Pros And Cons Of Using Swift Programming Language

In this modern age, smartphones have become an integral part of people’s lives. Individuals and organizations use smartphones for tasks such as scheduling appointments, communicating with loved ones, and even ordering food. It’s no wonder that developers are always looking for new ways to create apps that will make people’s lives easier!

One programming language that has gained popularity in recent years is Swift. Swift is a powerful and easy-to-use programming language created by Apple. It’s designed to work with iOS, one of the most popular mobile operating systems in the world with over 900 million users! In the United States alone, there are more than 114 million iOS users.

While Swift is a great choice for developing new apps, there are some pros and cons that you should keep in mind before deciding to use it for your next project.


What is Swift programming language?

Swift is a powerful and intuitive programming language designed for Apple operating systems. Aside from iOS, it is used for macOS, watchOS, tvOS, and Linux apps. This programming language is designed to work with Apple’s Cocoa and Cocoa Touch frameworks and the large body of existing Objective-C code written for Apple products. 

Swift adopts safe programming patterns and adds modern features to make programming easier, more flexible, and more fun. Swift’s clean slate, backed by the mature and much-loved Cocoa and Cocoa Touch frameworks, makes for an ideal platform for experimentation and innovation.


Who uses Swift programming language?

Swift is used by developers all over the world to create amazing apps for Apple products. Some of the most popular apps written in Swift include Uber, Airbnb, Twitter, and Instagram. Currently, there is a growing demand for hiring Swift developers as Apple products are increasing their market share. Thus, learning how to use Swift is a great way to make yourself more in-demand as a developer. 

Like any other programming language, Swift also has its pros and cons. Many developers find that the pros far outweigh the cons, but it’s still important to be aware of both before choosing Swift for your next project.




1. Fast Development

Swift has a clean and simple syntax. This makes it easy to use and can contribute to faster development. Compared to Objective-C, developers can build similar programs with less code using Swift. It is estimated to be faster than Objective-C by an incredible 40%! Additionally, Swift has an Automatic Reference Counting (ARC) feature that helps manage an app’s memory. This reduces the time that developers need to write code when building a functional app.


2. Better Safety

Although Swift can build apps faster, it does not sacrifice safety. Swift features powerful error handling that helps developers easily prevent, detect, and fix code errors. This feature drastically reduces the time needed to detect and fix bugs.


3. Scalability

Apps built with Swift are highly scalable as the programming language is deemed to be future-proof. Mobile app developers can easily add new features to each app as the technology develops. Apple has also expressed its support for Swift over Objective-C, ensuring its scalability in the coming years.


4. Compatibility with Objective-C

Even though Apple is supporting Swift more these days, Objective-C is still widely used by Apple developers. Another pro of using Swift is its compatibility with Objective-C. You can easily integrate features and elements from both languages to build a single app.




1. Limited Backward Compatibility

One disadvantage of Swift is its limited backward compatibility. Developers may face problems when building projects designed for older versions of iOS or macOS. These problems may also arise when an updated version of Swift is released at a different timeline compared to the latest iOS version. Although Xcode – Apple’s development environment – has tried resolving the issue, problems can still occur during the development phase.


2. “Young” Language

Compared to other programming languages, Swift is still young. Developed in 2014, Swift still has ways to go to reach the maturity and stability of older languages like Objective-C, which has been around since the 1980s! Although not necessarily a disadvantage, some developers prefer to use more stable languages as they are more familiar with how to resolve code errors in these older programming languages.


3. Small Community

Developers rely on a vibrant community to learn new programming languages, techniques, and skills from fellow developers. A smaller community can make it difficult to find answers to development questions, especially since the language is relatively young. The good news is that the Swift community has been growing rapidly since the language was first released.


Final Word

All in all, Swift is a powerful programming language that is perfect for developing high-quality iOS and macOS apps. While there are some disadvantages to using Swift, these are outweighed by the many benefits that it offers developers. If you’re looking to develop an app for Apple products, learning Swift is a great way to add new skills and make yourself more marketable as a developer.
