iOS App Development: Languages You Can Use For Development


When it comes to iOS app development, the languages that come to mind are React Native, Objective-C, and Swift. While both are capable of making a functional iOS app, one has a slight edge over the other.

As someone who is looking to develop an iOS app, you might be perplexed as to which is better. Each language is unique and has its own advantages that should not be overlooked. Let us help you solve your problems by comparing these technologies and assessing their usefulness. 

Here is the comparison between Swift, Objective-C, and React Native. 

iOS Application Development Language

There are about three programming languages that an iOS app development company will suggest to you for your project. These are the best options that will offer you app unique features depending on what type of app you want.


Swift (owned by Apple) is officially the primary programming language of choice when developing iOS applications. As of 2015, Swift became an open-source technology meaning all iOS developers were free to use the technology. 

Swift finds use in iOS application development and the development of applications for tvOS, macOS, watchOS, Linux, and zOS. 

Use Cases 

  • Multi-platform applications
  • Apps requiring complex and customized user-interface
  • Native iOS apps
  • Tp develop applications that have long-term updates and maintenance requirements 
  • Applications for enterprises having high-security needs 


Understandably, Swift is the primary iOS development language meaning that it has to offer seamless performance. 

Swift is able to rapidly run complex applications courtesy of the LLVM compiler framework. The LLVM acts to convert swift code to native code, facilitating access to the device’s hardware and APIs. Again, the simple syntax of Swift assists its efficiency as an iOS programming language. 

Code Maintainability 

When talking about the code of Swift, the code is lightweight and expressive. The addition of a type interface improves clarity and prevents the chance of cluttering. These features make it relatively easy to manage and maintain code. 

User Experience

Swift programming language is a native iOS application development tool that is elemental for creating impressive user interfaces. SwiftUI is another framework that will work well to give your iOS app exciting features. These include; dark mode, widgets, dynamic type, and more. 

Community Support

Swift has not been around for decades but its popularity is helping it gain supporters from around the world. Plus, being Apple-run and the main iOS development choice will have Swift community become one of the largest in no time at all! Because Swift is catching fire so quickly, getting developers with an impressive portfolio will not be an issue.


A superset of the C language, Objective-C was the preferred iOS development language and still is a good option. It is known for its object-oriented capabilities. 

Use Cases

  • If the application has already been written with Objective-C or requires Objective-C libraries
  • Require well-supported programs
  • Stability is more important than performance
  • When your developers are proficient in C++ since Objective-C and C++ overlap


Objective-C dispatches lookups dynamically at runtime which can be very slow. This makes the performance of Objective-C much slower than competitors. But, this by no means makes it the slowest iOS development language and definitely not a reason to exclude it completely.  

Code Maintainability 

Maintaining Objective-C iOS applications will require your developer to maintain two sets of code. Only through this will efficiency increase and development time decrease. The Objective-C language is built on the C language and carries the same conditions. This includes symbols, lines, semicolons, parentheses, “if” and “else” statements.  

User Experience

Objective C focuses on answering the question rather than perfecting the answer. User interfaces are not as customizable and functional as say, Swift. This may have something to do with the age of Objective-C and the market in which it was first launched. 

Community Support

Objective-C has been around for a long time, enough time for it to develop a large community of developers. That said it is safe to say this programming language is well documented and you will not face any issue in finding a development team for your project. 

React Native

React Native is an open-sourced language that is based on JavaScript. Because of this, almost 70% of code is interchangeable between Android and iOS. This is a boost for this Facebook-supported programming language that is free to use! 

Use Cases

  • Cross-platform apps 
  • When requiring apps with reusable components
  • If you want apps that work well with synchronous APIs 
  • Rapidly developed prototype applications
  • Applications with relatively simple UI 


React Native applications consist of a JavaScript thread, a Native thread, and a connecting bridge. Unfortunately, the JavaScript thread can only process a certain number of requests. Beyond this, the applications will start to lag, leading to noticeable stuttering.  

Code Maintainability 

React Native is a young programming language, making it less stable than Swift and Objective-C. Debugging React Native code is a job that not many developers look forward to doing. But, its cross-platform support is a reason to overlook the difficult code maintainability. 

User Experience

UI and UX tools used by React Native are constantly changing with every update released. This makes it hard for React Native developers to make the UI experience consistent. In iOS apps, Style Design is used to make UI design that will appeal to users. 

Community Support

Since its launch in 2015, the React Native community has been growing and the number of contributors is steadily rising. Being open-source, contributors from around the world (individuals or groups) can contribute. Since React Native is new and well-supported, you can expect constant updates. 


Entering the iOS app development market is definitely a budding opportunity for an investor willing to try something new and exciting. But, when it comes down to choosing the right programming language, there is no ‘right and wrong.’ 

Instead choosing the programming language to use will be made based on your requirements. Either way, Swift and Objective-C make the best language for iOS app development.
