The Swift Programming Language

As now the demand for mobile application development has rapidly increased. According to Statista Reports, “In 2019, over 2 million apps are available for download on the Google Play store, while 1.83 million apps are available on the Apple App Store. Growing mobile application leads to introduce upgraded versions of the programming languages, frameworks, and tools. 

To make the development process easier and faster, Apple has introduced an upgraded version of Objective C, which is known as Swift. As this swift coding language has launched in the market, since then there is a high demand for the iOS Swift App Development Services

Swift –  The Apple Swift Programming Language

Swift is launched by  Apple Inc. in the year 2014 at Worldwide Developers Conference (WWDC). It is a general-purpose, multi-paradigm, compiled programming language. This programming language is supported for iOS, iPadOS, macOS, watchOS, tvOS, Linux, and z/OS. Apple developers designed the Swift programming language to operate with Apple’s Cocoa and Cocoa Touch frameworks.

To meet with the market competition and standard, Apple developers used to upgrade it and launch its modern version constantly with advanced features.

Presently, Swift 5.1 launched in September 2019 and  it includes features that make it easier to design better APIs and reduce the amount of common boilerplate code. Swift is a powerful, modern, and interactive programming language, which helps to develop code easily and supports the Syntax feature.  This language is easy to use. 

Swift coding language is the most preferred choice and offers extensive benefits to the app developers but there are some cons also. In this article,

let’s know both the aspects of the Modern Apple programming language Swift. The good and the bad of Swift programming language.

Pros of Swift Programming Language 

Modern Programing Language 

This is one of the reasons that iOS developers get attracted to this language. Swift is the modern language and integrated with advanced features. It is designed in such a way that it can overcome all the issues that Objective C used to have. Experts have addressed all the major issues that developers use to face in Objective C. 

Open Source 

In 2015, Apple announced Swift as an open-source and garnered technical support from worldwide developers. An open-source feature offers support of an active community to the Swift programming language. Swift is the most structured and upgraded language as developers use to modify it constantly. 

Due open-source feature small, mid and large enterprises can take the full potential of the Swift programming language without any cost. 

Swift is the fastest programming language.  This swift programming language offers 2.6x faster than Objective-C and 8.4x faster than Python. It was designed with the motive to have a high performance in the mobile application.

Easy Coding 

Swift offers easy coding to developers. Mobile app development programmers can easily read and write code with Swift. It requires less coding efforts and like Objective C, its functionalities are not divided into two parts – interface and implementation. In this header file and implementation, the file is combined in one file. With Swift, writing and maintaining code is easy. 

Similar to Objective C 

The best thing about the Swift programming language is its similarity to the most versatile language Objective-C. Developers can easily learn it and only advanced features have been added to this. Programmers can easily use and learn this language without any hurdle if they have worked on Objective C so they will take a short period of time to learn this language. 

Swift also allows mobile app developers to write the code in this language and they can use the same code in other languages.  

These are advantages of Swift mobile application development, but it also has some cons. 

Cons of Swift Programming Language 

New Language 

It is a modern and new language. New language is turning as cons for the mobile app developers to opt for this language. As it is new, so developers are hesitant to opt for this language. Swift is powerful and integrated with modern features but as developers are using it, new challenges are highlighted which may take time to fix also.

Limited Developers 

This is the second challenge to opt for the Swift programming language. As it is a new language so developers are not in the pool. To hire a Swift developer can be a big challenge. The requirement of the Swift mobile app development is rapidly increasing but to hire a Swift developer is the next challenge. 

Lack of Support for Previous Versions 

Swift programming language doesn’t support the previous iOS versions. This can only be integrated with the iOS7 version or later iOS operating systems.  

Poor interoperability with third-party tools 

Nowadays, frameworks and third-party tools play an imperative role in the development process. As frameworks and tools turn the development process into easier and faster, developers prefer to opt for several third-party tools but Swift has Poor interoperability with third-party tools

How to Learn Swift Programming Language? 

As there are limited Swift developers, so there might be some challenges to learn Swift.

Developers can learn the language through:

  • Official Apple Documentation – It is the best place to learn the Swift language as this way developers can learn from the root without any misconception. 
  • World Wide Developer Conference – Every year Apple WorldWide Developer Conference is held. This conference allows experts to announce the updates. 
  • Blogs and Tutorials There are several blogs and tutorials available on digital platforms where developers can get full information. Some popular Swit mobile application blogs are  Ray Wenderlich, AppCoda, and NSHipster.
  • Newsletters –  iOS Dev Weekly, This Week in Swift and Swift Weekly these are several newsletters that provide updates related to the technology. 


This programming language is modern and with Swift app development company mid to large enterprises are leveraging the potential of the Swift programing language. As this is a new language, there are some technical challenges which developers are facing but with time it will replace Objective C and turn as the most preferable language of the iOS app development. Due to its open-source features, several challenges will soon be sorted out.
