What is Swift?

Swift is an open-source programming language specifically used for iOS, and Linux applications. It was created by Apple back in 2014 and became one of the dominant languages for iOS development soon after. Being an open-source language, Swift has a broad community of developers around it, which adds to its usability. Its syntax is rather straightforward, which prevents a large portion of errors and improves readability.

Why Use Swift?

Open Source

Open Source

Being an open-source language, Swift offers developers a wide variety of tools developed by their peers. Apple realized the benefits of open source programming frameworks and Swift was given to the community soon after its initial release. Since 2015, the platform went a long way and now it is easily the best tool for iOS application development available to the public.



Swift uses quite simple syntax, which makes it easier to write clean and concise lines of code. The simplicity of the code makes it easier for the developers to prevent errors and improve the readability of the code. Though the code might feel a bit strict at times, it is actually quite efficient and simple. Our developers specialize in writing neat and readable code using Swift.

Safety and Security


Swift is built with efficiency in mind, and it really shows because it has quite simple syntax and short lines of code. Well, it is called Swift for a reason, and it is estimated that it is 8x faster than Python, which is quite impressive. If you need to put your project on track really fast, Swift might just be your best option.

Simple Deployment


Right now, Swift is one of the most popular programming languages, and considering how it is specialized for iOS and Linux, it is safe to say that it gets the job done. If you want to develop an app for iPhone or any other iOS device, Swift is the way to go, and partnering with the Swift development agency is your best solution here.

Advantages of Swift Language

Safety & Performance
Dynamic Libraries
Full Stack Potential


As said, Swift is a simple, clear, and precise language with readable syntax. It is easy to read and write and is perfectly concise, which results in fewer code lines to perform certain tasks. It makes the whole backend development process much faster. It takes less time to build iOS mobile apps using Swift, which is why it is a perfect choice for when you need things done fast. Less code equals less time spent writing it, and our developers can write that code quite rapidly.


Swift is an easily scalable language, which makes it future-proof. You can improve your application and extend its functionality whenever you need it, and thanks to the simple and concise codebase, it is quite easy to do. Scaling your app up and down takes little time, especially if you use professional Swift development services at Intersog.

Safety & Performance

As the name suggests, Swift is primarily meant to be, well, swift. Made to outperform the predecessors, Swift actually accomplished that goal quite easily. It was reported to be almost 40% more efficient than Objective-C, and over the years, it has proven its robustness and safety times over. It handles errors pretty well too and allows the developers to instantly detect and fix the bugs. Basically, an experienced developer can write, check, and fix the code on the fly, so it saves tons of time.


One of the benefits of Swift is its interoperability with Objective-C, and since Swift has been initially intended to become a superior version of the latter, we might expect an increasing use of Swift compared to its older counterpart in the nearest future. Whether Swift is going to take over Objective-C entirely or not, the two languages are completely interoperable and can both be used within the same project.

Dynamic Libraries

Dynamic libraries exist outside of your code and load only when necessary, and though it might take a bit longer to reach outside the dynamic library because it’s located on the server side, it is still more efficient than a static library. What it means is that each app built with Swift is much smaller, which decreases the memory footprint of the applications. Of course, static libraries offer certain benefits too, so you can also use static libraries when you code in Swift.

Full Stack Potential

Server-side Swift integrates with the vast majority of the modern backend and frontend technologies. Basically, it allows you to build an application completely from scratch without using third-party integrations. Apple provides full support for Swift apps for all of its many devices including Mac, MacBook, iPad, Apple Watch, iPhone, and Apple TV. As an open-source framework, it offers some apps for Linux and even Windows devices.
