So without wasting further time, let’s start with today’s blog..

Swift vs Objective C: Meaning

What Is Swift?

In 2010, Chris Lattner, an Apple employee, developed this new programming language named Swift which was available to general public in 2014.

Swift quickly become popular due to its simple design and smooth functioning. With its current features, automated memory management, and simpler syntax, many developers now prefer it over Objective C for iOS app development.

This general-purpose programming language offers a productive method for developing server, desktop, and mobile software, particularly suitable for coding that prioritizes performance and facilitates rapid bug finding and resolution.

Swift is especially easy for those who are familiar with contemporary programming languages like Python or JavaScript. In recent years, both Swift and Objective C have gained increasing popularity. Swift, with its novel features such as optional and type inference, enables the creation of shorter, cleaner code with fewer errors and crashes compared to Objective C.

All in all, Swift is a promising programming language that works well with Linux and is expanding rapidly.

What Is Objective C?

The Stepstone firm developed the well-known programming language Objective C in the early 1980s. Because it is an object-oriented programming language, developers may easily handle complicated jobs and structures. However, new people may find Objective C difficult due to its sometimes complex syntax.

Although Objective C is an old programming language, it is still useful today. Despite lacking some of the more recent capabilities than Swift, Objective C has a strong and vibrant community.

The manual memory management of Objective C programs is a major obstacle. Although it might be laborious and time-consuming, proper memory management is necessary to maintain the functionality of apps. The Objective C and Swift comparison will clarify how swift addresses this issue and enhances memory management in comparison to Objective C.

Swift Vs Objective C: Features

Swift is newer in comparison to Objective C and thus has more unique features like type inference type safety, polymorphism, and dynamic libraries for better performance of iOS App Development. Some of the basic features of Swift and Objective C are discussed below :

Features Of Swift

  1. Memory management system that operates automatically: A programmer can save time and effort by not having to worry about how much memory a project will require thanks to Swift’s Automatic Reference Counting (ARC) functionality, which manages memory automatically.
  2. Learning Swift is simple: Thanks to its many features, even non-programmers may learn Swift easily and quickly. Moreover, Swift offers a sandbox where new users may quickly and freely pick up the basics of the language.
  3. Concise syntax for codes: Because of its concise code syntax, Swift allows developers to accomplish a lot with fewer lines of code. It minimizes the amount of scripts needed for string manipulation and repeating statements.
  4. Swift moves quickly: Because of Swift’s efficient compiler, you can write code more quickly and easily without having to worry about accounting.
  5. Safe language for programming: Error probability is decreased by using the Swift programming language. Swift also gets rid of bug inclinations by causing a runtime crash that forces programmers to address the problem right away.

Features of Objective C

  1. Data concealing: One safety aspect of the Objective C programming language is data masking, which greatly reduces the risk of unauthorized access to data. Data access is controlled and intentional or unintentional program modifications are thwarted with the help of the data-hiding safety feature.
  2. Compilation: Programmers find it simpler to prevent other users from having direct access to the state values of each object variable when they utilize Objective C’s encapsulation feature. This Objective C feature also makes it simple to set variables flexibly to be read-only or write-only, hide data, and adjust to changing requirements.
  3. Inheritance: If you utilize Objective C, you might want to add new classes to your existing ones. You can accomplish it with the aid of the Objective C programming language’s inheritance mechanism. In addition to allowing you to create classes, inheritance allows you to design a modification while maintaining the same features, reuse code, and independently extend the original program using accessible classes and interfaces.
  4. Quick program: Every software developer wants to be able to code without having to wait around for the programming language or tools to be used. You can have this wish fulfilled thanks to Objective C’s fast program feature, which makes programming more effective and rapid thanks to the language’s design.
  5. Polymorphism: The Objective C programming language’s polymorphism feature allows users to access several objects via a single interface. There are two varieties of the polymorphism feature: static and dynamic.

Comparison Table Of Swift Vs Objective C

Swift Vs Objective C: Performance

difference between Swift and Objective C

Swift performs at a faster pace than Objective C . Because of its extremely effective structures and tools, Swift is 2.6 times faster than Objective C . While still quite quick, Objective C is significantly slower than Swift.

Swift Vs Objective C: Speed Of Coding

Swift allows for speedier coding than Objective C . Objective C is difficult to write code in due to its complex grammatical structure, which causes developers to create code in Objective C more slowly. Swift is a fairly quick programming language to write and understand because it has fewer imports and stringent code-writing guidelines.

