In the ever-evolving realm of mobile app development, the choice of programming language plays a pivotal role in determining the success and efficiency of your project. For iOS app development, two prominent contenders have been vying for dominance: Objective-C and Swift. While Objective-C has a long-standing history and has been the go-to choice for iOS app development for many years, Swift has emerged as a formidable challenger. In this blog, we’ll delve into the reasons why Swift is often considered superior to Objective-C when it comes to building iOS apps.

Swift is Better Than Objective-C for iOS App

1. Readability and Conciseness

One of the most apparent advantages of Swift over Objective-C is its readability and conciseness. Swift was designed with modern programming practices in mind, making it more intuitive and developer-friendly. Its syntax is clean, resembling natural English, which reduces the chances of coding errors and improves code readability. Objective-C, on the other hand, can be verbose and sometimes cryptic, leading to a steeper learning curve for new developers.

2. Safety First

Swift places a strong emphasis on safety, which is crucial in iOS app development. It introduces features like optionals and type inference, which help catch and prevent common programming errors at compile-time rather than runtime. This proactive approach to error handling significantly reduces the likelihood of crashes, enhancing the overall reliability of your iOS apps. Objective-C, being a dynamically typed language, lacks these safety features and can be more error-prone.

3. Performance Boost

Swift is designed to be faster and more efficient than Objective-C. It benefits from a modern compiler and runtime, which optimize the code’s execution. Swift’s performance improvements are particularly noticeable in computationally intensive tasks and can result in a smoother user experience. Objective-C, with its legacy roots, may not be as performant in comparison.

4. Interoperability with Objective-C

While Swift is the newer language, it doesn’t leave Objective-C developers high and dry. Apple ensured seamless interoperability between Swift and Objective-C, allowing developers to use both languages within the same project. This feature enables gradual migration from Objective-C to Swift, ensuring that legacy code can be integrated into new projects without major disruptions.

5. Open Source and Community-Driven

Swift’s open-source nature has fostered a vibrant community of developers, resulting in a wealth of resources, libraries, and tools. This rich ecosystem can significantly accelerate iOS app development, providing readily available solutions to common problems. Objective-C, while still actively used, doesn’t enjoy the same level of community support and innovation as Swift.

6. Less Boilerplate Code

Swift reduces the need for boilerplate code, which can be a common source of bugs and maintenance headaches. Features like type inference, generics, and automatic memory management simplify code, making it more concise and expressive. This streamlined coding approach can save development time and reduce the likelihood of introducing errors.

7. Enhanced Debugging and Testing

Swift’s advanced debugging capabilities make it easier to identify and resolve issues during development. Xcode, Apple’s integrated development environment (IDE), offers robust support for Swift, including features like Playgrounds, which allow developers to experiment with code interactively. These tools contribute to a more efficient debugging and testing process compared to Objective-C.

8. Modern Language Features

Swift introduces modern language features that align with current programming trends. Functional programming constructs, such as map, filter, and reduce, are seamlessly integrated into Swift, making it well-suited for handling data transformations and manipulations. Objective-C lacks these features and may require more code to achieve the same results.

9. Future-Proofing Your Apps

As Apple continues to invest in and promote Swift, it’s clear that the language represents the future of iOS app development. By choosing Swift today, you’re future-proofing your apps, ensuring that they remain compatible with upcoming iOS updates and technologies. Objective-C may eventually become obsolete as Swift adoption continues to rise.

10. Community Preference and Industry Trends

Swift has gained immense popularity within the iOS development community and is often the preferred choice for new projects. As a result, many job opportunities and industry trends are leaning toward Swift proficiency. Choosing Swift for iOS app development can open up more career prospects and networking opportunities in the long run.


In the dynamic world of iOS app development, Swift has proven to be a worthy successor to Objective-C. Its readability, safety features, and performance improvements make it a compelling choice for both new and experienced developers. While Objective-C still has its place in the iOS ecosystem, Swift’s modernity, strong community support, and alignment with industry trends position it as the language of the future. So, if you’re embarking on an iOS app development journey, Swift is undoubtedly the language to learn and master.

Incorporating Swift into your iOS app development toolkit can set you on a path to creating more efficient, reliable, and future-proof applications. Embrace the power of Swift and stay ahead in the ever-evolving world of iOS development.

Remember, the choice between Swift and Objective-C ultimately depends on your specific project requirements and team expertise. However, Swift’s numerous advantages make it a compelling choice for most iOS app development endeavors.

So, whether you’re a seasoned iOS developer or just starting your journey, consider Swift as your go-to language for crafting innovative and exceptional iOS applications.
