Why Future Favours Apple’s Swift?

Jigar Panchal

Swift was introduced at Apple’s 2014 Worldwide Developers Conference (WWDC).  Swift is Apple’s modern programming language that lets developers build OS X and iOS apps. It seems likely it will eventually replace Objective-C and already creates more stable code in shorter development cycles than the language it is destined to replace.

Why Swift?

In an initial stage, Swift was described simply as ‘Objective-C without the C’. Objective-C was innovative and powerful and easy to use language in the early 1990’s, but many languages today provide more productive application development environment. While Objective-C is a strict superset of C, it’s a really hard for developers from other platforms and languages to quickly pick up Objective-C.

In addition, Apple wanted a language compatible with the existing Objective-C frameworks on both OS X and iOS while taking a number of innovative features of the languages created during the period of 20 years. As computer become more powerful, languages and compilers simply increase work for the developers.

How Swift helps the IT Industry?

Swift made up by many time saving features like displaying outputs in real time and instant feedback on errors. This saves developers from having to create massive amounts of code before seeing the results. Developers can also say goodbye to sifting through code line-by-line to find tiny errors in code when an issue arises. These benefits will prove cost-effective for corporations and IT industry’s top innovators for developing for Apple.

Why Swift is preferred programming language for iOS?

Increased readability of code

Swift syntax and keywords are simpler as compared to Objective-C. Developers have no required to put semicolons at the end of statements. Moreover, Swift requires to use dot operator to access methods. Developers, who are well-versed in Python and JavaScript, can easily switch to Swift.

Files are easy to maintain

In Objective-C. Developers are using two file systems: ‘filename.h’ as header and ‘filename.m’ as implementation files, while Swift combines both into ‘filename.swift’ file. Additionally, Swift developers do less bookkeeping and can send more time to create application logic. Swift eliminates boilerplate work and improves the quality of code and features that are supported.

Easy to manage app memory

Swift uses Automatic Reference Counting (ARC) to track and manage app’s memory usage. Objective-C supports ARC within cocoa APIs and object-oriented code paths. It is not available for procedural C code and core graphic API’s. In Objective-C, it is the developer’s responsibility to handle memory while working with Core Graphics API. In Swift, memory leaks are impossible to an extent.

Less coding

In Swift, string interpolation is bit easy as compared to Objective-C, because it usages operators such as ‘+’. In Objective-C, developers require to remember special string tokens (%s, %d, %@) and provide a comma-separated list of variables to replace each token. Swift supports string interpolation, so there is no need to memorize tokens and allows programmers to insert variables directly inline to a user-facing string, such as a label or button title.

Lesser name collisions

With Objective-C, developers are facing the problem regarding to manage the namespaces. There is no formal support for namespaces. Swift provides implicit namespaces that permit the same code file to exist across multiple projects without causing a build failure.

It’s clear that Swift will have a huge impact on client-side app development in the IT industry. Swift is a new way of designing, building, and running applications. It is considered to be a faster and more effective of building applications on iPhone, iPad, and MAC. Swift is known as the de-facto programming language, because it is supporting the development for complex applications and improving the future of embedded systems like Apple watch.
