How to Choose the Best Language For iOS App Development

It is no surprise that the number of smartphone users increases year by year. Hence, it is beneficial for your business to have a mobile app. Ideally, to have both iOS and Android apps. This will help you target and capture more customers instead of just iOS or Android users. If you are tight on budget, you may want to consider iOS app development first.

Generally, iOS apps have a shorter development time. Compared to Android apps, they are cheaper to build and maintain.

In this article, we will discuss iOS-dedicated, general, and cross-platform languages. Each iOS application programming language has its own strengths, trade-offs, and ideal use cases. We hope this helps you to choose the best language for iOS app development.

What is an iOS Programming Language?

An iOS programming language is a coding language used to build applications that run on Apple devices, including iPhone, iPad, Apple Watch, and Apple TV. Choosing the right iOS app language sets the foundation for your app’s performance and user experience. The two official languages backed by Apple are Swift and Objective-C, both of which give developers full access to native iOS features, hardware, and design systems.

Beyond Apple’s native stack, developers also use cross-platform languages and frameworks such as C#, JavaScript (with React Native), and Dart (with Flutter) to build iOS apps from a shared codebase that also runs on Android.

When you select a programming language for the iOS system, you are choosing the foundation that shapes your app’s performance, scalability, and long-term maintenance cost.

Quick Comparison: Best Languages for iOS App Development

Before we dive into each option, here is a side-by-side view of the seven languages covered in this guide. Use this table to shortlist the best language for iOS app development that matches your project type, team skills, and platform needs.

1. Swift

Swift is an iOS native language you can use to create applications for macOS, iOS, iPadOS, watchOS, and tvOS. It was introduced in 2014 by Apple as a substitute for Objective-C. Since then, Swift has become the most widely used iPhone app coding language among iOS developers.

Swift will be a great option if you want to develop an iOS app quickly and scale it later. The language guarantees a quick development cycle and the ability to produce safe, dependable code. Additionally, Swift is frequently updated. In other words, you can easily make any changes to your iOS app.

Pros for iOS app development:

• Fast development process
• Available as an open-source project
• Easy to use (especially for beginners)
• Stable
• Good Scalability
• Regular updates
• Safety and performance
• Automatic Memory Counting (ARC)
• Interoperability (especially with Objective-C)

Cons for iOS app development:

• A limited number of Swift developers
• Relatively new with limited resources and support compared to Objective-C or Java

2. C#

C# is a high-level, object-oriented, and all-purpose programming language. It was developed as Microsoft’s solution to Java. C# is closely integrated with the .NET platform, which serves as both a framework and a runtime environment.

C# is frequently used to create apps for Windows platforms. However, since the .NET Framework was made available for Mac and Linux operating systems, it is now possible for you to create native applications in this language for almost any platform, including iOS apps.

The creation of the Xamarin platform for developing Android and iOS apps was crucial for mobile C# development. It makes use of Mono, an open-source .NET platform implementation that is compatible with all of the main operating systems.

C# will be a good choice for you to develop an iOS app if you have a team of experienced C# developers and you intend to develop Android apps as well.

Pros for iOS app development:

• Easy iOS app development
• Open-source
• High performance
• Fast Speed
• Scalable and Updateable
• Automatic Garbage Collection
• Cross-Platform Support
• Rich Library
• Huge Pool of C# developers
• Popular

Cons for iOS app development:

• Not as flexible, given it is based on the Microsoft .NET framework
• Relatively hard to learn for beginners

3. Objective-C

Objective-C is the predecessor of the Swift language. It was built as an extension of the object-oriented programming language C with similar properties. It was developed in 1984 and is currently a general-purpose programming language that is still compatible with Mac OS and iOS, serving as the main iOS native language before the release of Swift.

There has always been a comparison between Objective-C and Swift in terms of readability, coding, execution time, code maintenance, and so on.

Objective-C is a mature iOS app programming language that might perhaps be a little outdated (the last version was released in 2016). You may notice that it can be difficult for you to find developers who can program in this language because of its declining use.

When it comes to iOS app development, you should only give Objective-C a thought if you want to build an app that can run on previous versions of iOS that Swift doesn’t support.

Pros for iOS app development:

• Stability and Maturity
• Dynamic typing

Cons for iOS app development:

• Relatively low development process
• Unavailable as open-source
• Hard to learn
• Low Security
• Limited functionality
• Lack of new updates
• Limited pool of Objective-C developers

4. Java

Java is a general-purpose, class-based, object-oriented programming language. What’s important, its code can run on every platform without needing to be recompiled.

Java is widely popular for creating Android apps. Furthermore, you may also use it to create cross-platform applications thanks to its flexibility.

But Java is not a popular option for iOS app development. If you already have an Android mobile application created in Java, you might want to think about using it to develop the iOS version as well.

Pros for iOS app development:

• Suitable for both native and cross-platform development
• Open-source
• Flexibility
• Functionality
• Secure
• Scalable and Updateable
• Automatic Garbage Collection
• Wide Pool of Java developers

Cons for iOS app development:

• Complex code
• Type-heavy language
• Poor performance
• Requires significant memory space

5. HTML5

HTML5 (HyperText Markup Language 5) is the fifth and currently the last major HTML version. You can use it to create a website by defining the meaning and structure of the content.

It is commonly used in conjunction with CSS and JavaScript, and these 3 are collectively known as the “big three of frontend” among developers.

Interestingly enough, using tools like Apache Cordova or the aforementioned Visual Studio for Mac makes it possible for you to develop iOS apps as well.

If you want to quickly develop a straightforward iOS app that can also be used offline, HTML5 is the best option. If you have HTML5 experts on your team who can create this kind of application, it would be wise for you to take this option into account.

Pros for iOS app development:

• Cost-effective
• Multi-platform
• Able to create offline apps
• Large consistency across several browsers
• Provide a good page ranking
• Wide pool of HTML5 developers

Cons for iOS app development:

• Does not allow building native apps
• Limited functionality
• Media licensing issues
• Need modern browsers to access
• Problems in Responsive design

6. Flutter

Flutter is a full-featured Software Development Kit (SDK) for mobile apps that comes with ready-to-use widgets and features. Google created it in 2015, and it was launched formally in 2017.

Using just one codebase, this tool makes it simple for Flutter developers to create aesthetically pleasing, natively compiled mobile, web, and desktop applications.

It’s important to consider Flutter, especially if you want to develop not just an iOS and Android app but also a desktop and web version.

What’s more, as this tool is built on the Dart programming language, it will be the best option for your business if your team members are familiar with it.

Pros for iOS app development:

• Time-efficient and cost-effective
• Fast development process
• Free and open-source
• Easy to maintain and develop new features
