Flutter – Kotlin – Swift: Trending Mobile App Development Platforms


Flutter, Kotlin, and Swift are three of the most popular mobile app development platforms out there. All of them have their own merits and disadvantages. If you’re having a hard time choosing one over the others, you’re at the right place.

Throughout this post, we will be highlighting key differences between these platforms. By the end of this blog, you will be able to decide which one is ideal for developing your mobile app. If that sounds exciting, let’s get going.

Overview & Market Share


Developed by Google, Flutter is one of the leading mobile app development frameworks which can help you develop beautiful, natively compiled applications for mobile, web, and desktop from a single codebase. Since 2018, it has been used by over 2 million developers and its community is growing in leaps and bounds.


JetBrain’s Kotlin is a modern, and concise programming language which can help you create feature-rich mobile applications that stand out. According to a recent survey by AppBrain, Kotlin is holding 76.60% of market share of the top 500 USA Play Store ranking. The framework powers over 129 Thousand apps and have been downloaded over 293 Billion up until now. Over time, it’s popularity is bound to grow.


According to the Popularity of Programming Language Index (PYPL), Swift ranks among the top 10 most popular programming languages out there. It was first released in 2014 and since then has evolved to become one of the leading mobile app development platforms boasting 55.5k stars on GitHub.

While all the platforms allow you to develop high-performing apps, they have subtle differences that set them apart. Let’s compare and have a deeper look.

Flutter vs. Kotlin vs. Swift: Detailed Comparison

With Flutter, you can create highly functional Android and iOS applications from a single code base by using a modern, reactive framework. Let’s look at a few significant features this platform offers right out-of-the-box:

Hot Reload

With Hot Reload, developers can see their changes in real-time. This feature enables them to make quick adjustments to the app and fix bugs instantaneously and in no time.

Cross-Platform Development

Flutter eliminates the need of writing code for multiple platforms. A single code can work for different platforms. Ultimately, this saves you time, energy and resources.

Accessible Native Features and SDKs

With Flutter’s native codes, platform APIs and third-party integrations, the development process becomes seamless and delightful. This means you will be able to access native features on Android and iOS while reusing popular programming languages like Swift and Kotlin.

Google Firebase Support

With Flutter, you can create scalable and high-performing apps by using Google’s firebase support as back-end.

Massive  Widget Library

Flutter allows you to leverage its rich widgets library to develop elegant UI quickly and easily. It has everything from structural elements to UI components that will help you make your app stand out from the crowd.

Apart from the above-mentioned ones, Flutter is jam-packed with many more useful features that will not only accelerate the app development process but save you plenty of resources.


Being a modern, and statistically-typed programming language, Kotlin offers both object-oriented and functional programming constructs. It can help you develop robust applications intuitively. Here are a few features that make this language stand out:

Minimal Coding

With Kotlin, you can create full-fledged apps with minimal coding. And because the language has a low learning curve, even a newbie developer can create apps using it. This means you can save both time and cost of development.


In the time when a user’s attention span is less than 8 seconds, your app must load faster and deliver a consistent user experience. And Kotlin’s lazy-loading feature takes care of this. Apps developed with Kotlin load faster and can prioritize primary resources to ensure a seamless experience.

Extension Functions

Also called the Standard Library Functions, Kotlin’s extension functions accelerate the development process by allowing developers to use pre-built modules that are basic parts of an object-oriented language.


A powerful language for iOS, macOS, and beyond – Swift is jam-packed with modern features that streamlines the development process. Let’s look at the top 3 features it offers:

Supports Playground

Swift has been added to Xcode. Thus, with playground feature, developers can write code and test it without making any changes to the existing code. What’s more, they can see the result in real-time without running the whole application. This saves them many hours in development and testing.

Fast and Powerful

Swift uses a high-performing LLVM compiler to transform its code into optimized native code. As compared to Python, Swift has made Object sorting significantly faster. Ultimately, this accelerates the development process while adding more power and performance to the apps.

Objective-C Interoperability

Swift is fully compatible with Objective-C. This means you can create a project that has files written in either language. With Swift, you can develop apps that have a mixed-language codebase. This makes the language versatile and useful.

Final Words

With over 3.6 billion smartphones out there, the mobile app industry is growing in leaps and bounds. In fact, people spend 88% of their mobile time on apps. You can leverage this opportunity by developing mobile applications that are both engaging and useful.

While all the three languages mentioned above have their own pros and cons, they are equally capable of developing high-performing iOS and Android apps that stand out from the crowd.
