However, despite Swift’s rapid adoption, Objective-C remains a vital part of the Apple ecosystem, especially for legacy projects and certain complex applications. In this article, we will compare Objective-C and Swift and explore why you might still need to [hire objective c developers](https://gloriumtech.com/hire-objective-c-developers/). A Brief Overview of Objective-C and Swift Before diving into why you might still need Objective-C developers, let’s take a quick look at both languages. Objective-C: Objective-C is an object-oriented programming language that evolved from C in the 1980s and was heavily influenced by Smalltalk. It became the primary language for developing applications on Apple’s platforms, such as iOS and macOS. The language uses a distinct syntax with a strong focus on message-passing and dynamic typing, which allows for more flexibility in development. Swift: Swift, introduced by Apple in 2014, is a modern, statically typed language designed to replace Objective-C in the long run. It was developed to be fast, type-safe, and easy to use, with features like optionals, closures, and type inference that make coding more intuitive. Swift was designed to be more approachable for new developers while offering a performance boost for seasoned professionals. While Swift has been aggressively promoted by Apple, Objective-C continues to coexist with Swift, with many existing applications still relying on it. This brings us to the question: Why would you still need an Objective-C developer? 1. Legacy Code and Maintenance One of the most compelling reasons to hire Objective-C developers is the maintenance of legacy code. Many companies have built large, complex applications using Objective-C over the years. These applications may not be feasible to rewrite in Swift due to the sheer amount of code, time, and resources required. Cost Efficiency: Rewriting a large application in Swift can be costly and time-consuming. The process involves refactoring the entire codebase, ensuring that all features are maintained, and conducting extensive testing. In many cases, it may not be worth the investment when the existing Objective-C code is still functioning well and meeting business needs. Seamless Updates: Instead of rewriting everything in Swift, businesses can opt to incrementally update their Objective-C codebase. An Objective-C developer can carefully update legacy code while still keeping the application functional. This method ensures that the app continues to run smoothly, while new features can be added using Swift without disrupting the existing codebase. 2. Compatibility with Older iOS Versions While Swift is continuously evolving and bringing new features, Objective-C remains the language that can support older versions of iOS (iOS 7 and earlier). Swift is a modern language, and although it’s backward compatible with iOS 8 and later, it might not be able to take full advantage of features in older operating systems. Backward Compatibility: If your application needs to support older devices or iOS versions, using Objective-C is often a safer bet. Since many older devices may not support the latest iOS updates, sticking with Objective-C ensures that your app will work on these devices. For businesses targeting a wider audience, especially in regions where users may not have upgraded to the latest devices, Objective-C remains crucial. 3. Performance and Low-Level Optimization Although Swift is known for its fast performance, Objective-C offers a certain level of fine-grained control over memory management and optimizations that some specialized applications still rely on. For instance, applications that require complex algorithms or intensive computations may benefit from Objective-C’s mature infrastructure. Custom Optimization: Objective-C allows for custom memory management techniques and low-level optimizations that can make a difference in performance-heavy applications. For example, Objective-C can give developers more control over manual memory management using the retain and release commands, offering potential advantages in terms of performance for certain use cases. Complex Applications: In specific scenarios, such as applications that heavily rely on system-level integrations, file systems, or even real-time processes, Objective-C’s performance can be more predictable. Developers with Objective-C expertise understand the intricacies of memory handling and system resources, which can be a significant advantage in certain high-performance applications. 4. Interoperability with Existing Libraries Another advantage of Objective-C over Swift is its seamless interoperability with numerous libraries and frameworks that were originally written in Objective-C. Many third-party libraries, as well as Apple’s own frameworks, are still written in Objective-C. This means that Objective-C developers are better equipped to work with these libraries and ensure that they are integrated properly into iOS applications. Cocoa and Cocoa Touch Frameworks: Cocoa and Cocoa Touch are the primary frameworks used in macOS and iOS applications, respectively. These frameworks were developed using Objective-C, and while Swift is now fully supported, many legacy features are still written in Objective-C. Having an Objective-C developer on your team ensures you can fully leverage these frameworks and libraries. Third-Party Integrations: Many third-party SDKs, particularly older ones, are written in Objective-C. For businesses that require deep integrations with such libraries, having an Objective-C developer can help ensure smooth compatibility and faster resolution of potential issues. 5. Expertise and Established Knowledge Base Objective-C has been around for decades, and as a result, there is a vast wealth of knowledge and experience among Objective-C developers. These developers have worked with the language since its early days and have a deep understanding of its nuances and limitations. They can bring a unique perspective to your development team, especially when dealing with legacy code or complex application requirements. Problem-Solving: Seasoned Objective-C developers have encountered and solved a wide range of issues that can arise in software development. Their extensive experience allows them to address challenges quickly and efficiently, particularly with older applications that may not be as well-documented or easy to work with. Mentoring and Training: Objective-C developers can also play an essential role in training new developers and helping them navigate the intricacies of iOS development. Their expertise can help teams maintain best practices while transitioning to Swift or working with hybrid applications that use both languages. 6. The Hybrid Approach: Objective-C and Swift Together Many modern applications now use both Objective-C and Swift in tandem, leveraging the strengths of each language. This hybrid approach can be particularly beneficial for teams transitioning from Objective-C to Swift. Swift for New Features: New features and modules can be developed using Swift, taking advantage of its modern syntax and powerful features. This allows businesses to stay up to date with the latest language trends while still maintaining the functionality of their legacy Objective-C code. Objective-C for Legacy Systems: Older features and systems that are already written in Objective-C can continue to be used without major rewrites. This hybrid approach allows developers to strike a balance between using the latest technologies and preserving the stability of legacy systems. 7. The Demand for Objective-C Developers Despite Swift's growing popularity, the demand for Objective-C developers remains strong, particularly in industries and businesses with established iOS applications. Many companies still rely heavily on Objective-C for their core iOS applications, and as such, they need skilled developers who can maintain, update, and optimize these systems. Specialized Skills: Objective-C developers bring specialized skills to the table. Their expertise is invaluable for organizations dealing with legacy codebases or highly complex applications. As Swift continues to mature, Objective-C will likely remain a key skill for certain projects for the foreseeable future. Hiring Objective-C Developers: If your business has an iOS application built in Objective-C or needs to support legacy systems, hiring an Objective-C developer may be necessary to ensure your app’s long-term success. Whether it's for maintaining existing code, optimizing performance, or helping with a gradual migration to Swift, having an experienced Objective-C developer on your team can make all the difference. Conclusion While Swift has become the language of choice for new iOS and macOS applications, Objective-C remains a vital part of the Apple ecosystem. Its longevity, performance capabilities, compatibility with legacy systems, and deep integration with third-party libraries make it an invaluable asset for many businesses. If your organization relies on legacy iOS applications, needs to support older iOS versions, or requires fine-tuned performance optimizations, hiring Objective-C developers can help ensure the continued success of your applications.