Pros & Cons Of Swift Vs Objective C

Swift Benefits Unleashed

  1. Swift is a safer programming language, which is one of Apple’s advantages. Apps created in Swift are less likely to crash and have errors than apps created in Objective C due to its capabilities (such as generics, optionals, and type inference).
  2. Apple is concentrating on developing Swift, Apple actively supports the developers who use this language and is always improving it with new features. There are technical sessions regarding Swift at every WWDC (Apple’s annual Worldwide Developers Conference), and the programming language has a vibrant developer community. Swift can even be used as a backend language by developers thanks to certain frameworks.
  3. The Swift UI framework is included for creating interfaces. In 2019, Apple unveiled SwiftUI, a framework that makes it easier and faster for developers to create engaging user interfaces than UIKit (the sole UI framework available for Objective C ). Although it still has a ways to go before it becomes the primary tool for creating UI in iOS, it has a lot going for it and can be used in place of UIKit. SwiftUI is a match made in heaven if you require a simple sample app to test how your idea might look.
  4. Developers simply like to use Swift, In contrast to almost 76% of iOS developers who detest Objective C , 63% of them adore utilizing Swift, according to the 2022 Stack Overflow Developer Survey. It goes without saying that a motivated developer performs better than one packed with fear!

Disadvantages Of Swift

  1. It’s only recently launched: Even though Swift is reliable and secure, regular upgrades may bring in features that are incompatible with previous iterations of iOS. That may motivate you to update your apps to a more recent iOS version, but it might also compel you to discontinue support for older devices (often those that are more than six years old).
  2. The cross-platform functionality is lacking: Although Swift is compatible with Linux, Windows, and all Apple platforms (as of 2020), React Native, Xamarin, and Flutter are the best choices for cross-platform applications. While Kotlin Multiplatform Mobile is still in its infancy, there is promise for using Swift with it.

Advantages Of Objective C

  1. It is tried and true, having been around for more than thirty years. Yes, millions of lines of code and numerous third-party frameworks with extensive documentation are written in Objective C.
  2. Furthermore, there is a response available for almost all queries concerning Objective C : Among the more than 321,899 Swift queries on Stack Overflow, 292,632 have the Objective C  tag applied to them.
  3. Good C and C++ compatibility,  Objective C  interfaces rather well with C and C++ programs since it is a superset of C.
  4. The language used in Objective C  is stable. It is unlikely that developing an Objective C  application will require you to invest in paying for the app’s migration to a new language version after a few months.

Disadvantages Of Objective C

  1. Its advanced age may also work against it :  Many of Objective C ‘s libraries and tools are no longer developed as Swift has mostly replaced them.
  2. Objective C  is more difficult : Compared to contemporary programming languages, it is very different. For instance, compared to Swift, concepts like memory management are more difficult to understand. As a result, learning Swift is made simpler for novices and Objective C  developers than the reverse.
  3. There are fewer and fewer developers who are proficient with it : Since Objective C  is more difficult to learn and utilize, most aspiring iOS developers begin their careers by learning only Swift. Conversely, seasoned engineers who are conversant with Objective C  are typically conversant with Swift, or at the very least prepared to pick it up.
  4. Hacking an Objective C  app might be simpler than hacking a Swift one : Since Objective C  is widely used and has been around for a while, reverse engineering tools have also advanced significantly.

Swift Vs Objective C- Adoption & Popularity Trends

Since its 2014 release, Swift has gained popularity due to developer preference and Apple’s active support. Currently, it ranks 9th among programming languages, with Objective C at number 10, used by 2.39% of developers.

The pattern is expected to continue, with Swift projected to surpass Objective C in popularity and become the preferred language for iOS app development by 2023. Swift’s status as the top choice is reinforced by the anticipated growth of the mobile market to $165 billion.

Swift’s increased appeal is also due to its contemporary features, easy-to-understand syntax, and robust Apple support. It’s possible that even more developers may use Swift for their app development projects as it continues to grow and change.


In conclusion, we can say that Swift might be a better option in terms of advanced features like type inference, dynamic speed, type safety features that ultimately help developers in making advanced iOS solutions altogether. Objective C is also good but with Swift supporting backward compatibility, it ultimately gets more market attention and developer’s interest.

Therefore, Swift is most likely a better option if you are beginning a new project from scratch. It could be simpler to continue using Objective C if you are working on an existing project that was created in that language. The decision between Objective C and Swift will ultimately come down to your own demands and specifications.
