The mobile industry is one of the fastest-growing sectors in modern society. The evolution of mobile technology has drastically changed our lives. Now, our mobile apps incorporate massive databases, AI, and cloud technologies, reflecting the advancement and growth in software development languages.


Google and Apple annually announce new technologies and products at Google I/O and Apple WWDC, respectively. After these events, developers get busier with the introduction of upgraded languages and frameworks, presenting new challenges. 

In this ever-changing mobile industry, Swift is noteworthy for its role as the primary language in the Apple ecosystem, enabling modern and efficient programming. Today, let’s explore Swift’s features and applications.



Who developed Swift Programming Language?

Who developed Swift Programming Language

Swift is a programming language developed by Apple. It’s used for developing applications across various platforms like iOS, macOS, and watchOS. Swift’s latest version as of November 2023 is Swift 5.9.1.



Why use Swift Programming Language?

One of Swift’s main features is its syntax. Unlike previous languages that used unnecessary semicolons or brackets, Swift omits these for improved readability. Its functions and methods are intuitively named for ease of understanding, making the code concise and easy to maintain. 

Swift also catches errors during compilation, reducing runtime errors, crashes, and bugs, thereby enhancing app stability and user experience.



Swift vs Objective-c

Swift vs Objective-c

Apple previously used Objective-C as the primary language for iOS and macOS. Swift includes modern programming features that are an improvement over Objective-C. 


Swift checks for type safety during compilation, making code execution faster than Objective-C. It also distinguishes between constants and variables for memory management, featuring robust memory management with Automatic Reference Counting (ARC). 

While many apps initially developed in Objective-C have transitioned to Swift, some projects still use both languages. However, Apple now focuses on Swift, with many libraries and frameworks being released exclusively for it.

According to Apple, Swift’s three main features are Safety, Speed, and Expressiveness. Swift’s concise syntax helps in identifying bugs during development, ensuring safer and faster app development. 

Its performance exceeds other languages like C and Objective-C when developing for various Apple OS. Swift is open-source, meaning developers continuously improve and expand the language.



What can you do with swift programming Language?

Swift Language and Support


Delegates, conforming to specific protocols, handle user-defined events, facilitate data communication between ViewControllers, and notify other objects when asynchronous tasks are completed. A common use case is implementing the UITableViewDelegate protocol for UITableView to define data sources and handle list item events.


Optional is a data type representing the possibility of a value being present or absent, enhancing safety by allowing checks for the existence of a value, thus preventing unexpected errors.


Extensions add new functionalities to existing classes, structures, and other types. They can add new variables, methods, or modify existing ones.

Closure, Async/Await: 

Closures are blocks of code that can be stored or passed like variables or constants. Async/Await simplifies asynchronous task handling, making code simpler compared to nested closure use.


Apple’s Combine framework is for handling values over time in a reactive programming style. It offers cleaner code for asynchronous tasks compared to traditional methods like Delegates and Closures.

UIKit, SwiftUI:

UIKit, the traditional framework for iOS UI development, is complemented by SwiftUI, which simplifies UI construction with a code-based approach and dynamic UI changes based on data state.



Swift for iOS/ macOS App Management

Each year, Apple releases new iPhones, MacBooks, and Watches, along with new OS and Swift language versions. 


This necessitates existing iOS and macOS applications to adapt to new versions. For instance, with the release of iOS17 and iPhone15, apps need to be updated promptly.


 Apple’s emphasis on security with features like “Sign In With Apple” in iOS13 exemplifies the need for regular updates. To offer the latest services, it’s crucial to have Swift experts for regular app updates.
