Objective-C vs Swift: The war for iOS development supremacy

You code with the specific type to use for defining a variable in the code. The language is relatively younger; hence the platform is compatible with many other existing technologies. It comes with a complex syntax with problems like Block Syntax.

Advantages of Swift over Objective-C

While Objective-C still holds the crown, Swift is quickly mobilizing to rule iOS development. Let’s examine and compare the most compelling features of each language. If you launch an app on the app store, and no one downloads it, does it even exist? That’s the 21st-century zen riddle of the modern-day app developer.

The developers are also raving about the functionalities of Swift, which indicates that this is a language that deserves all the attention. Swift programming language is open source, which means it was built by both Apple developers and the open-source community. In the early years of Swift’s ios swift vs objective c release, it could already support Linux in addition to all of Apple’s platforms. According to Statista, below is a chart that showcases the most popular programming languages. We have a large team of iOS developers skilled in both Swift and Obj-C, though most prefer to work with Swift.


The CometChat team recently exhibited at Convergence 2022, India’s largest technology and infrastructure expo. What a tremendous opportunity to finally be back in person for our first event of 2022. It’s clear that Swift is the future of iOS and MacOS programming, and while Objective-C is still relevant, it will continue to die a slow death.

Swift developers can also integrate with server-side frameworks like Vapor and Kitura, or machine learning platforms like TensorFlow. Finally, SwiftUI offers a declarative syntax that works well within the Xcode IDE. Swift’s support for dynamic libraries also increases scalability and performance. This feature allows you to dynamically load in external libraries where needed, which decreases your initial app size and speeds up the loading time of external libraries.

Maintenance remains to be complex with Objective-C compared to Swift. On the other hand, with Swift, maintenance becomes hassle-free. However, most of the reports claim that both have a slight difference in speed.

Interestingly, it is using popular programming languages to build applications. Moreover, Apple managed to create an efficient language Swift to eliminate some of Objective-C’s drawbacks. Swift has evolved to support the iOS developers to build app efficiently.

Android vs iOS App Development | Which to choose in 2019?

We have talented developers ready to onboard your project in the best budget for you. You can also alternatively contact us at with your requirements. We have talented, seasoned and professional developers ready to take on any challenge for development. While many existing apps written in Objective-C and maintained and this means Objective-C will not become obsolete any time soon. Apple’s existing APIs require a bit of code adaptation in order to work with Swift. Xcode updates have caused this to change along with newer releases as well.

Dynamic libraries are linkable to a program during run-time, and the shared code that is loaded can be utilized by a large number of programs. This allows developers to update, change, and recompile the code without having to recompile the entire application. On the other hand, Swift’s easy to read and write syntax is driving its popularity in the iPhone app development world. Type safety in Swift helps developers write code more efficiently and error-free through real-time troubleshooting of the assigned types, such as string, integer, and so on. Thanks to type-safety support in Swift, developers can focus on solving actual problems instead of dedicating most of their time to checking code. Like Objective-C, Swift is mostly based on the C coding language.

It prevents integers from overflowing their allotted memory. Now, clearly, it’s unfair to compare this to a non-optimized Objective-C recursive Fibonacci function, because this will leave it in the dust. I’m not even sure I agree with all of the WWDC’s conclusions regarding the merits of the Swift generic memoize implementation. Sure it works great for minimizing repetitive code, but when I executed this method over 1 million Int objects, it took roughly 32 seconds to finish. As oppose to the non-generic implementation, which only took 0.181 seconds. The blockchain ecosystem is wrapped around the idea of decentralized finance.

However, the main concern of the users of Swift is that Swift does not seem to provide anything comparable to Objective-C solutions. You also need fewer code strings in Swift, and it resembles natural English statements, just like many other higher-level programming languages. Objective-C has an inherent complex code structure since it’s built on top of the C language. It includes a lot of different symbols, lines, parentheses, conditionals, and semicolons.

