Pros & cons of Objective-C

6 Pros of Objective-C

• 1. Wide Range of Library Support: Objective-C benefits from a vast collection of libraries and frameworks, including Apple’s own Cocoa and Cocoa Touch frameworks. These libraries provide developers with ready-made solutions for common tasks, saving them time and effort in the development process.
• 2. Robust Community: Objective-C has a strong and active community of developers who actively contribute to its growth and provide support through forums, tutorials, and open-source projects. This community ensures that developers have access to valuable resources and can easily seek help when facing challenges.
• 3. Compatibility with C: Objective-C is a strict superset of the C programming language, meaning that any existing C code can be seamlessly integrated into Objective-C projects. This compatibility allows developers to leverage their existing C knowledge and codebase while transitioning to Objective-C.
• 4. Dynamic Runtime: Objective-C’s dynamic runtime allows for dynamic method resolution, message forwarding, and other powerful runtime features. This flexibility enables developers to write highly adaptable and extensible code, making it easier to implement changes and additions to their applications.
• 5. Proven Track Record: Objective-C has a long history and has been widely used in the development of successful applications and software products. This track record demonstrates its reliability and stability, making it a trusted choice for many developers.
• 6. Seamless Integration with Swift: Objective-C is fully compatible with Swift, Apple’s modern programming language. This means that developers can seamlessly mix Objective-C and Swift code in the same project, allowing for a smooth transition and enabling the use of both languages’ strengths.

6 Cons of Objective-C

• 1. Steep Learning Curve: Objective-C has a complex syntax with a steep learning curve, especially for developers coming from other programming languages. Its unique syntax and reliance on manual memory management can make it challenging for beginners to grasp initially.
• 2. Manual Memory Management: Unlike some modern programming languages, Objective-C requires manual memory management, where developers are responsible for managing memory allocations and deallocations. This can be error-prone and time-consuming, as developers need to carefully manage memory to avoid memory leaks and crashes.
• 3. Lack of Modern Language Features: Objective-C lacks some of the modern language features found in newer programming languages like Swift. For example, it does not have built-in support for features like optionals, generics, or type inference, which can make the code more verbose and less expressive.
• 4. Limited Tooling and IDE Support: While Objective-C has matured over the years, it still lags behind Swift in terms of tooling and IDE support. Some modern development tools and features are primarily built with Swift in mind, making it less convenient for Objective-C developers.
• 5. Limited Cross-Platform Support: Objective-C is primarily used for developing applications on Apple platforms, such as iOS, macOS, and watchOS. While it is possible to use Objective-C for cross-platform development, it requires additional effort and may not offer the same level of support and compatibility as other cross-platform frameworks.
• 6. Declining Popularity: With the introduction of Swift as Apple’s preferred programming language, the popularity of Objective-C has been declining. This decline may impact the availability of resources, tutorials, and community support dedicated to Objective-C in the future.

Cases when Objective-C does not work

1. When developing for platforms other than Apple: Objective-C is primarily used for developing applications for Apple’s platforms such as macOS, iOS, watchOS, and tvOS. If you are targeting other platforms like Windows, Android, or Linux, Objective-C may not be the most suitable choice. These platforms have their own preferred programming languages and frameworks.
2. When performance is a critical factor: Objective-C, being a dynamic language, incurs some runtime overhead compared to statically-typed languages like C or C++. For performance-critical applications, such as intensive mathematical calculations or real-time systems, using a lower-level language may be more appropriate.
3. When working on memory-constrained devices: Objective-C uses reference counting for memory management through its Automatic Reference Counting (ARC) system. While ARC helps manage memory automatically most of the time, it can still lead to memory leaks or inefficient memory usage in certain situations. In resource-constrained environments, such as embedded systems or IoT devices, a language with more deterministic memory management, like C or C++, may be preferred.
4. When building highly concurrent applications: Objective-C does offer support for multithreading and concurrency through technologies like Grand Central Dispatch (GCD). However, compared to languages specifically designed for concurrency, such as Go or Erlang, Objective-C might not provide the same level of built-in concurrency primitives and scalability.
5. When working with modern UI frameworks: Although Objective-C has been the primary language for developing Apple’s user interfaces, the introduction of Swift as a more modern and expressive language has led to a shift towards using Swift for UI development. Many of Apple’s latest UI frameworks and libraries are optimized for Swift, making it the recommended choice for new UI-centric projects.
