Top 5 Reasons For Shifting To Swift From Objective-C For iOS Application Development In 2020

Key takeaways:

  • Two major differences between Swift and Objective-C.
  • Features of Swift over Objective-C.

For iOS app development, most of the developers prefer Swift and Objective-C. If we talk about the past, Objective-C got more preference over Swift. And there are various reasons for this. 

But for now, it’s the right time for the developers to switch to Swift from Objective-C for extra benefits. This blog is all about those benefits. 

If anyone among you doesn’t know what Objective-C is, here it is. It is basically a superset of the C programming language. The only add-on in Objective-C is object-oriented features and an active runtime environment. 

Swift is also called “Objective-C without C”. So, why should businesses shift from Objective-C to Swift? What benefits does Swift offer? Is it worth learning Swift? How is it different from Objective-C? 

If you have these kinds of questions, then get answers to this in this blog. So, let’s start with two major differences between the two.

Two major differences between Swift and Objective-C

The following are the two major differences between the two iOS app development languages.

  1. Objective-C is a superset of C. Hence, it follows the templates of C. However, Swift isn’t a superset of C. So, it doesn’t obey the C’s system constructs. This allows the implementation of custom operations in Swift for additional functionality.
  2.  Likewise C, Objective-C is statistically typed. On the other hand, Swift is dynamically typed. So, it can make the most of the latest types of systems. Moreover, dynamically typed languages get your work done faster.

So, these reasons prove why Swift is a healthier option than the Objective-C considering Swift’s future. 

Eye-Catchy statistics regarding Swift

iOS app development

Before 2016, Swift was the 11th most loved programming language. But since 2016, it has occupied an outstanding 2nd position, leaving behind languages like Python, Node.js, etc. 

This is the reason why companies like LinkedIn, Lyft, and Hipmunk have already upgraded their iOS apps using Swift.

VSCO Cam, a popular photography camera app for iOS developed its latest version in Swift itself. 

So, now you must know what to do next, being an iOS app developer.

Five reasons that make switching to Swift a promising idea 

1. Better code readability

This is the reason that makes developers admire Swift, even if they have been working with Objective-C for long. 

Swift promises a crystal-clear syntax with higher readability. This makes modifications in the code easier. Moreover, in Swift, the same code of Objective-C runs in a lesser number of lines and time. 

In this way, it reduces the overall app development time and cost. This is what every company would welcome with both hands.

2. Swift is quick

Swift’s performance is similar to that of C++. Hence, it matches the speed and effectiveness of C++. 

Also, Apple made it clear that in the coming future, they are going to make Swift faster than ever. Doing this will make Swift use less time to run the app’s logic. 

3. Fewer lines of code

In coding, more lines mean more time consumption while reducing errors. This goes with Objective-C where developers are made to use numerous lines for a basic iOS app. But with Swift, the same app consumes fewer lines of code. 

This also makes the code less error-prone. In return, this saves the overall app development time. So, with Swift, there’s an advantage of getting the work done in fewer lines of code. 

4. Swift is safer than Objective-C

For any start-up/enterprise, developing a 100% secure app is number one in its priority list. This is difficult to achieve with Objective-C. So, here again, Swift overpowers Objective-C. 

This is because Swift’s syntax and architecture remove the mistakes possible with Objective-C. Therefore, switching to Swift excludes the security risks generally related to Objective-C.

5. Low maintenance

A developer’s job doesn’t end with the development and deployment of an app. The main job starts after this. This is the job of maintaining the app for enhancing the user experience. 

It is important for a developer to keep an eye over the app in order to integrate changes in it. This, in turn, satisfies the user needs from that application. But various start-ups and enterprises believe that the app’s maintenance is difficult in Objective-C. 

This is because any developer working on an app developed using Objective-C must possess the knowledge of C. And today, it’s difficult. 

But, with Swift, there is no such need. This makes the maintenance job of an iOS app using Swift much more relaxing and flexible.


Hence, these are the key differences and comparisons between iOS’s two prominent languages, Objective-C and Swift. Now, you must understand that it’s the right time for businesses to start building iOS apps using Swift. 

So, if you’re thinking of pursuing an iOS app developer career, start your career with Swift only.
