Native Languages for IOS App Development

Mobile applications have historically been written in native languages. Lately, however, hybrid cross-platform frameworks are gaining market share. The recent swell of React Native’s quality has raised the question: Whether developers use React Native for mobile development rather than full native?

Multiple organizations in the field of information technology have embraced React Native, as well as Facebook, Pinterest, Skype, and Uber. Its widespread adoption is primarily driven by the convenience of its cross-platform nature and therefore the distinctive technological approach won’t to accomplish this.

Despite React Native’s success, many folks maintain that ancient native mobile apps are still the thanks to go. The proponents of native primarily cite its performance benefits and lustiness in comparison to hybrid alternatives. Trade-offs exist between each choices, and careful thought is needed once selecting between the 2 technologies. this text can weigh in on the matter by delving into what makes React Native therefore fashionable, and explore however it works below the hood. We’ll additionally check up on the execs, cons, and business impacts of every possibility, supplying you with the facts price knowing before creating a selection a technique or another.


React Native is written primarily with JavaScript and classified as a “hybrid” framework, that means that it’s platform-independent. This separates it from ancient apps written in native languages like Java or Kotlin for golem, and Swift or Objective-C for Apple. Instead, hybrid apps have one codebase that produces Associate in Nursing app which will run on each golem and iOS devices. The profit to the present is obvious: less code and connected supply in comparison to writing a try of native apps victimisation totally different languages. The drawbacks of hybrids are that they aren’t as performant as their native equivalents, and that they typically lack the power to form full use of a device’s resources.

Most hybrid frameworks that you just could also be aware of, like Ionic, Cordova, and Phonegap, place confidence in what’s called a WebView to accomplish their cross-platform capabilities. primarily, they introduce a webpage within a native app and hook into it to integrate with the underlying device. The matter with this is often that WebViews, particularly once hosting difficult apps, run into performance problems and produce other limitations.

React Native will things a touch otherwise. It doesn’t use WebViews, however rather a system that permits it to render native elements (hence the name) from its base JavaScript code. There’s a typical idea that React Native compiles JavaScript right down to native languages like Swift or Java, however that isn’t the case.

Now it’s obvious that the native iOS version appearance “cleaner”, however that isn’t very a priority here. What’s necessary is that we have a tendency to see there are not any WebViews in use, instead we’ve got a collection of native elements. The stack of views within the React Native example is just forming the fundamental responsive layout of the app, only if React Native uses Flexbox. The performance impact of this is often primarily nominal, and well worthwhile, only if the necessity for WebViews has been removed.

However, there are still some performance considerations price noting once analysing however React Native achieves this exploit.


In a React Native app, its JavaScript logic runs in a very dedicated thread, whereas the remainder of the app runs in what we’ll decision “the native realm”. JavaScript handles the business logic of the appliance, whereas the native realm renders the UI and manages device interactions. These 2 domains place confidence in one thing known as “the Bridge” to speak.

The JavaScript thread and therefore the native realm can’t have an instantaneous oral communication – they’re unable to concentrate, respond to, or cancel events and operations happening on the alternative facet. Whereas, they pass messages back and forth via asynchronous message queues, and this method “bridges” the gap.

For example, React Native could send a message to the native realm language “render this button”, to that upon receipt, native will. Later on, once the user clicks on this button, native dispatches a message to the JavaScript thread informing it of the action, triggering some associated application logic, which can then lead to a UI update being pushed into the queue for native then on.

Due to the disconnected and asynchronous nature of this suggests of communication, some performance problems will arise. Queues will get stalled, say as an example if the user is quickly scrolling through an extended and sophisticated list – several “user has scrolled” and “draw this new UI” updates fly back and forth. For the same reason, animations may also be a degree of concern. In reality, most of the time these sorts of performance deficits are negligible to the users but, they’re still one thing developers got to bear in mind of so that they may be designed around.

The good news is that initiatives like the JSI are in development to switch the Bridge with one thing higher. Developers may also use native modules to supplement their app with really native code to leverage device-specific practicality or address performance problems. this suggests that having developers aware of native on your React Native team may be terribly helpful.

React Native continues to evolve, given its quality and supporting community. It remains a high selection for developers Associate for those thinking of building an app. Try uCertifyiOS swift course for learning iOS development.
