Developed by Apple Inc. in 2014 for building scalable apps on iOS, iPad, macOS, tvOS and Linux, Swift is an open-source multi-paradigm programming language, with a simple and compact syntax, more famously known as the “Objective-C without the C”. Swift is basically a combination of power type interference with an expressive syntax to enable easy code readability and usability. With the introduction of Swift, a fast and safe language became available for the iOS platform consisting of modern features including protocols, closures, generics, optionals and type inference, ensuring app security and safety while making it easier and more flexible to use in comparison to Objective-C

Swift Background

Combined with Cocoa and Cocoa Touch, Swift provides a more enhanced experience of app development, eradicating common programming errors including null pointer dereferencing and providing coding solutions for expressive coding, app safety and performance. It allows memory usage to stay at a minimum using tight, deterministic reference counting. Additional features include flow control, data structures and functions, and compatibility with C libraries and frameworks.

Swift has undergone various upgrades; the current version at the time of this writing, Swift 5.1, was released in 2019. This version increases the stability of the application binary interface (ABI) on Apple platforms, enhancing module stability and binary compatibility to create frameworks which will enable apps to be compatible with all future versions of Swift.

The aim of creating Swift was straightforward; to make programming easy by removing the complexities from coding. Swift is a modern language where developers have the ability to write fewer lines of code while maintaining performance and efficiency similar to that of C++.

Many distinguished tech companies are now moving towards Swift. LinkedIn, a professional social network, now uses Swift in their mobile app. Lyft, a ride-sharing app, has also moved towards Swift for their native iOS app development. Companies like Yahoo, WordPress and Firefox are also choosing Swift over Objective-C for their development.

Benefits of using Swift

Swift has many key benefits giving it an edge over other iOS programming languages:

Open Source

As of 2015, Swift is an open-source programming language and is available for download on Github. Given its open-source nature, it allows for developers to suggest enhancements, contribute to new features and fix bugs.

The Swift community encourages developers all around the world, green and experienced, to contribute to its source code in order to make it more feature-rich and efficient. This involves answering questions on the forums, highlighting ways of making the language more useful, and reporting any bugs that need to be fixed. Find out more on contribution guidelines here:

Code Readability
Code Readability

Considered a programming language which reads more like normal English, Swift is easy to read, write and edit, having a clean and simple syntax. With Swift, fewer lines of code are required to create the application as compared to Objective C, saving developers the hassle of adding conventions like semicolons, end lines and parenthesis. The readability of the language also gives developers with expertise in other languages such as JavaScript, Java, Python and C# the ability to learn and use Swift without too much trouble.

Code Readability

With its feature of automatic memory management (ARC), Swift enables runtime safety to prevent errors during development by enabling initialisation of variables and ensuring access to memory. ARC also aims to reduce memory and increase the performance of the app. On the other hand, Swift rejects conflicting memory access, focusing on removing unsafe and unstable code to ensure a smooth development process. Furthermore, Swift can compile errors to flag bad code, making it efficient to write and test.

There is no “nil” value in Swift objects; Swift generates a runtime crash whenever nil value is used, urging developers to fix the error immediately. However, for instances where “nil” is an appropriate value, Swift has an optional feature which allows developers to use nil using the appropriate Swift syntax.

Rapid App Development
Rapid App Development

Designed to operate at a fast pace with a concise syntax and using the LLVM compiler technology, Swift really does live up to its name, by enabling code execution to be 2.6x faster than Objective-C and up to 8.4x faster than Python 2.7. Swift also has a short error feedback loop because errors can be seen and fixed during the development process before compilation.

Rapid App Development
Compatibility with Objective-C
Compatibility with Objective-C

On Cocoa Touch, Objective-C and Swift can be used together, creating mixed-language apps. For developers, this becomes convenient especially when updating and modifying existing projects; they do not have to create an app from scratch, but can migrate an Objective-C codebase and then add to it with Swift’s syntax, saving a lot of time as compared to needing to completely rewrite it.

Supported by Multiple Devices

Swift is not just limited to compatibility with Apple devices. It is a cross-platform programming language which, in addition to compatibility with iPhone, iPad, Apple Watch, Apple TV and all Mac devices, can also create apps on Linux and Windows devices.

Swift in Comparison with Objective-C

Swift Development Company to Build your App

While Objective-C has been around for a long time when compared to Swift, developers are now preferring to use Swift for iOS development because of its code readability and clean syntax. Without updating the C language, Objective-C cannot be upgraded to a newer version. On the other hand, Swift does not depend on any language for any sort of upgrade which permits easier upgrades to the core language itself. Additionally, Objective-C has a two-file requirement to improve code efficiency while Swift eliminates this requirement by combining them into a single file. Swift compiles and carries out bug fixes during the compilation process which allows for a shorter testing process, a feature that Objective-C have.

With features like inline support for manipulating text strings and data, Swift in comparison with Objective-C has become a programming language less prone to errors and mistakes. Furthermore, to combine two strings, Objective-C has a proper combination structure making it time-consuming but with Swift, you just need to add the “+” sign to join two strings.

While Swift has its obvious advantages over Objective-C, it should be noted that most of the essential features of Swift are derived from Objective-C, including the power of the dynamic object model.
