What Language Are iOS Apps Written In?

In the ever-expanding world of mobile applications, iOS has emerged as a dominant force. With over one billion devices running iOS and the Apple App Store boasting over 1.6 million apps, the potential for developers in the Apple ecosystem is undeniable. But what language are iOS apps written in? Let’s explore the options and find the best fit for your next project.

The 6 Best iOS Development Languages

1. Swift

When it comes to developing native iOS apps, Swift is the go-to programming language. Created by Apple, Swift is designed to make app development in the Apple ecosystem faster and more efficient. With frameworks like Cocoa, Cocoa Touch, CloudKit, and AVFoundation, Swift offers a range of tools to enhance the app-building process. Ranked 11th in popularity according to the Tiobe index, Swift is a powerful language for iOS development.

Best use case for Swift: Swift is ideal for building iOS apps quickly and with scalability in mind. It offers excellent performance, as it eliminates the need for code interpretation on iOS platforms.


2. C

Initially a Microsoft creation, C# has become a popular choice for iOS app development since the introduction of Xamarin. Xamarin is a hybrid app development framework built on C#, allowing developers to share code between different target platforms. Ranked as the 5th most popular programming language, C# is a versatile option for building iOS and Android applications.

Best use case for C#: C# is the language of choice if you plan to develop apps for both iOS and Android platforms or if you already have a team of C# developers.


3. Objective C

Objective C, an extension of the C programming language, has been a staple for iOS development since its inception. While relatively outdated compared to other languages, Objective C still serves its purpose for building iOS applications. It is recommended for developers who need to support older iOS devices that are not compatible with Swift.

Best use case for Objective C: Use Objective C only if you are targeting older iOS devices. Otherwise, Swift is the better choice for current and future iOS apps.

4. Java

Java, a popular and mature programming language, can be used to build both iOS and Android applications. With over 9 million current developers, Java is a reliable and fast cross-platform language. Though not the most popular option for iOS development, it can be utilized through frameworks like Codename One.

Best use cases for Java: Java is suitable if you already have an Android app and want to port it to iOS with minimal effort. For native iOS development, Swift is the recommended choice.


5. JavaScript

Web technologies, including HTML, CSS, and JavaScript, offer an alternative approach to iOS app development. By utilizing frameworks like Apache Cordova or React Native, developers can create web apps and wrap them in containers for iOS platforms. JavaScript, ranked 7th in popularity, serves as a fundamental language in this context.

Best use cases for JavaScript: Choose JavaScript if you want to develop web apps for iOS or if you are comfortable with HTML, CSS, and JavaScript. React Native is a suitable option for hybrid applications.


6. Dart

Dart is the programming language behind Flutter, a hybrid app development framework created by Google. While not as widely adopted as other options, Dart provides a straightforward way to build fast, responsive, and visually appealing apps. Flutter includes Google’s material design philosophy as a default, making it an excellent choice for iOS and web app development.

Best use cases for Dart: Dart is ideal if you want to develop both iOS and web app versions simultaneously. Flutter simplifies the process with its built-in material design.


Benefits of iOS Programming Languages for Businesses

Choosing the right programming language for your iOS app involves considering the benefits it brings to your business. Here are a few key points to help guide your decision-making process:

1. Project Diversity and Developer Flexibility

Opting for a language that allows developers to work on various projects beyond iOS apps can benefit your business. This not only provides developers with new opportunities to showcase their skills but also makes them flexible in tackling different challenges.

2. Cross-Platform Development

If your app is intended for multiple operating systems, hybrid app development frameworks like Xamarin, React Native, or Flutter are viable options. By targeting other platforms, you can significantly expand your user base and increase app adoption rates.

3. Web Availability

Web apps are popular companions to mobile apps, providing users with versatile access. Using web technologies such as HTML, CSS, and JavaScript, or frameworks like React Native and Flutter, allows you to create apps available across various devices. This broadens your app’s appeal and enhances user retention.

4. Native Functionality, Performance, and Feel

For businesses focused solely on iOS app development or aiming to leverage native functionality, Swift is the language of choice. With Swift, you can tap into iOS platform features and create high-performance apps that align seamlessly with iOS users’ expectations and preferences. It ensures the delivery of top-notch products and leaves users craving more.

What to Consider Before Building an iOS App?

Before diving into iOS app development, it is essential to consider a few crucial factors:

1. Know Your Target Market

Understanding your target audience is vital in designing an app that meets their needs and expectations. Conduct market research to identify your target users based on factors such as gender, age, location, and preferences. This knowledge will enable you to tailor your app to their specific requirements and run effective ad campaigns.

2. Identify the Problem You Are Solving

Ensure that your app solves a problem or addresses a need in the market. This serves as the foundation for its success. Determine if you have competitors and find your unique selling proposition.

3. Define the Scope of Your Application

Clearly outline the features and capabilities your app will offer. Establish a strong foundation by covering the essential functions. You can expand the scope in the future, but starting with a well-defined scope ensures a solid start.

4. Choose Devices to Support

Consider which iOS devices your app will support based on their compatibility and the functionalities your app requires. Determine the iOS versions you will target and the languages compatible with the chosen devices.

5. Evaluate Your Development Capacity

Building an app requires a skilled team of developers. Assess your capacity and determine if you have the necessary talent in-house or if you need to hire remote developers. Frontend and backend developers, UX/UI designers, graphic designers, QA developers, and project managers may be necessary to bring your vision to life.

Final Thoughts
