Swift App
Development Service

In 2014, after six years of working to improve and develop Objective-C, Apple released a new programming language, Swift at the Apple Worldwide Conference for Developers. Unlike Objective-C, Swift is a statically typed language that is not a strict extension of C.

However, Swift supports interaction with both C and Objective-C, including new, useful features for iOS developers.

Zfort Group provides Swift iOS development using our best competencies. Our main goal is to create the most efficient solution that will contribute to the development of your business. We immerse in your project, delving into its goals and objectives. Vast experience and knowledge, as well as the use of cutting-edge technologies, allow us to offer our clients better decisions for Swift mobile app development.


  • Easy Сode

    Swift iOS development is easier than Objective-C. One of the significant benefits is the length of the code required for various kinds of applications. It is easier to study the code, and the time of writing is halved. Moreover, the code allows the use of emoticons.

  • Fast and Efficient

    Apple claims that Swift is up to 2.6 times faster than Objective-C, and 8.4 times faster than Python 2.7. According to the creators, Swift has incorporated the best from other programming languages. Its main advantage is speed: both during the development process and after the ready-made application launch. Hence, for this advantage over other languages, it was called Swift. In addition, Apple is continuously working on Swift speed increase. The fast code works more efficiently and smoothly, allowing a user to enjoy the device’s usage fully.

  • Standardized Syntax

    Swift syntax is short and straightforward. It was created to help developers eliminate common mistakes. The errors’ risk is minimized; it speeds up the work and makes it safer and more comfortable for users. A bonus is that Swift memory is managed automatically.

  • Clean Debugging

    In comparison with Objective-C, Swift is more resistant to miscode, so you could say it is less error-prone. For instance, it enables to generate a compiler error if an iOS application developer writes bad code. That is, the issue can be fixed once the code is written. This feature allows you to save time and money spent on bug fixing.

  • Compatibility with Objective-C

    One of the main features of Swift is its full backward compatibility with Objective-C. Thus, it allows you to rewrite projects from one language to another gradually. Furthermore, an integrated ecosystem has been created for Swift, ensuring code compatibility written in Objective-C and Swift.

  • Playground

    A playground is a kind of interactive sandbox where a developer can write code and immediately see the result of his work, without creating the iPhone app from scratch. This fact speeds up the coding process because separate pieces of code or algorithms can be written in the playground with visual feedback, without the risk of making errors in the main code.

  • Open Source

    Since Swift is open source now, Apple has taken steps towards becoming cross-platform. Designed for Apple platforms, Swift is slowly extending to other platforms. Currently, it’s compatible only with Linux. But it is predicted that this language will become more portable and over time will be available on other platforms.

  • Room for Improvement

    Since the system is quite young, it will be improved in the feature. Swift creators are striving to make their brainchild successful, continually working on new features. The tech giant IBM also has contributed significantly to the development of the language. The company introduced Swift (Sandbox) test environment and made it available in the cloud. Therefore, Swift backend development can be integrated with a large number of server tools.

Once the design is ready and approved, the ball is in the developers’ court, and code development of the mobile application begins.
