions of existing iOS apps
• Deep integration with Apple frameworks
• Powerful runtime features
• Essential for maintaining legacy projects

If you want to become a professional iOS developer, understanding Objective-C is a big advantage 💡.

Why Learn Objective-C in 2025? 📈​

Some developers think Objective-C is outdated, but that’s not true. Many companies still maintain large Objective-C codebases and actively look for developers who understand it.

Benefits of learning Objective-C:

• Better understanding of iOS internals
• Easier transition between Objective-C and Swift
• Strong job opportunities in legacy app maintenance
• Advanced control over memory and runtime

Learning Objective-C also improves your overall programming mindset, especially if you already know C or C++ 🧠.

Setting Up Objective-C Development Environment 🛠️​

To start coding with Objective-C, you need Apple’s official development tools.
What you need:

• macOS
• Xcode (Apple’s IDE)
• Basic knowledge of programming

Once Xcode is installed, you can create a new Command Line Tool or iOS App project and choose Objective-C as the language.

Objective-C Syntax Basics ✍️​

Objective-C syntax may look strange at first, but it becomes very logical with practice.

Hello World Example​

#import <Foundation/Foundation.h>

int main(int argc, const char * argv[]) {
    @autoreleasepool {
        NSLog(@"Hello, Objective-C World!");
    }
    return 0;
}

Key things to notice:

• #import is used instead of #include
• NSLog is used for output
• @autoreleasepool manages memory

This simple program is your first step into Objective-C development 🎉.

Understanding Classes and Objects 🧩​

Objective-C is fully object-oriented. Everything revolves around classes and objects.

Defining a Class​

@interface Person : NSObject
@property NSString *name;
- (void)sayHello;
@end

Implementing the Class​

@implementation Person
- (void)sayHello {
    NSLog(@"Hello, my name is %@", self.name);
}
@end

Using the Class​

Person *person = [[Person alloc] init];
person.name = @"Alex";
[person sayHello];

This structure is essential for building real iOS apps 📱.

​

Methods and Message Passing 📬​

Unlike other languages, Objective-C uses message passing instead of direct method calls.
Example: [object methodName];
This design allows dynamic behavior at runtime, which is one of Objective-C’s strongest features.

Advantages of message passing:

• Flexible method handling
• Dynamic method resolution
• Powerful runtime manipulation

This concept is very important for advanced iOS development 🔥.

​

Memory Management in Objective-C 🧠​

Memory management is a critical topic in Objective-C.
There are two main systems:

• Manual Reference Counting (MRC)
• Automatic Reference Counting (ARC)

Most modern projects use ARC, which automatically manages memory for you.
Example: NSString *text = [[NSString alloc] initWithString:@"Objective-C"];
With ARC enabled, you don’t need to manually release memory, making development safer and faster ⚡.

​

Working with Frameworks and Libraries 📚​

Objective-C integrates seamlessly with Apple frameworks like:

• Foundation
• UIKit
• CoreData
• AVFoundation

Using these frameworks allows you to build powerful apps with fewer lines of code.
Example: #import <UIKit/UIKit.h>
Framework knowledge is key for professional iOS development 🏗️.

Objective-C vs Swift ⚔️​

Many beginners ask whether they should learn Swift instead. The truth is: both are important.
Objective-C strengths:

• Mature ecosystem
• Runtime flexibility
• Legacy support

Swift strengths:

• Modern syntax
• Faster development
• Safer code

Knowing Objective-C makes learning Swift much easier later on 🔄.
