Key Reasons Why Swift is the Most Powerful Language for iOS Development

Swift is now the de-facto official programming language for iOS app development. It has been created by Apple, keeping several considerations in mind. When back in 2014, Swift was introduced by Apple as the programming language that would change several paradigms for iOS development and will emerge as the only language to be used by iOS developers. There can hardly be any doubt that the prediction has come true, and Swift did and become what it promises to do and become.

Swift has not just been a success story, but it generated countless success stories and played a crucial role in shaping the dominance of the Apple App Store and the iOS ecosystem in all these years. With every subsequent update, Swift continued to get better and more equipped and will continue to offer more value additions for Swift app developers in the years to come. So, it doesn't need any expertise that the future of iOS development is intertwined with the evolution of Swift.

While Swift will continue to evolve and every Swift update is going to offer us a lot of value additions, it is once again important to understand the key potential of the language. Let us explain some of the reasons that help Swift emerge as the technology driving the future of the iOS platform.

Swift Apps are for the Entire iOS Ecosystem

Swift has emerged as the programming language not just for iPhone apps but for the entire iOS ecosystem that is fast spreading across multiple device platforms comprising the old ones such as iPod, iPad, and MacBook and newer ones such as Apple Watch and Apple TV.

So in the years to come, any new device platform and wearable come out of the factory of Cupertino tech giant, the apps for the devices will be built using the Swift. The best thing is, Swift apps can easily be extended from one device platform to another with little tweaks and value additions.

Interoperable with Objective-C

Objective-C has been the dominant language for all iOS apps before Swift made its resounding entry into the iOS ecosystem. Those old apps that are still loaded with some or many Objective-C files can easily use Swift programming side by side for new features, value additions, redesign, or all sorts of reasons. This becomes possible because Swift allows full access to the API of the Objective-C.

Advanced Language

One of the biggest reasons behind the popularity of Swift is its expressive syntax. Swift's new syntax makes it more flexible, scalable, and versatile for the iOS app projects. Moreover, Swift code is cleaner and secure from potential security threats. This also helps new iOS developers to learn and adapt to Swift programming.
Swift is Open Source

Swift, despite being the next-gen mobile app programming language, remains an open-source language and enjoys the support of a large open-source community of Swift app developers. It is a complete programming language coming equipped with mailing lists, bug trackers, standard development listing, and source code. Moreover, to help developers using Linux, Swift offers a Linux version loaded with Linux tools as well.

Swift is Full of Resources

Swift, as a programming language, offers a large repository of resources for handling all development tasks. Some of the key resources that Swift language is equipped with include Swift Sandbox for learning the language from scratch.

In GitHub, Swift Medium articles and resources, the Visual Studio Code source code editor with inputs from developers all over the globe and a multitude of online resources and books.

Swift code looks similar to the general English language when we compare it with the code of other high-performance programming languages. This makes Swift a better language for fast adoption and easy learning. If any developer has expertise with Java, C++, JavaScript, and Python, he can add value by learning Swift programming with no big learning curve to handle.

Swift Playgrounds

Swift Playgrounds is a great tool from the makers of Swift that helps professional iOS developers experiment with different graphic elements and algorithms before deciding to use them in their apps. The inline code execution facilitated by Apple further helps the programmers experiment, create new code, and get quick feedback on them.

Code Safety

Swift is also popular for its approach to enhance the safety of the code by removing the entire clusters of unsafe code. To ensure the safety of the code, Swift ensures that the integers are routinely evaluated to prevent overflow, and the variables are not given a free run and initialized first. Swift also makes sure that the memory management is done automatically to prevent code leaks.

Faster Error Detection

Swift is also great for reducing coding errors. In Swift programming, the objects can never have a zero value. This ensures that as soon as bad code is written, a compiler error is brought to the developers notice. This helps in fixing problems and issues while programming continues.


Swift has come as a revolutionary programming language transforming many coding practices and development paradigms in the iOS development space. With the kind of promise Swift has already shown and continues to show with every subsequent update, the future of iOS development will take twists and turns along with the evolution of the Swift language.
