Key Features of Swift Programming Language

Swift is a powerful programming language developed by Apple for macOS, iOS, watchOS, tvOS, and Linux. It is initially built for iOS and OS X apps but now it is an open-source language. Swift is developed intended as a replacement for C, C++, and Objective-C since it is somewhat same in performance from these languages. Swift is an alternative to objective-C that used all modern programming concepts and provides simple syntax much familiar with users compared to difficult objective-C. It is familiar to developers using objective-C. 

Swift is developed for maintaining and writing correct programs in a secure and easy way for the developer. The key features are:

Open-source- Swift is developed at swift.org, an open-source framework with source code, bug tracker, mailing list, and regular development list. It is handled by a team of developers, they work with the community. Swift has support for all Apple platforms, it makes programming easier, faster, and safer.

Safety- Swift is the way to write a program in a safe manner. It is very important to check the code before it goes for production, swift check the code and remove the entire unsafe code. Other feature is a swift object can never be nil; it will generate an error as soon as you write the bad code. Thus it saves them time and gives bug-free codes. 

Fast- From the name itself, it shows this feature. Swift is built as a replacement for C-based language thus the performance is the same in many tasks. It automatically corrects the errors and tests the code thus it performs faster.

Simple syntax- Swift provides simple and easy to use syntax which exactly developers expect. Swift’s syntax features allow you to write more expressive code. Swift has used objective-C features like null ability and generic which makes the swift code safer and cleaner. Programming is easy since it reduces the code needed.

Multiplatform support- Swift is built with multi-platform source compatibility with platforms like iOS, MacOS, tvOS, watchOS, linux, etc. you can create software compatible with all the operating systems. It can be ported across any platform and any device. You also can create your own operating system.

Objective C compatibility- Swift is fully compatible with objective c thus we can write program in any language. We can develop app with mix-language. It has a tool through which you can shift from objective-C to swift.

 Swift makes the code easy to read and write, much faster, cleaner and safer program. It also borrows some features from other languages written in clean syntax that makes code easy to maintain and read.
