In 2022, the global mobile market size was valued at 206.85 billion and is expected to grow at a CAGR of 13.8% from 2023 to 2030. With the constant rise in demand for mobile applications, there has been an upgradation in tools to make the development process easier and more efficient. Here, we are dealing with two such names popular in mobile application development Flutter and Swift. By the comparison between two Flutter vs Swift at the end of the blog, you will get a clear understanding of both.

What is Flutter?

One of the preferred cross-platform frameworks for mobile app development by developers globally. Flutter is an open-source, mobile application development framework. It is a relatively new launch but has gained popularity widely. It is developed by Google and the first release was in May 2017.

Benefits of Flutter for mobile app development

Hot Reload – This feature helps in making changes in the code without the need for rebuilding and instantly reflecting on the simulator.
Cross-platform – The prime advantage of using Flutter is it lets you build a platform-independent application, which makes it efficient and saves time.
Quick development – Flutter has tools like a compiler, editor, IDE, and rich library that help in faster development.
UI development – It offers a variety of pre-built widgets that lets us build user interfaces easily, with a different look and feel for different platforms.

What is Swift?

Swift is a programming language developed by Apple, Swift 1.0 was released in 2014. It is a modern, secure, and high-performing language. The syntax used by Swift is simple to understand making it easier for developers to learn. Swift is an open-source language. The language was continuously updated by the Apple team with each version released incorporating the requirements.

Benefits of Swift for mobile app development

Front-end and back-end – Swift is used for developing front-end and back-end both. Therefore code sharing and reusability are high, improving the speed of development.

Memory management – It uses a mechanism of automated reference counting which tracks the instances that are no longer useful and deletes them.

Rapid development – The syntax and grammar of Swift are easy and precise, which saves a lot of time for the developers. There are various tools for the developer which help in faster development.

Safety and Performance – It was built with a focus on its performance and outperforming the previously used language objective C. It uses the LLVM compiler framework that optimizes the code. It offers a strong typing system and better error handling which prevents the error and makes it a safer language.

Comparison between Flutter and Swift

Choosing between Flutter and Swift has been a challenging task for mobile application development. Flutter vs Swift has been a constant comparison and turns out to be confusing. Let us get some clarity by comparing them in detail.

1. Accessibility

This feature helps to enhance the user experience of the application for people with certain disabilities.

Swift – The already present UIkit framework supports accessibility API, which makes the application suitable for people with disabilities.
Flutter – For accessibility, Flutter doesn’t have any existing framework to support it.

2. Integration and development

Both are at par when it comes to integration and development.

Swift – Some APIs and frameworks help in efficiently building the application.
Flutter – It has many plugins, packages, and third-party services that seamlessly integrate with the application.

3. Application Size

The size of the application is an important factor the user checks before downloading it, therefore it is one of the concerns while the application development process.

Swift – The compiler in Swift helps in optimizing the application and also reduces its size. The XCode-derived server also keeps the application lighter.
Flutter – When compared to Swift, the size of the application built on Flutter is higher.

4. On-boarding Process

The onboarding process also decides how likely the developers will choose the language or framework for the next project.

Swift – The requirement is a macOS machine and Xcode to start with the application development, making the onboarding process simpler and easier.
Flutter – While working with Flutter, in addition to the Xcode, flutter tools are required and there are comparatively fewer tools available for iOS app development.

5. User Interface

The user interface of any application is majorly responsible for creating the first impression on the user’s mind.

Swift – It offers a complete iOS native user experience with the help of the API and frameworks to build an interactive user interface.
Flutter – It has a rich set of widgets, tools, and pre-built UI elements to develop an interactive UI. The flexibility of Flutter also lets the developers create a customizable UI.

The choice of technology depends on various factors. Our detailed article about Flutter and Swift is aimed to assist you in making your decision about picking the technology. Flutter and Swift both are high-performing and popularly used among companies globally.

Companies using Flutter are – Alibaba, The New York Times, Google Ads, and Google Assistant.
Companies Using Swift are – Facebook, Linkedin, Uber, WhatsApp, and Slack.
