What is React Native?

React Native is an open-source framework developed by Facebook for building cross-platform mobile applications. It allows developers to write mobile applications using JavaScript and React, a popular JavaScript library for building user interfaces.

With React Native, developers can leverage their existing knowledge of JavaScript and React to create mobile apps that run on iOS and Android platforms. React Native uses a combination of native components and JavaScript code to render UI elements, resulting in apps that look and feel native to each platform.

Leading Apps Developed with React Native

Several leading apps have been developed using React Native, showcasing the framework’s capabilities and versatility.

Here are some notable examples:

1) Facebook:

The Facebook app incorporates React Native in various parts of its UI. While the app’s core functionality remains native, React Native is used for features like Marketplace and Watch.

2) Instagram:

Instagram, owned by Facebook, utilizes React Native for parts of its app interface, including Stories and Explore. This allows for efficient development and maintenance of these features across iOS and Android platforms.

3) Pinterest:

A popular visual discovery platform. Pinterest rebuilt its mobile app using React Native to streamline development and improve performance. The framework helps Pinterest maintain a consistent user experience across different platforms.

4) Walmart:

One of the largest retail chains in the world, Walmart, adopted React Native for its mobile app to deliver a smooth shopping experience to its customers. The framework enables Walmart to iterate on new features and enhancements rapidly.

5) UberEats:

UberEats, the food delivery service by Uber, leverages React Native for its delivery partner app. This allows for efficient development and deployment of updates to the app, ensuring a seamless experience for delivery drivers.

6) Discord:

Discord, a popular gaming communication platform, uses React Native for its mobile app. The framework enables Discord to maintain feature parity between its desktop and mobile versions while delivering a smooth and responsive user experience.

7) SoundCloud Pulse:

SoundCloud Pulse, the companion app for creators on SoundCloud, is built with React Native. The framework helps SoundCloud streamline development and deliver timely updates to its community of creators.

Differences Between Swift and React Native:

User Interface:

The first thing that comes to mind during the comparison of both platforms is User Interface.

This is because the user interface is the medium by which a user interacts with the system. Talking about the user interface of Swift, developers must develop the code from start.

So, they must edit the code for each different element. React Native uses JavaScript allowing you to run native elements without any polishing. Therefore, react native is easier to code for the user interface.

Also, it will not have any issues with different screen sizes. This means that you do not have to make a different user interface for different screens.

Stability:

Although React is one of the most popular languages, it does not produce native apps. Its work based on increasing the internal APIs and libraries for the application to work.

As such, it connects the man between the code and the platform. Swift, creates a native application that can take full advantage of the platform.

Swift works best when dealing with graphic effects and computational-heavy tasks. So, when it comes to zoom-out on the platform, the Swift is a good choice.

The cost of the development:

This is one of the important factors to consider when choosing a specific technology. Most of the challenges in this area can be solved with a simple graph showing increasing quality at a rising price.

But this is not true – especially considering the development of iOS apps. Swift costs about $80 to $300 according to the US estimate.

React Native uses about $70 to $350 by the same estimate. This difference is not so great when it comes to a single coder. They can accumulate when working with many on a large project or team.

So, when thinking about development costs calculated in hard currency. React Native is a little less likely to keeping the benefits it provides.

Coding speed:

Swift is a time-saving option for creating apps for the iOS platform. It simplifies app development by eliminating bugs.

At the same time, if your goal is to develop an app for iOS and Android platforms. And you do not want to develop two different mobile apps, take advantage of React Native. Also, for native iOS and Android apps that process copy-paste.

But if you want a specific iOS app then Swift is a good choice. This is because it is a simple programming language that is easy to code. 

Transform Your App Development with Swift or React Native

Above mentioned are some factors discussed to give you the idea about each platform.

Both platforms are best in their own places. To decide which platform to use for developing iOS apps, it depends on the type of product or project. It means that it depends totally on the customer requirements to decide what platform to use.

A Mobile App Development Company should consider all the points mentioned by the client. This will help the developers to decide whether they should use React Native or Swift.

One can choose Swift if the need is of iOS app only. For good maintenance and want to use the app for large period. For developing complex iOS apps.

Swift is better at graphic interface so it can be used when one wants to deal with games.

One can choose to React native if you want to develop app for other platforms as well like Android. For the effective and fast building of the app. It means that if the customer needs an app in a short span of time. 

Using the right choice will help the developer to build an effective and successful mobile app.
