Why Swift is Brilliant for iOS Development: Top 8 Benefits

With more businesses recognising the advantages of iOS app development, iOS applications now account for approximately 28.36% of the global operating system market share. iOS apps are widely known for delivering reliable performance, high security, exceptional user experience, and robust functionality—all thanks to Apple’s strict quality guidelines.

When companies plan their mobile applications, especially for the iOS platform, choosing the right programming language, SDK, and tools is essential to ensure success.

Two key programming languages often used for iOS development are Swift and Objective-C. While Objective-C has been around longer, Swift—despite being relatively newer—has become the preferred choice for modern iOS app development due to its safety features, performance, and ease of use.

Swift has continuously evolved since its launch, gaining widespread adoption among developers and tech giants like LinkedIn, Lyft, and Yahoo. Our skilled iOS developers at Indi IT Solutions rely on Swift to build dynamic, high-performance apps that meet contemporary user expectations.

If you're a start-up or business exploring options for iOS app development, here’s why Swift should be your go-to language, along with a breakdown of its top benefits.

8 Advantages of Using Swift for iOS App Development

Swift supports the development of apps across iOS, macOS, watchOS, and tvOS, making it a versatile language within the Apple ecosystem. Here are the top benefits IOS app development services offer to developers and businesses alike:

1. Efficient Memory Management with Automatic Reference Counting (ARC)
Swift incorporates Automatic Reference Counting (ARC), which helps manage memory usage effectively. This system ensures that instances are kept in memory only when needed and are deallocated automatically once they’re no longer in use.

Compared to Objective-C, Swift’s memory management is more refined and requires fewer manual processes, resulting in better performance and fewer memory leaks.

2. High Speed and Performance
One of Swift's standout features is its speed. The language is optimised to run as fast as C++, offering performance advantages for apps that require high-speed processing or real-time computing.

Swift's performance enhancements mean that apps built with it are faster and more efficient, which is especially important for complex, resource-intensive applications.

3. Full Stack Development Possibilities
Swift isn’t limited to client-side development. With server-side frameworks like Vapour or Kitura, developers can now build backend services as well. This creates opportunities for a full-stack Apple development experience, enhancing project coherence and development efficiency.

This dual-use capability makes Swift a great choice for companies looking to reduce dependencies and maintain code consistency across platforms.

4. Safety and Reliability
Swift emphasises safety by using features like type inference, optionals, and error handling. These tools help identify errors early in the development cycle, thereby reducing the likelihood of common issues such as null pointer exceptions.

Apps built with Swift are more stable and crash-resistant, leading to better user experiences and lower maintenance costs.

5. Cleaner Code and Simplicity
The language syntax in Swift is clean, expressive, and concise. Its readable structure is easier to understand, even for developers who are new to iOS development.

This clarity makes it easier to maintain and scale applications, eliminating complexities like semicolons or verbose type declarations, which are common in Objective-C.

6. Easy Integration with Objective-C
Swift can be integrated into existing Objective-C projects without requiring a full rewrite. This interoperability is ideal for businesses that want to gradually transition their codebase to Swift while continuing to use legacy Objective-C modules.

This hybrid approach ensures smoother upgrades and faster adaptation with minimal disruption.

7. Strong Open-Source Support and Community
Since going open-source in 2015, Swift has gained significant traction among developers worldwide. The growing community actively contributes to improving the language and creating libraries, tools, and resources.

This open-source model ensures continuous development, quick bug resolution, and access to a wide range of solutions for developers working with Swift.

8. ABI Stability and Binary Compatibility
With the release of Swift 5, Apple introduced ABI (Application Binary Interface) stability, which means that Swift code compiled today remains compatible with future OS versions.

This eliminates the need to recompile or rebuild Swift frameworks and apps for every Swift update, ensuring long-term project stability and reduced development overhead.

Final Thoughts

In summary, Swift offers everything a developer or business might need for successful iOS app development: speed, safety, readability, scalability, and strong community support. The added benefit of ABI stability ensures that projects built with Swift are future-proof and easier to maintain.
