Benefits of Using Swift


#1

1- Swift is faster

The performance of Swift is almost the same as that of C++, which is considered the fastest in algorithm calculation arithmetics. Apple had this idea in mind and worked to improve the speed of Swift. For example, Swift 2.0 has beaten C++ in several computation algorithms, such as Mandelbrot algorithm. Objective-C is slower because it contains C API legacy.

Swift is faster than Objective-C, because it removed the limitations of C language and has been improved with the help of advanced technologies that were unavailable when C was developed. As mentioned by Apple, Swift was originally designed to operate faster.

Despite the fact that languages are different, they both integrate, and work with Cocoa and Cocoa Touch APIs, for all Apple platforms. Therefore, a regular app-user would not recognize the difference in operating speed between Objective-C vs Swift. Speed also depends on a programmer’s level and capabilities, since a slow app can be written in Swift as well.

2- Swift is safer

Nowadays, an app’s data security is a substantial characteristic of a successful product. The construction of Swift has been designed to exclude and avoid mistakes with the help of its features – generics, optionals, and type interference to achieve app stability. Therefore, apps developed in Swift are less prone to bugs and crashes.

3- Swift is more readable

To start, code in Swift more closely resembles English, making it easier to read and requiring less time to check the code. As well, in general, it requires far fewer lines of code for the same feature. Swift is easy to read by JavaScript, Java, Python, C#, and C++ programmers who are able to use it to some extent.

4- Swift has less code

Swift is a more compact language for programming. However, this fact doesn’t imply code simplicity, of course. At times, it can be very difficult to write, but it brings more benefits and is highly reusable. The latter point cannot be applied to Objective-C.

5- Swift is less error-prone

Swift’s syntax and language constructions exclude the several types of mistakes potentially possible in Objective-C. This control means fewer crashes and cases of unexpected behavior. This, however, does not prevent bad code from being written, of course, but a developer is better protected from making unwanted mistakes. This can be called “ quality control,” in a way.

6- Swift integrates with memory management

What about Objective-C vs Swift memory management? ARC (Automatic Reference Counting), the memory management functionality inside the Clang compiler, manages the memory of digital objects. This is easily handled with Swift working across procedural and object-oriented code using Cocoa API. With regard to Objective-C, procedural code works with Corel Graphic API and it is the developer’s responsibility to control it.

Hence, in Swift coding, unified memory management developers should not give attention to each digital object, but rather concentrate on the general logic of the application and its features.

7- Swift is an open-source language

Swift was originally created for Apple platforms (iOS, OS X, watchOS, tvOS) and was further expanded to Linux. Its creators understood the fact that to build a remarkable modern programing language, it should be available for everyone. Swift helped to develop many third-party frameworks & tools and has resulted in a growing community.

As well, Swift code is more portable to other platforms than Objective-C could ever be.

8- Swift has interactive coding

Swift Playgrounds makes it possible to test code on the spot without compiling big pieces of it or creating the whole app. Playgrounds visualize data and programmers can quickly check and correct everything along with further development.

9- Swift is closer to other platforms

Swift is easier to understand for non-iOS developers. It can be used as a script language.

10- Swift is Apple’s ongoing focus

Apple Inc. is concentrating on evolving Swift as its core programming language.
