Reasons Why Swift is the Best Choice for iOS App Development

Technological changes are inevitable and so clinging on using the old technology, programming language or development strategies can make your product or service vulnerable to extinction. Whether you’re an individual developer, a startup or a well-established mobile app development company, you need to update yourself with the trending technologies, programming languages or development methods.

Over recent years, the iOS app development industry is taking over the android app development as it generates more revenue and ensures high-level security, faster, easier and cheaper development cost. Generally, Swift and Objective-C programming languages are used for iOS app development. However, with its innumerable benefits, Swift has overtaken Objective-C rapidly, encouraging every startup or reputable IOS Development Company to choose Swift as its prime programming language for iOS app development.

Swift has a lot of potential for developing modern, interactive, adaptive, responsive and feature-rich iOS applications and this is the main reason that makes Swift better over Objective-C programming language. Envisioning a bright future of Swift programming language, many reputable tech giants like Pandora, Lyft, Asana and more have already started using this language.

Here are some of the key benefits that will help you learn why Swift has become the most preferred programming language for an iOS app developer or an iOS app development company, 

  1. Improved Readability

Swift programming language ensures readability as its codes closely resemble plain English language which makes it easier for the iOS app developers to read, write and comprehend the coding. Swift programming language has a clean syntax, reduced number of code lines, and lenient legacy conventions such as the usage of semi-colons for ending lines and parentheses for conditional expressions. In addition, Swift avoids bracket mess as the methods calls do not reside inside each other as they use a comma-separated list of parameters within parentheses. This simplifies the syntax and makes it easy to read. 

  1. Easy Maintenance 

Objective-C requires the developers to maintain two code files for iOS app development to enhance the build time and efficiency of the code. However, Swift omits the requirement of these two files. Swift comes with the LLVM compiler and XCode that expertly identifies code dependencies to perform incremental builds automatically. This omits the need of separating the header file (table of content) from the implementation file (body). Swift combines these two files into one single file with a (.swift) extension. With this advantage, iOS developers can spend more time on creating app logic and less time in bookkeeping.  

  1. Safer and Secure

In this digital era where users are vulnerable to several cyber threats, developing a safe and secure mobile app is a priority for every Mobile App Development Company Building iOS mobile applications using Objective-C will incur a lot of mistakes, frequent crashes, and problematic circumstances. Swift, on the other hand, prevent these unfortunate situations with its simplified syntax and language constructions. Developers using Swift language for their iOS app development are less likely to make mistakes which subsequently leads to the development of high-quality, safe and secure iOS applications.

  1. Faster and Cheaper

With its easy coding syntax and structure, Swift reduces the overall build time of iOS mobile applications. Its faster algorithm calculations ensure faster development of the application which ultimately reduces the overall project cost.

A sophisticated object sort, for example, in Swift will run 3.9 times faster than in Python. Swift’s peak performance has encouraged Apple to work upon the speed at which Swift can run logic apps.

  1. Efficient Memory Management

As the Automatic Reference Counting (ARC), in Objective-C, only supports object-oriented code & Cocoa Touch APIs, it is the developer’s responsibility to take care of memory management when working with low-level APIs, procedural code, and Core Graphics APIs.

Swift, on the other hand, handles the memory management efficiently through ARC during compile time which consumes less time and human intervention.

  1. Linking of Dynamic Libraries Made Easy

Dynamic libraries are chunks of executable code that are external to an iOS app and can be linked to the app when used. Swift supports dynamic libraries which provides the existing Swift apps with the flexibility to link against any updated versions of Swift programming language in the future. Dynamic libraries are directly uploaded to the memory which reduces the app size and improves performance.

  1. Open-source 

Apple announced Swift as an open-source in 2015. This exposed Swift to the potential to be used by every iOS app development company, or iOS app developer for multiple platforms or backend infrastructure. The main intent of open-sourcing Swift by Apple was to get feedback from its users and make the necessary improvements to ensure that is well-designed and well-structured.

Final Words

With these key benefits and more, Swift will very soon emerge as the dominating programming language to be used in the iOS development industry. The spurred growth of this programming language has encouraged every startup or a well-established iOS app development company to use Swift for the enhanced iOS development process and increase their revenue.
