Objective-C is a high-level programming language that was developed by Apple Inc. for use in its macOS and iOS operating systems. Objective-C is an object-oriented language based on the C programming language. It adds object-oriented capabilities to the C language and is the basis for programming on Apple platforms.

Technical Aspects and Capabilities


Objective-C provides capabilities for creating objects and classes, which simplifies code organization and enhances its reusability.

Dynamic Nature

Objective-C has dynamic capabilities, allowing the determination of object types at runtime, rather than at the compilation stage.

Compatibility with C

Objective-C is fully compatible with C, meaning that you can use C code in Objective-C programs without modification.

Powerful Error Handling System

Objective-C has a powerful error handling system, which helps ensure stability and reliability of applications.

Advantages of Objective-C


Due to the fact that Objective-C is based on C, it offers high performance, which is often required for mobile applications.


Objective-C was created in the early 1980s, and over time it has undergone many changes and improvements. This makes it a mature and stable language.

Large code base

There are many libraries and frameworks written in Objective-C, which facilitates the development of applications.

Apple Support

Objective-C is supported by Apple, which guarantees its updates and support in the future.

Complex Syntax

For many developers, especially those accustomed to the syntax of other languages, the syntax of Objective-C may seem complex and non-intuitive.

Aging Language

Objective-C was developed over 30 years ago and, although it has been updated and supported by Apple, it lacks many modern features available in newer languages, such as Swift.

Large Volume of Code

Due to its syntax and object-oriented features, the code in Objective-C often turns out to be longer than in other languages, which makes it less compact and harder to maintain.

Compilation Speed

The compilation speed of Objective-C can be slower compared to some other languages, which can increase development time.

Learning Difficulties

For new developers, it might be difficult to learn Objective-C due to its unique syntax and features. This can increase the time and costs of training new employees.

Objective-C has a long history of use in developing applications for Apple platforms and is still used in many projects. It has its advantages, such as high performance, stability, and support from Apple. However, its complex syntax, relative old age, and other disadvantages make it less attractive for some developers and projects. Modern alternatives, such as Swift, might offer more modern features and a convenient syntax.
