When it comes to building an application for iOS, one essential question arises. This question is about developing a native app on Swift or a cross-platform solution on React Native.
Moreover, React Native vs Swift is a topic of confusion among many iOS developers. Many of them say that it is better to use Swift for iOS apps. However, in some cases, React Native may seem a better choice. This post will briefly explain exactly what is the difference between React Native and Swift when it comes to iOS application development. We will also share their basic pros and cons to help you choose the right solution.
Swift is a general-purpose multi-paradigm programming language. It was designed by Apple with the aim to create iOS-powered devices and all the following ecosystem. With the help of Swift, developers are also able to build apps for Apple computers, AppleWatch and Apple TV digital media player.
Nowadays Swift is distributed on Apache License, which makes it available for the community. It was launched in June 2014, seven years after the first launch of iPhone.
Mobile apps are becoming the attributes of lifestyle and establishing connection with users. When people install apps, brands are constantly in their pockets or under their hands.
A typical mobile user checks his or her device no later than 15 minutes after getting up even before brushing teeth. So, having mobile apps seem like a must. When it comes to building the app and cross-platform mobile development, developers face real costs, sometimes huge ones.
Companies that are able to cut costs without losing quality may have a huge gain. They often need to address the needs of both iPhone and Android devices and prepare two separate software pieces designed to the most sturdy form of cross-platform mobile app development. Comparing React Native and Swift possibilities is accurate as the optimization may come with costs that are not to accept easily.
Choosing the framework for your needs, pay special attention to the following criteria:
Swift has clean syntax, which makes it easier to read and write and this is its main advantage. You will need fewer number of code lines needed to implement an option on Swift (compared with Objective-C). Swift code looks like plain English that makes writing code more natural.
Dynamic libraries are the executable code, which allows Swift applications to hyperlink the changes/updates that new versions of Swift language deliver over time. They are included in the app package deal at some level in the download.
Objective-C can not evolve without C evolving first. Swift does not have these dependencies and it makes it easier to maintain it. Swift combines the Objective-C header (.h) and implementation files (.m) into a single code file (.swift).
Applying Swift, developers are able to spend more time creating app logic and improving the code quality, comments, and features that are supported.
Nowadays developing a secure app is one of the major priorities. Swift’s language and synaxis exclude some mistakes possible in Objective-C. The stability of Swift makes it less likely to make mistakes and adds extra control during development.
Swift is also known for its speed advantages during development that allows saving on costs. A complex object sort will run significantly faster than an implementation of the same algorithm in Python, for example.
As Swift was announced as open-sourced 2015, it has the potential to be used across different platforms and for backend infrastructure. The open-source nature of Swift means that Apple can get feedback from the community for making improvements on a consistent basis.
Swift may look unstable, especially with the consistent changes in the newer Apple versions.
Swift was introduced in 2014. However, the recent updates brought stability across Apple’s platforms, renewed documentation, and backward compatibility of Swift versions. It is a huge step toward making Swift a more mature language.
Swift community is growing fast, however, it still seems smaller if compare with any other open-source language.
Swift can be utilized in the apps that target iOS7 and later. You can not use Swift for legacy projects working on older versions of the operating system.
Thanks to the only one code written, React Native means two times lower costs for creating and only one dev team to pay. About 90% of the codebase can be used across both platforms. The exact savings that react Native provides depend on the number and complexity of platform-specific features.
React Native is open-sourced that gives developers an opportunity to use the frameworks and its libraries literally for free. All the functions are under the MIT license that puts only limited restrictions on the software reuse and grants legal protection to the developers.
Three years after its development, React Native has gained recognition of some of the world’s giants as Tesla, Instagram, Pinterest, Skype, and many more. Facebook invests considerable resources and time in enhancing the framework and releasing regular updates.
React Native supports over-the-air updates. If you want to make minor changes quickly, you bypass the tiresome market stores’ approval process. what you need is to send an updated version out. Users download it, and the app upgrades.
The mobile apps in Swift and React Native are almost identical in speed and physical appearance.
There are few real React native experts. You may find more Swift resumes on the market. It means that it is not so easy to gather your own team of React Native developers.
React Native can apply the platform-specific features, but it requires native bridges to access them (that are written in native languages).
It is good to have Having various solutions to typical problems, but some of them can suddenly present unpleasant surprises of their own.
Programming is often based on a paradigm of building new things with old tools. Old stuff doesn’t leave the field, even when new programming languages emerge.
Developing with Swift boosts performance and enables developers to leverage all the possibilities provided by iOS.
