Why Choose Swift For iOS App Development? 9 Reasons to Know

iOS app development

As the demand for the iPhone grew, so did the technology to make it easier to use. Previously Objective-C was used, but developers found it difficult to adapt to the language. Swift has significantly altered the iOS app development industry. It is a very user-friendly programming language for Apple operating systems like iOS, macOS, and watchOS. The language has given entrepreneurs new opportunities to make previously impossible ideas work, and they can now build apps with Swift. Let’s look at what benefits Swift offers to its developers. 

Advantages of Swift for iOS app development 

Here are some benefits Swift offers to iOS developers for application development. 

1. Easy Coding 

It is a boon for the developers because coding Swift for iOS app development is more convenient than any language. If we talk about mobile app development, it is a demanding task with complex coding lines. Swift is concise and can reduce the number of lines of code used, making programming faster and more efficient.

Swift coding becomes smoother as the method and function calls use a comma-separated list of parameters within the brackets. Code reusability is also high, allowing developers to save time. And remember which part of a specific code is to reuse without requiring changes to another. 

2. Simple maintenance 

One of the primary reasons developers prefer Swift for iOS app development is its ease of maintenance. Unlike Objective-C, which heavily relies on C. Swift has no such dependencies, making it relatively simple to maintain.

To improve build time and code efficiency, iOS developers must keep two code files (Objective-C header (.h) and implementation files (.m)) in the case of C and Objective-C. Swift combines these two files into a single code file (.swift). It gives developers more time to plan the app logic and improve code quality. 

3. Open-source 

Apple declared Swift as an open-source language, which increased its popularity among developers. With this announcement, the language became free to use, allowing small and large-scale businesses to save money on development. Because open-source languages are customizable, developers can tailor the code to their specific needs.

It is also simpler to track bugs and upgrade codes. Additionally, businesses can obtain highly customized mobile applications based on business requirements. Apple receives continuous feedback from the community and makes changes to improve the platform. You can hire a Swift app development company in Gurgaon to help you discuss your requirements. 

4. Error handling 

Rather than the usual combination of “try-throw-finally-catch” for handling exceptions, the language takes a fundamentally new approach to error handling. Enumeration is used here to process the Success and Failure outcomes. This algorithmization method allows tracking all potential errors, lowering the likelihood of incorrect application operations after the release.

5. Speed 

As the name speaks for itself, Swift has this superpower that drives iOS developers to choose Swift over Objective-C. Swift provides high speed, whether during development or testing, which ultimately helps to reduce app development costs. It has one of the quickest algorithm calculation metrics.

It also outperforms Objective-C in terms of speed because it uses a single code file rather than two. Swift allows iPhone app developers to use generics and higher-order functions, making their code more readable and reusable. You can hire iOS app developer to help with your Swift project. 

6. Increased stability 

The developer’s focus is on security and stability. Swift is an excellent choice for any iPhone mobile app development company looking to build a secure and stable iOS mobile app for its customers.

As previously stated, Swift employs clear and simple syntax, which the likelihood of developers making mistakes while writing codes that are frequently overlooked in Objective-C, thereby adding a layer of quality control. Even if an error occurs, it is far less frequent than in Objective-C, thanks to Swift’s improved typing system and error handling capabilities.  

7. Dynamic library support 

Unlike Objective-C, Swift supports dynamic libraries. Dynamic libraries are executable pieces of code that link to the app at runtime or load time. The feature connects apps created with older versions with those with the most recent releases. Simply put, it allows apps built on a specific version to update to future releases.

Dynamic libraries are loaded directly into memory, which reduces the initial app size and improves application performance. With this library support, iOS app development companies can create professional projects. 

8. Engaging coding 

Interactive coding is another advantage of Swift for iOS app development. Swift Playground allows hiring iOS app developers to run real-time tests on new algorithms without building the entire app. It is commonly referred to as a Read-Eval-Print-Loop, or REPL, and is extremely useful for learning, experimenting, and rapid prototyping.  

Apple has added inline code execution to help developers create a slew of codes or algorithms while receiving feedback. The feedback improves the speed with which code is written with the help of data visualizations. Swift and Playground work together to make app development more accessible and more approachable. 

9. Playgrounds systems  

Playground enables programmers to test new algorithms without building an entire app. iOS now supports inline code execution, allowing coders to create large amounts of code or algorithms while receiving feedback.

The data visualizations can improve the speed with which code generates. Playgrounds and Swift reflect Apple’s efforts to make the development process easier and more accessible for any mobile app development company


Swift has quickly established itself as one of the leading programming languages for developing engaging, intuitive, and user-friendly iOS mobile apps. As above discussed are some of the key reasons for choosing Swift for iOS app development. For more consideration, consult an iOS mobile app development company for more Swift projects. 


1. What is the purpose of Swift language? 

Swift is a general-purpose programming language with a modern approach to safety, performance, and software design patterns in mind. 

2. What exactly is Swift-type safety? 

Swift is a type-safe language that helps you understand what types of values your code can work with. 

3. Is Swift a front-end or a back-end language? 

Swift is used to creating software that runs on both the client and the server.
