Why Is Swift So Popular in Developing iOS Apps in 2022?

Share on:

The most popular programming language used for iOS, macOS, iPadOS, watchOS, Linux, tvOS, and z/OS is Swift, which Apple debuted in 2014. The open-source LLVM compiler framework created this robust and user-friendly programming language. It uses the Objective-C runtime library, which enables Swift, C, Objective-C, and C++ code to execute seamlessly in a single program.

Objective-C was the primary language used for OS X and iOS app development for a considerable time. Object-oriented capabilities and a dynamic runtime are added to Objective-C, a superset of C, but Swift is steadily gaining ground in the market for iOS app development.

Swift’s concise yet compelling grammar creates an enjoyable and interactive coding experience. Swift offers some contemporary characteristics that developers adore enhancing. The written code is entirely secure and aids in creating lightning-fast running software. Swift employs a blend of C and Objective-C, avoiding direct built-in C compatibility and the associated restrictions. This language merely redefines our idea of app development across all iOS platforms with the aid of Cocoa and Cocoa Touch.

So, why is Swift still famous for creating iOS apps? We also have no doubts that Swift is superior to its rivals, as are many other developers. Swift offers a variety of advantages, as given below.

Using Swift for iOS App Development Has Many Advantages


Let’s begin with how these points would benefit in developing an iOS app:

1. Easy to Read and Write

Without a doubt, Swift is generally simpler to read and write than most languages due to its highly plain syntax. Software created with Swift typically runs smoothly and rapidly since the code written in it is typically shorter than that reported for Objective-C. This is because Swift omits the semicolon at line ends and braces around conditional expressions in if/else statements. Additionally, Swift uses a comma-separated list of arguments for method and function calls, which undoubtedly makes coding in Swift much more transparent.

In general, Swift-written codes resemble plain English texts more, which allows developers to save time by not having to spend as much time interpreting and searching for the troublesome code.

2. Simple to Keep Up

This is the key reason why Most developers prefer swift-based iOS app development. Unlike Objective-C, Swift is not heavily dependent on C, which is why developers adore it. This makes Swift relatively simple to maintain. Ios developer hire

Developers using C or Objective-C must have two code files to improve build time and coding productivity. Swift does not operate in the same way. Swift is simple to handle and manage since it combines these two files into a single.swift code file. This allows iOS developers using Swift more time to prepare the app logic and improve the quality of their code, resulting in an app that runs more smoothly.

3. Reliability and Security

Every business owner wants to have a secure app. Any mobile app development company hoping to produce a fast and reliable app for its customers should consider developing an app with Swift.

Swift is regarded as a more stable language for developing mobile apps because it has comparably fewer crashes and instances of undesirable behavior. It lessens the possibility that programmers may make mistakes when writing the code, offering another level of quality control for your app. Swift is a safe, secure, and stable language to work with such reasons.

4. Backs up Dynamic Libraries

Swift offers support for dynamic libraries, making them simple to use. An archive of object files called a dynamic library can be connected to an application during runtime and load time. Apps presently developed on a specific version can easily be updated to Swift’s future releases thanks to this functionality. These libraries are instantly downloaded into the memory, which reduces the initial app size and ultimately improves speed.

5. Free Software


Apple declared Swift an open-source language in 2015, increasing its popularity among developers. Swift is free to use because it is an open-source language, and you are not required to pay anything. Due to the cost savings associated with avoiding the development of an iOS app, this serves as an added benefit for both small and large organizations.

Since open-source languages are simple to modify, Swift developers can change the code to suit their needs. You can get highly customized apps created for your business needs as an entrepreneur.

6. Needs Less Programming

It has already been mentioned that Swift requires less coding because of its simple syntax and avoidance of dated conventions like semicolons and brackets. Additionally, this language is less error-prone due to its inline support for manipulating text data and strings.

Developers find it much easier to manage classes in Swift because they do not need to separate the interface and implementation into two pieces. This finally cuts the number of files in half. However, with Swift, you can quickly join two strings using the “+” sign, which minimizes the code and, of course, the effort of the developers. When working with Objective-C, developers must combine two strings, which results in lengthy code.

7. Swiftness

This is one of the main reasons Swift is so well-liked by iOS developers. It has several speed advantages, whether during the development or testing phases, which lowers the cost of developing an app. In terms of speed, a program created in Swift will be approximately 3.9 times faster than a Python implementation of the same method. Additionally, Swift is quicker than Objective-C since Swift only utilizes one code file, whereas Objective-C needs two.

Since C++ is regarded as one of the fastest development languages, many programmers compare Swift’s performance to that of C++. Apple made it very clear when it released Swift to the market that its main goal was to increase performance and run the app logic much more quickly.

8. Collaborative Coding

Collaborative Coding

Developers can test a new algorithm in real time using Swift Playground. The Read-Eval-Print-Loop (REPL) platform type is beneficial for learning, experimenting, and quick prototyping. By using data visualizations to speed up code writing, Apple has provided this feature, making app development more approachable and attainable.


Most business owners who want to have an iOS app created for them frequently struggle with the decision of whether to choose Swift or Objective-C for their app development. The best language to use largely depends on the kind of app that person wants. Although Swift borrows a lot from Objective-C, it also adds brand-new features that help programmers write more secure and dependable programs.

Swift’s grammar is more straightforward, making it simple to comprehend and less error-prone. The language’s most recent changes undoubtedly bring many benefits and present new options for developers to investigate. It enables them to produce more approachable, attractive, and user-friendly apps to effectively expand your organization.
