Benefits of programming in Swift

Swift is a popular programming language developed by Apple to build applications for iOS, macOS, watchOS, and tvOS platforms. 

It was first introduced in 2014 and has since gained widespread popularity due to its simplicity, safety, and speed. 

Swift has become the preferred choice for many developers as it is a modern, open-source language that is easy to learn and use.

This article will discuss the benefits of programming in Swift and why it is a popular coding language.

Easy to Learn

One of the primary benefits of Swift is its simplicity. The syntax and structure of the language are designed to be easy to read and understand, making it ideal for beginners. Swift also eliminates many of the complexities of programming in other languages, such as manual memory management, which makes it easier to learn and reduces the likelihood of errors.


Swift is a fast and efficient language optimised for performance. Swift apps run faster and use less memory than apps built using other languages. This is especially important for mobile apps, where performance and battery life are critical. The compiler is designed to optimise code and generate highly optimised machine code.


Swift is designed with safety in mind. It is a type-safe language, preventing common programming errors, such as null pointer exceptions and type-casting errors. This helps to eliminate crashes and bugs, making it a more reliable language for building software.


Swift is an open-source language that is free to use, modify, and distribute. This has led to a large and active community of developers contributing to its development and sharing their knowledge and expertise. The open-source nature of Swift also means that it can be used on a wide range of platforms, including Linux and Windows.

Compatibility with Objective-C

Swift is compatible with Objective-C, the programming language used to develop iOS and macOS apps before Swift was introduced. This means that developers can use both languages together, allowing them to leverage existing Objective-C libraries and frameworks while still taking advantage of the benefits of Swift. This also makes it easier to transition from Objective-C to Swift.

Interactive Playgrounds

Swift includes Playgrounds, an interactive coding environment that allows developers to experiment with code and see the results in real time. This makes learning and understanding Swift easier, as developers can see how code works and make changes to it without compiling and running an entire app. Playgrounds are especially useful for learning new concepts, prototyping ideas, and debugging code.

Support for Functional Programming

Swift supports functional programming, a programming paradigm emphasising functions and immutable data. Functional programming can make code easier to read, understand, and maintain, as it avoids side effects and mutable states. Swift's support for functional programming also makes writing concurrent and parallel code easier, which can improve performance in certain situations.

Growing Job Opportunities

As Swift is a popular language for developing iOS, macOS, watchOS, and tvOS apps, there is a growing demand for developers with Swift skills. This means that learning Swift can open up new job opportunities and career paths for developers. According to Glassdoor, the average salary for a Swift developer in the United States is around $110,000 annually.

Apple's Support

As Apple develops Swift, it benefits from its resources and expertise. Apple provides extensive documentation, tutorials, and sample code to help developers learn and use Swift. Apple also actively promotes the use of Swift, meaning it will likely remain a popular language for iOS, macOS, watchOS, and tvOS development for years to come.


Swift is designed to be a future-proof language, which means it is designed to evolve and adapt over time. 

Apple releases new versions of Swift regularly, adding new features and improvements. This ensures that Swift remains up-to-date with the latest trends and technologies, making it a reliable language for developing software that will stand the test of time.

Swift is a popular programming language that offers many benefits to developers. Its simplicity, speed, and safety make it ideal for building iOS, macOS, watchOS, and tvOS apps. Its open-source nature, compatibility with Objective-C, interactive Playgrounds, and support for functional programming makes it a versatile and powerful language that is easy to learn and use. 

Additionally, its growing job opportunities, Apple's support, and future-proof design make it a language that will likely remain popular for years. 

If you're looking to learn a new programming language or build apps for Apple's platforms, Swift is worth considering.
