Flutter Vs. Swift — Which One Is Better For IOS App Development Tool In 2021

Swift and Flutter are the two most popular technologies among businesses considering developing an iOS app. This article is for you if you’re looking for the finest tool for developing iOS apps.

Currently, both are the majority players in iOS app development. iOS apps can be created with Flutter and swift both, but how to select one that suits you and also android apps can be made with Swift too. The question is, which one is best? Currently, there are flutter app that are popular on iOS & Android and the same with Swift.

Globally, mobile apps generated $462 billion in sales in 2019. Google Play and Apple App Store, the two most popular app marketplaces, each has 2.9 million and 2.0 million apps, respectively. All of this is devoured by the world’s 4.5 billion Internet users.

So now, let us know each of them in a bit of a bit deep to understand why they are used and why they are popular.

What is Swift?


Swift is an Apple-developed programming language that replaces Objective-C. It’s used by Apple, but it’s also available to developers who want to make their apps for iOS devices. It will be possible to utilize it to construct Android and Windows apps starting in 2020.

Swift was first released in 2014 and has since undergone numerous updates and upgrades. On November 13, 2020, the newest stable release, 5.3.1, was released. Currently, companies hire swift developers for their iOS & Android app development.

What is Flutter?

It’s a “cross-platform user interface toolkit” that “allows code reuse across operating platforms like iOS and Android.” Dart is an object-oriented programming language that underpins this free and open-source platform.

Google is the creator of both Dart and Flutter. Dart was first launched in 2011, and Flutter was only added in 2015.

Flutter allows you to create two versions of your app at the same time. Being platform agnostic is a good thing. Flutter works on iOS and Android with a single code; while Swift is a programming language, it is also a creative writing language.

Why Should We Compare Flutter To Swift?

Why should we compare them if one is a programming language and the other is a toolkit or platform? Both are popular mobile and online application options. You can utilize either of these for your iOS app, and they’re both worth thinking about.

Now let’s compare Flutter Vs. Swift.

Flutter Vs. Swift: The Big Comparison

  • Speed of Coding

Swift is a fantastic and quick way to start developing an iOS application. Overall, it works well; however, it takes longer to reflect code changes. On the other hand, Swift developers believe that it provides a faster build time, particularly for the initial construction of an app.

On the other hand, Flutter comes with a slew of widgets, libraries, navigation, and testing tools to help you code faster. Flutter developers don’t have to worry about polishing UI elements because Flutter takes care of it. Furthermore, Flutter’s Hot Reload reduces the time it takes to observe recent code changes. As a result, changes are made more quickly. Again, the same application created in Flutter generally requires fewer lines of code than its Swift counterpart.

  • User Interface

Because Swift is an iOS-native language, adding any native iOS UI features is simple. Swift was used to creating this. The user interface will be as similar to that of iOS as feasible. However, you’ll have to start from scratch with every function and every aspect of the user interface.

Flutter comes with a large number of ready-to-use UI elements. To begin, name only the Material and Cupertino widgets. In most cases, Swift will not be required. Flutter-based UI should be indistinguishable from native Swift from the user’s perspective.

  • Performance

Swift, as the native language for iOS apps, offers a significant benefit. For tasks that require a lot of processing power, you should expect higher results (graphic effects, for example). Swift may be the superior option when it comes to juicing up the platform.

Flutter, on the other hand, does not lag behind. Dart first employs a garbage collector. Second, it’s AOT (ahead of time) compiled, allowing for fast connection with the device. Flutter will perform nearly as well as native Swift unless you need to make the most of the iOS platform.

  • Support and Community

Swift.org is where the leading Swift community congregates. Swift has approximately 830 contributors on GitHub, and over 2600 people are following the thread. On Stack Overflow, there are over 284 thousand questions tagged with the term “swift.”

Flutter’s figures appear to be similar. On GitHub, 3400 people are watching, with 770 people contributing. However, on Stack Overflow, there are fewer than 70 thousand questions labeled with the term “flutter.”

  • Stability

Even though these technologies are still in their infancy, they do not pose a significant threat to stability. Professionals who utilize them daily create and manage them.

Swift, as a native technology, should theoretically be more stable and trustworthy on iOS than Flutter. However, this is only true if you can discover and employ a top-notch Swift developer who knows how to get the most out of Apple’s products.

  • Documentation

Both Swift and Flutter have extensive online documentation.

Check out the Apple Developer documentation and Swift.org for more information on Swift.

Check out “Flutter. dev” for comprehensive and well-written documentation all in one location for Flutter.

  • Platform Maturity

Before launching Swift, Apple drew on years of Objective-C knowledge and has made numerous enhancements since then.

Before introducing Flutter, Google gathered their experience for a few years.

  • The Development Cost

Both are free and open-source, so you won’t have to pay anything more. Developers with more experience charge similar fees. If you consider an iOS app, the pricing difference isn’t significant. Flutter, on the other hand, allows you to make an Android version at the same time. And that would completely transform the game.

Top Companies/Applications Using Swift And Flutter

After reading the above content, if you can still decide what to choose, you can see what companies are using.

Applications That Are Using Swift:

  • Firefox for iOS is a web browser from Mozilla that, for security reasons, employs the native iOS language
  • Asana: It’s a SaaS-based project management web and mobile application (Software as a Service)
  • Lyft is a global firm that provides automobile rental, bicycle-sharing, and food delivery services using a mobile app
  • Applications That Are Using Flutter:
  • Philips Hue: This smartphone app allows you to sync your home’s smart lights to your media, depending on your mood or desire
  • Google Ads: It’s an online advertising platform also uses Flutter for various services
  • Realtor.com: It is the largest real estate website in the United States, and it uses cutting-edge marketing techniques.