When Do You Choose Objective-C or Swift?

Swift is expected to hold all Apple devices owing to its persistent nature. It has obviously outshined Objective C. Development tendencies change swiftly, so everybody involved is aware of the updates. The upcoming will certainly be a year that will witness iOS app creation extending into new dimensions and conveying a lot more novelties to the industry. To pick one between the two you might need to look at various aspects of both Objective C and Swift. However, Apple was working to meet the real and would-be requirements of technical evolution. Next, Apple introduced Swift in 2014 that changed the development scenario.

  • Like Objective-C, Swift is mostly based on the C coding language.
  • There is an abundance of open-source code, libraries, documentation, and tutorials available for the language, while performance is time-tested and stable.
  • It is a relatively newer language so you have to let go of your previous teachings and shift to the language and its construct.
  • If you want to develop software that will be supported both on devices running modern iOS and macOS versions and those running older versions, there is hardly a better choice than Obj-C.
  • Swift grew in popularity very swiftly , and big companies such as Google, Facebook, Medium, and LinkedIn quickly migrated to using Swift for their iOS apps.
  • Although both Swift and C++ are object-oriented programming languages, the two excel in different areas.
  • Mobile app development company, we specialize in developing an app with both Swift as well as Objective-C.

When comparing the Objective-C it is also worth considering what we mean by Objective-C. You can write C functions in Objective-C code and they will result in code as fast as C. However if you are comparing with C code it will usually be the case that Swift will be slower at the moment. Objective-C uses the static library, and that is another pitiful disadvantage. These libraries linked at the final step of the compilation process after the program is placed into memory. Because of the Static libraries, if any changes applied to external files, it needs to recompile the executable file.

Similarities and Differences

Swift is a modern programming language similar to its peers like JavaScript, Python, and C#. Therefore, modern-day developers find it really simple to work with it compared to Objective C. The main difference between Objective-C and Swift is that Objective-C is relatively easier to learn as compared to Swift. Also, Objective-C has been around for 32 years now, and a wide majority of developers have learned it to its core. However, I wouldn’t recommend Objective-C for complex projects, even with that said. Swift is a continuously-improving language, so it is always optimized to offer the best and most advanced features and functionalities.

What Is Swift?

Objective-C has been existing for over 30 years and the last released its version 2.0, 5 years back in 2016. Surely, it is highly stable but we all know about the bugs we counter while developing an app with Objective-c. And I can easily put my faith in this statement as it is a new language with the purpose to be swift. Swift is also developed from Apple to appeal to new programmers because it is similar to languages such as Ruby and Python than it is Objective-C. An alternative is to hire dedicated iOS developers or outsource your project. So no doubt, this is the language you need to build your new app.

In development, the usage of special string tokens like %s is needed, and developers have to provide a list of variables to replace each of the tokens individually. Maintaining and updating a verbose string of code takes more time, and finding bugs is more complicated. Updating apps and maintaining them is easier if you have clean and concise code and this is where Objective-C and Swift differ from one another. When using Swift, if developers miss a pointer within the code, such as a nil value, the application will crash. Null pointers result in very complex problems for developers. While it does give them higher access to the data, calling a method with nil pointer results in nothing really happening.

In 2020, Swift entered the top ten most in-demand programming languages. For more than a year and a half, he kept his project secret, developing it in his free time. Then Lattner decided to share his invention with Apple’s senior management, who highly appreciated the idea. After that, Lattner got a couple of developers to help him officially continue work on the project. Further, to optimize the memory management Swift employs ARV .

With this detailed comparison guide, here we are not aiming to declare any winner. Both languages are powerful enough to build iOS applications and have their own limitations and benefits. But the choice of programming language is vary depending upon the requirement of your app type.

Stack Overflow Developer Survey 2020, Swift leads the race in the most loved language compared to Objective-C. On the other hand, some people would go with the language they feel more comfortable with or the one they learned first.
