Objective-C: Learning Path & Resources.

Introduction: Objective-C is a high-level programming language that is primarily used for developing applications for Apple’s platforms, including iOS, macOS, watchOS and tvOS. It is an object-oriented language that is built on top of the C language and adds features such as dynamic binding and message passing.

Prerequisites: Before learning Objective-C, you should have a basic understanding of programming concepts such as variables, functions and control structures. Familiarity with C programming language is also helpful.

Step-by-Step Learning Path:

  1. Learn the basics of C programming language, including variables, data types and control structures.
  2. Learn about the object-oriented programming concepts such as classes, objects and inheritance.
  3. Learn how to write Objective-C syntax and build basic applications using the language.
  4. Learn how to use Objective-C to build iOS and macOS applications, including frameworks such as UIKit and AppKit.
  5. Learn how to work with databases and perform basic data manipulation.
  6. Practice building real-world projects to apply your skills.

What to Learn Next: After learning Objective-C, you can explore related fields such as mobile app development, game development and server-side programming. You can also learn more advanced topics such as Swift, which is the newer primary language for developing iOS and macOS applications.

Top Advantages:

  1. Widely Used: Objective-C is widely used for developing applications for Apple’s platforms, making it a valuable skill for app developers.
  2. Dynamic Binding: Objective-C’s dynamic binding allows developers to create flexible and adaptable code that can respond to changing conditions at runtime.
  3. Object-Oriented: Objective-C is an object-oriented language, making it well-suited for building complex applications with large codebases.
  4. Interoperability: Objective-C is interoperable with C and C++, making it easy to use with existing code and libraries.
  5. Memory Management: Objective-C’s reference counting memory management model provides developers with fine-grained control over memory usage.

Top Disadvantages:

  1. Steep Learning Curve: Objective-C can have a steep learning curve for beginners, especially when learning advanced topics such as memory management and dynamic binding.
  2. Limited Ecosystem: Objective-C is primarily used for Apple’s platforms, which can limit its usefulness for developers working in other fields.
  3. Syntax: Objective-C’s syntax can be verbose and difficult to read, which can make it harder to maintain large codebases.
  4. Compatibility: Older versions of Objective-C code may not be compatible with newer versions of the language, which can make it difficult to maintain and update legacy code.
