What is react native?

Released and maintained by the social media giant – Facebook in 2015, React Native is an open-source JavaScript programming framework. The key objective behind introducing this framework was to facilitate cross-platform app development and boost the process of mobile app development.

Simply put, React Native lets you use a similar code base to develop native-looking apps for both Android and iOS platforms. This feature aids in decreasing the development time required to create cross-platform applications, ultimately resulting in significant cost savings for businesses seeking to build their applications across multiple platforms.

Backed by the JavaScript library, the most used programming language, React Native lets developers use up to 70% of the same code across different platforms such as iOS, Android and Windows. So, if your business plans to launch a cross-platform app in the shortest possible time, React Native is your go-to choice.

With our understanding of React Native established, let’s talk about the Pros and Cons of the framework in detail before we compare React Native Vs Swift.

Pros and cons of react native

Undoubtedly, React Native has gained immense popularity among iOS app developers and individuals who are considering investing in iOS app development. However, this app development framework has its limitations.

Before investing in your next iOS app development project with React Native, take the time to review the pros and cons of this framework to maximize your investment.

The pros of react native for ios app development

Here are the pros of using React Native for iOS app development:

• Superior Performance: As native apps are built for a particular operating system, they take maximum advantage of the processing speed of the device. In addition to high-speed functioning, they also ensure seamless user experience and flawless performance with a well-designed UI.
• Live Reloading: This feature enables React Native app developers to immediately visualize their code in a preview window. Developers can see real-time changes and avoid the need for redevelopment or redeployment of the app. This results in time-saving, better code quality and higher productivity.
• Extensive Library Support: When comparing Swift vs React Native, the former has almost 33,000 libraries and packages, compared to Swift’s mere 3,800 packages. While the figures alone don’t guarantee the quality of the language or its framework, they demonstrate the community’s dedication and passion to contribute to the technology’s future development.
• Reduced Time to Market: React Native’s platform independence leads to reduced development cycles and faster time-to-market. By writing a single codebase, and with a few native tweaks, deployment on both platforms is possible.
• Create Feature-rich Apps: React Native’s easy integration of native device features and third-party libraries allows for the creation of feature-rich mobile apps. For example, a React Native app can use device features such as GPS, camera and Touchscreen, and can be easily integrated with VR, AI, IoT and AR technologies to build groundbreaking apps.
• Faster Development: Features like using a common codebase across both platforms and hot loading help React Native app developers reduce development time.
• Cost-Effective: React Native lessens the cost of iOS app development by minimizing the need for native developers and permitting the use of open-source libraries. This can lead to substantial savings in development costs.
• Easy to Debug: React Native offers developers a selection of essential debug tools, including the Flipper tool and React DevTools, which can significantly accelerate the bug detection and fixing process.
• Quick App Updates (QAU): This React Native feature allows developers to eliminate the conventional approach of releasing app updates for the users and deploy their app updates directly in user devices using OTA (Over the air) feature.

The cons of react native for ios app development

Here are the cons of using React Native for iOS app development:

• Complex Design for Custom UI: Both iOS and Android platforms have their own set of guidelines for publishing apps in their respective app stores. This turns into a huge problem for React Native app developers, as they find it challenging to create a high-quality custom user interface in their app development.
• Testing is more Intensive: When we compare React Native vs Swift, building multi-platform apps is certainly faster in React Native due to its script-sharing feature. However, the testing process in React Native is extended. Testing React Native apps requires more precision and effort since errors are more likely to arise on both platforms.
• Limited Wrappers: Integrating native modules, components, and APIs into projects may require developers to write custom wrappers, and this process will demand more time.
• Security Challenges: React Native, a popular choice among iOS app developers, has security challenges due to its open-source JavaScript framework. The loosely typed language allows variables to contain anything, making it a potential security threat. Developers building financial and banking apps must add security patches to address these issues.

On-demand apps developed with react native

The following are the most well-known on-demand applications created using the React Native framework.

• Bloomberg
• Facebook
• Instagram
• Pinterest
• Spotify
• Walmart
• Uber Eats

React Native was preferentially used to develop these top-rated apps with millions of users, which offer various services such as food delivery, transportation, and accommodation, due to React Native’s ability to create user-friendly and high-performing cross-platform apps.

What is swift?

Back in 2014, Apple rolled out its new programming language, Swift, to take over the reins from its predecessor, Objective-C. Swift is a versatile, modern and general-purpose programming language.

Thanks to its versatile and user-friendly characteristics, Swift has become the go-to choice for constructing top-notch, native iOS apps across the full suite of Apple devices; from iPhones and iPads to Apple Watches, TVs, and Macs. Swift’s language is optimized for clarity and concision, employing state-of-the-art features like type inference, automatic memory management, and generics to enhance its readability and usability.

Swift’s knack for harnessing native hardware features inherent in Apple devices sets it apart as the primary choice for developing first-rate iOS apps that are both secure and feature-rich and steadily cementing its reputation as the best tool to build cutting-edge apps in the Apple ecosystem.

The comparison of Swift UI vs React Native arises from their significant differences as Swift is a native language by Apple, while React Native utilizes React components and JavaScript to create cross-platform app experiences.

The pros and cons of swift

Sure, there are pros and cons to consider when choosing between Swift vs React Native. Let’s take a look at the Pros and Cons of Swift development.

Pros of choosing swift for ios development

Here are the pros of using Swift for iOS app development:

• High Speed: Using Swift, app developers can create apps up to 3.4 times faster than those coded in Objective-C. Swift achieves this through efficient memory management and modern compiler technology.
• Security: Swift prioritizes security, with features including type safety, automatic memory management, and strong typing impressively enhancing the security measures of iOS applications.
• Expressiveness: Swift’s easy-to-understand and expressive nature is due to various aspects, including its clean and simple syntax, closure support, and the use of modern programming concepts, including protocols and generics, leading to clear and concise code development.
• Community: A vast community of developers actively supports Swift, with numerous resources available to help developers in learning and using Swift through the Swift website, Swift forum, and Swift GitHub repository.

Cons of choosing swift for ios development

Here are the cons of using Swift for iOS app development:

• Smaller developer community: Due to being a relatively new language, Swift has a smaller developer community than some other languages. This may create difficulty in obtaining assistance or support when confronting any development obstacles.
• Only for Apple platforms: Being a native development platform, Swift is restricted to the Apple ecosystem and cannot be used on non-Apple devices. Therefore, creating a standard app that runs on both Android and iOS platforms would necessitate the development of two distinct applications.
