Swift has been steadily approaching towards top preferences of the iOS developers. Initially, Swift was launched and acquainted with the iOS community as a new contrasting option for application coding due to the dominance of Objective-C. The iPhone application development was started with Objective-C and it is obvious to have conflict when things come to whether to choose Swift or Objective-C. But application developers has accepted Swift over the other solutions available for iOS development.

Today many developers are hoping to switch over towards Swift while some are still uncertain of why Swift is a right choice for them. For existing application developers, Swift has brought back a new interest in iPhone app development company. While on the other hand, it has created a little bit of complexity for the beginners. As the matter of fact, Swift generally derives many concepts of Objective-C programming. Hence, developers who have already worked with Objective-C, Swift might be easier for them to learn.

Following are the convincing reasons which will help to understand why Swift is the right choice for iOS application development.

Easy Coding

Application coding can never be considered as a simple task. It is the important phase in application development cycle. Swift has eliminated many Objective-C concepts in order make programming easy and efficient. For example, the null-pointer concept is eliminated by Swift. The use of null-pointer creates no-op (no operation) block in code which is responsible to create bugs in the application.

Application developers can use Unicode characters to name variables and constants in the source code. But, the variable name should not contain a line or box-like characters, mathematical symbols, arrows, and private characters. Developers can also include numbers (except in the beginning) in a variable name.

To make source code more expressive, Swift uses multi-line comments. It will help explain the functionality of the specific code in more proper manner. Also, the reader (other developers in a team) can quickly navigate through the application code. Developers can use nested structure of multi-line comments to cover larger size code.

In other programming languages, semicolons are used to indicate the end of code statement. Swift has eliminated this convention and developers do not need to follow each code statement with a semicolon.

Highly Interactive Environment

Xcode Playgrounds and Swift Playgrounds are two effective frameworks that Apple has released along with Swift programming.

Beginners can learn how to code iOS application using Xcode Playgrounds. Actually, it is the based on Mac application called “XCode.” This application allows beginners to explore and learn different Swift concepts. Developers can create prototype of applications using XCode playground to enhance their iOS app development skills.

Swift Playgrounds is an iPad application, provides developers same interactive platform as Xcode Playgrounds. Swift offers interactive engagement with users as it provides instant feedback and makes application development easy.

Fast And Steady

Application runtime of Swift is robust than Objective-C. Swift applications use a concept of objects and type to improve the application performance. The strong error handling and typing feature make Swift applications more steady. Swift has Involuntary reference counting system which helps to avoid the potential errors in source code.

Dynamic Application Development Environment

Many enterprise-based applications load slowly in smartphones. But, Swift applications use dynamic libraries as these libraries directly loaded into memory by cutting down initial app size. This activity ultimately improves the application performance. Swift is a multi-faceted programming language that allows development of all types of iOS applications. iOS developers can developed commonly used enterprise application to advanced Apple Watch app.

Swift Package Managers

The application developed with Swift are compatible with watchOS, tvOS, Mac OS, and Linux. Most of the times, it is necessary to categorize the applications respective of their platforms. Swift package managers and bundle directors help to track application activities on different platforms.


Applications developed with Swift are compatible with the latest and previous iOS versions. Because the Swift applications have Xcode Swift runtime dynamic libraries fixed within the application bundle. These libraries allow consistent and seamless performance on different versions of Swift as well as iOS. iPhone app development company can now deploy the Swift app in AppStore including dynamic libraries. A digitally signed certificate confirms the integrity of application and dynamic libraries.


The above-mentioned reasons surely help to motivate iOS developers to choose Swift as their application development language. The Apple has launched Swift language to extend the success of iOS application development. This platform has provided numerous new methods to bring effectiveness in iOS applications. Thus, Swift might be the best replacement for Objective-C in the future.
