iOS Development

User-friendly apps are very popular these days. Advanced mobile technology has hastened this pace and it has made it simple to develop iOS and Android apps. Before you decide to develop your app, it is incumbent upon you to choose the framework that suits your app well. Swift is a programming language introduced by Apple and Flutter is launched by Google. The former is used for iOS development and the latter is used both for Android and iOS Development. In this write-up, we will figure out the best one for your needs by making a comparison of these frameworks.

What is Swift?

Swift is a programming language released by Apple in 2014 for iOS development. Objective C is the predecessor of Swift. Although it is created by Apple, it is a free and open-source program that could be used by developers to develop their own applications on iOS-powered devices.

From 2020 onwards, it could support the development of Android and Windows applications with the help of its extension, SCADE.

Let us see the advantages given by Swift

  • Outstanding Documentation
  • Advanced functionalities
  • General purpose and open source
  • Best readability of the code
  • Scaling made simple by dynamic libraries

It helps the developers to reuse the code across various operating systems such as iOS, Android, Mac, Windows, Google Fuchsia, and web apps from similar source code. As DART was released in 2011, Flutter joined in 2015. Flutter allows you to develop two variants of your application at a time. Thus, a single code could be used for both iOS and Android.

Let us see the benefits given by Flutter

  • Free and open source with a large user base
  • Excellent documentation
  • Faster

What is Flutter?

  • Flutter is Google’s mobile Software Development Kit (SDK) which is derived from DART, an object-oriented programming language. It is also an open-source platform.
  • Support for legacy devices
  • Widgets make it simple to create interfaces

Flutter Vs Swift: Which is the best choice for iOS Development

Here we look into some factors on the basis we compare these technologies.


The user interface is an important part of mobile app design. It is really significant as to how well the app gets along with the platform’s native features and functions in the case of Swift, it is easy to implement any native features for the interface as it is a native language. Here, every feature should develop from the start. When it comes to Flutter, It designs with ready-to-use elements. Normally, any backup or support is not important from Swift. It looks similar to Native Swift.

Speed of coding

Speed is critically important in app development, especially in coding. The speed of coding determines its TTM (Time to Market) along with cost-efficient.

Swift is a great option to develop an application from scratch. It works well. But making changes in the code takes more time and effort. Developers say that the time taken for development reduces and enhances the application development efforts easily. The initial development of an IOS application is simple with Swift.


It shows how the app is efficient regarding the platform and device.

For better performance of tasks that require more computational power and efficiency, Swift can be a dependable option. If you want to fully use the true capabilities of the platform, Swift is the right choice.

We are not saying that Flutter is not far behind in terms of performance. Primarily, its object-oriented programming language, Dart, uses the concept of the garbage collector. Then it is compiled ahead of time which helps to have quick and speedy communication with the devices.


A reliable experience for the user is the result of stability. Although these technologies are the latest in the line, they do not show any problem regarding stability. In fact, it is designed, developed, and monitored by professionals who are updated on it daily basis. On record, Swift offers more stability on iOS as it is a native technology. But that is realized only with the help of well-versed people on it.


 Well, documentation immensely supports processor development. You can access the thorough documentation of both Swift and Flutter through their official websites. Go to swift.org and Flutter. dev for Swift and Flutter respectively.


When it comes to a business entity, the overall cost of development is critical. Since both are open-source platforms, you are not required to use your wallet on them. If you consider developing only an iOS application, the cost difference won’t be much bigger.

But Flutter helps you to develop an Android version at the same time. That is highly cost-effective.

A pool of talents

A talented pool of developers is critical to the success of these frameworks. In fact, a good pool of talents is at your disposal both for Swift and Flutter. But Swift is much more popular compared to Flutter even though Flutter enables us to create both Android and iOS applications at a time

Wrap up

Whether to opt for Swift or Flutter? In fact, it is quite puzzling and a single and straightforward answer is a bit difficult for this question. It is a well-known fact that many companies at present use both these technologies and deciding to make your choice is reliant on your individual requirements.

So just keep in mind the crux that Swift helps you to develop iOS applications and Flutter enables you to create both Android and iOS versions at the same time.
