What is Objective-C?
Objective-C is a high-level general-purpose object-oriented programming language that adds Smalltalk-style messaging to the C programming language. It was originally developed by Brad Cox and Tom Love in the early 1980s, and later adopted by NeXT for its NeXTSTEP operating system. Apple acquired NeXT in 1996, and since then, Objective-C has been the standard programming language for developing applications for macOS and iOS platforms.
Objective-C inherits the syntax, primitive types, and flow control statements of C, and adds syntax for defining classes, methods, properties, protocols, categories, blocks, and more. It also provides a dynamic runtime that supports dynamic typing, dynamic binding, dynamic loading, reflection, introspection, exception handling, memory management, and other features. Objective-C is compatible with C and C++, meaning that you can use C or C++ code within an Objective-C program.
Why learn Objective-C?
There are many reasons why you might want to learn Objective-C. Here are some of them:
It's powerful. Objective-C gives you access to a rich set of frameworks and libraries that enable you to create complex and sophisticated applications with ease. Some of these frameworks include Cocoa (for macOS), Cocoa Touch (for iOS), Foundation (for basic data types and utilities), UIKit (for user interface components), Core Data (for data persistence), Core Animation (for graphics rendering), Core Location (for geolocation services), Core ML (for machine learning), ARKit (for augmented reality), SceneKit (for 3D graphics), SpriteKit (for 2D games), and many more.
It's popular. Objective-C is one of the most widely used programming languages in the world, especially for developing applications for Apple devices. According to the TIOBE index, Objective-C ranks as the 11th most popular programming language as of June 2021. According to the Stack Overflow Developer Survey 2020, Objective-C ranks as the 19th most loved programming language and the 14th most wanted programming language among developers.
It's lucrative. Objective-C developers are in high demand and can earn a good income. According to Indeed, the average salary for an Objective-C developer in the United States is $108,763 per year as of June 2021. According to Glassdoor, the average salary for an Objective-C developer in the United Kingdom is 47,500 per year as of June 2021.
It's fun. Objective-C is a fun and expressive language that allows you to create amazing applications that can delight and impress your users. You can use Objective-C to create games, animations, simulations, utilities, social media apps, productivity apps, educational apps, entertainment apps, and more.
How to get started with Objective-C?
If you are ready to start learning Objective-C, you will need some prerequisites and tools to set up your development environment. Here are the steps you need to follow:
Installing Xcode
Xcode is the official integrated development environment (IDE) for Objective-C. It provides you with a code editor, a compiler, a debugger, a simulator, a documentation browser, a testing framework, a source control manager, and other tools that make your development process easier and faster. Xcode is available for free from the Mac App Store or from the Apple Developer website.
To install Xcode, you will need a Mac computer running macOS 10.15.4 or later. You will also need an Apple ID to sign in to the Mac App Store or the Apple Developer website. Once you have these requirements, you can follow these steps:
Open the Mac App Store or go to https://developer.apple.com/xcode/.
Search for Xcode or click on the Xcode icon.
Click on the Get button or the Download button.
Wait for Xcode to download and install on your Mac.
Launch Xcode from your Applications folder or from your Launchpad.
Creating a simple Objective-C project
To create your first Objective-C project in Xcode, you can follow these steps:
In Xcode, go to File > New > Project or press Command + Shift + N.
Select macOS > Command Line Tool and click Next.
Enter a name for your project (e.g., HelloObjectiveC) and choose Objective-C as the language. You can leave the other options as default or change them as you wish.
Select a location for your project and click Create.
Xcode will create a new project with a main.m file that contains some boilerplate code. This file is where you will write your Objective-C code.
Exploring the Objective-C syntax
To write your first Objective-C program, you will need to learn some basic syntax rules and conventions. Here are some of them:
Objective-C code consists of statements that end with a semicolon (;).
Objective-C code can include comments that start with // (for single-line comments) or /* and */ (for multi-line comments). Comments are ignored by the compiler and are used to explain or document your code.
Objective-C code can use preprocessor directives that start with # (e.g., #import, #define, #ifdef). Preprocessor directives are instructions for the compiler that are executed before compiling your code.
Objective-C code can use variables to store values of different data types (e.g., int, float, char, NSString). Variables must be declared before they can be used, and they must have a name and a type. Variables can be assigned values using the = operator.
Objective-C code can use operators to perform arithmetic (+, -, *, /), comparison (==, !=, ), logical (&&, , !), bitwise (&, , ^), and other operations on values or variables. Operators have different precedence and associativity rules that determine how they are evaluated in an expression.
on conditions (e.g., if, else, switch, case).
Objective-C code can use functions to group statements that perform a specific task. Functions must have a name, a return type, and a list of parameters. Functions can be defined using the syntax: return_type function_name(parameter_list) statements; . Functions can be called using the syntax: function_name(argument_list);.
Objective-C code can use classes to define new data types that encapsulate data and behavior. Classes must have a name and can have instance variables, properties, methods, and initializers. Classes can be defined using the syntax: @interface ClassName : SuperClassName instance variables; properties; methods; @end. Classes can be implemented using the syntax: @implementation ClassName instance variables; methods; @end.
Objective-C code can use objects to create instances of classes that can store data and execute methods. Objects can be created using the syntax: ClassName *objectName = [[ClassName alloc] init]; or ClassName *objectName = [ClassName new];. Objects can be sent messages using the syntax: [objectName methodName:argument];.
To demonstrate some of these syntax elements, let's write a simple program that prints "Hello, Objective-C!" to the console. You can replace the boilerplate code in your main.m file with the following code:
#import
int main(int argc, const char * argv[]) @autoreleasepool // Declare a string variable NSString *message = @"Hello, Objective-C!"; // Print the message to the console NSLog(@"%@", message); return 0;
To run your program, you can go to Product > Run or press Command + R. You should see the output in the console window at the bottom of Xcode.
