Which One To Choose For iOS Development: Swift Programming Or Objective-C?

Published on 14 February 17

There is always a strong debate over whether to use Swift or Objective-C language for iOS application development. Selecting a right programming framework depends on the application requirements, team context and preference, and fidelity to a particular language. Hence, instead of debating on Swift and Objective-C, the development team should consider different aspects of a project such as a project scale, its scope, technical considerations, team composition.

In 2014, Apple released the Swift programming language and since then Swift app development companies started emerging in the market rapidly. Apple has released different versions of Swift in order to keep the consistency in iOS app development.

According to the experienced app developers, Swift has provided amazing implications and created eagerness in new app developers about iOS app development. Generally, Swift and Objective-C both are the best options for building iPhone applications. But both languages have its own features and benefits that cause different preferences about these two among the developers.

Advantages Of Learning Swift :-

The fundamental concepts of Swift programming language are easier to understand. Following are some reasons that will explain why one should learn Swift programming:

Safe :-

Swift is safe language along with modern and powerful features. The modern features might be a not astonishing thing for the new developers but the safety of the language does.

In Objective-C, no activity happen when developers call null pointer variable. The line of code with null-pointer might look beneficial and crash-free but there are also chances of generating a lot of bugs. Because with null pointer variables line of code become a no-op (no operation). And such a no-op variables cause unpredictable behavior of a mobile application.

The optional types in Swift programming generate the compiler errors when developers write a null-pointer variable in code. This generates a short feedback loop and warns developers to avoid the use of no-op variables in the code. Sometimes, swift also provokes run-time crash if a null-pointer variable is used. This will help developers to fix the errors in code as early as possible.

Easier To Read :-

Most of the program writing conventions are eliminated by the Swift language. For example, use of semicolons to end the line, parenthesis to surround if-else statements etc. Because Swift is not built on C, so keywords of Swift can be easily unified. Swift has dropped a number of keywords and symbol that are related to object-oriented programming concepts.

The code written with Swift closely resembles natural English. The programmers from Java, JavaScript, C/C++, Python can easily adopt Swift as their tool because of its readability.

Easy To Maintain :-

In Objective-C developers require handling two code files in order to improve the efficiency and build time of an executable application. Swift programs files are easier to maintain. Swift programs do not need to handle two file requirement.

The Xcode and LLVM compiler of Swift automatically determine the dependencies and perform the incremental build in the program. Swift merges the Objective-C header (.h) file and implementation (.m) file into single code file (.swift)

Why Learn Objective-C?

It is fair enough to say that Objective-C is the origin of iOS application development. It is the dominating programming language for iOS development for a decade. For the Mac OS app development, Objective-C is the top choice since 1980.

The iOS Software Development Kit (SDK) has fundamental concepts of Objective-C. Even though developers write code in Swift, but they are virtually interacting with components that are basically driven from Objective-C. The provision of third party framework and libraries are key features of Objective-C.

Moreover, major knowledge mediums like e-books, blog posts, conference videos etc. are possible only because of Objective-C. The Objective-C code is the main reason behind the execution of Internet protocols for the mobile applications. Many tools used for iOS development are not optimized with Swift. But those tools are better compatible with Objective-C. Objective-C offers the most robust language runtime environment. Hence, for most of the app development companies, Objective-C is still a favorite choice.

Every iOS application development uses the main foundation of APIs. Basically, Objective-C offers a strong set of APIs with some wonderful features. Swift delivers seamless data wrapping and memory management functionality. But, there are C-based functions and APIs that are used for memory management and data wrapping.

Final Thoughts :-

Both Objective-C and Swift app development companies see the bright future of iOS platform. The main vision of both languages is to extend the success of iOS applications. Apple has released these two languages to boost the app development process to deliver various technological benefits.
