Best iOS App Development Programming Languages and Platforms

In 2021, the internet was accessed by over 4.32 billion unique mobile devices, meaning that the majority of internet traffic was from mobiles. Ever since mobile phones were launched, the mobile market has kept growing at a rapid pace, with no signs of a slowdown. Apple launched the first iPhone in 2007; today, there are over 1 billion iOS devices in the world, and more than 1.5 million apps in the App Store. This shows how important iOS development is.

It is imperative that the right iOS app development language is selected so that the development can proceed smoothly, the app performance is good, and it’s easy to maintain.

What Is iOS Programming Language?

iOS programming languages are the ones used to make apps for Apple devices like iPads and iPhones. The most popular iOS language is Swift and SwiftUI, followed by Flutter, React Native, Objective-C and other languages. 
Swift UI has the number one spot, but Objective-C is not done and dusted yet. It’s used whenever legacy codebases are involved, for existing or new projects. All iOS developers can use both languages in the same project, so that they can have a smooth transition, gradually shifting to Swift, rather than a sudden change.

Requirements for the iOS App Development Process

What are the things you need to have before you even start coding?

  • A Mac with the newest macOS version
  • XCODE, the IDE for macOS (free download from App Store)
  • Active Apple Developer account, charged at 99 USD annually

These three work in combination; you need to be an active member of the Apple Developer program, and your apps must be signed and published by Xcode; since it only runs on macOS, which only runs on Apple Mac computers. Xcode includes a code editor, UI designer, asset catalogue and testing engine; in short, everything that you would need to develop iOS apps.

The Major Benefits of iOS Programming Languages For Businesses

iOS programming offers innumerable benefits for businesses; let’s look at the key points:

  • High Performance - as they are compiled into native code, they offer top notch performance
  • Constant Updates - Swift is continuously updated by Apple, which means apps will keep supporting the latest iOS versions
  • Wider Reach - using languages to build cross-platform apps increase user base as compared to building for a single platform
  • Cost-effective - using a single code across platforms reduces effort and resources required to build and update apps in both platforms


Apple continues to dominate the smartphone market; as such, the demand for iOS apps is only going to increase. Don’t expect a slowdown anytime soon. This means there will be a huge demand for iOS app developers as well. Choosing the right programming language can help you streamline the development process, regardless of whether you build apps exclusively for Apple or for cross-platform use. 

Objective-C and Swift are the best suited for complex native apps in iOS. If you’re looking for versatility, JavaScript or C# may be ideal. If you already know these languages, it’s even more helpful, since it means that you don’t have to learn another language like Swift or Objective-C.


Swift is currently the most popular choice among iOS developers, as it’s the native language for iOS development and is considered the best programming language for app development for Apple devices. If the focus is on native iOS development and high performance, Swift might be the better choice.
Swift is the ideal language to develop iOS apps. If you’re looking to develop apps to run on older versions of iOS, Objective-C is also a good choice. 
Generally, iOS apps are written in Swift, as it is capable of using the iPhone features to the max. However, JavaScript and C# are mobile app development languages that can also be used to create iOS apps depending on what you are looking for.
It can take from six weeks to six months depending on the complexity of the app, features required, expertise of the team building it, resources available, and so on.
