You have picked React Native to construct cross-stage native apps on the two iOS and Android. The most significant advantage here is that the code is shared across the stages. Code once, and it deals with the two iOS and Android. 

In any case, there are good contrasts between iOS and Android that you need to handle as a React Native App Development. There will never be an ideal one size fits all arrangement, which implies you need to tailor a few pieces depending on the stage.

Tools Used in iOS and Android


If you are building your React Native app, utilizing the React Native app development, you will utilize various apparatuses for iOS and Android.

  • IOS – The primary device you should fabricate iOS apps with React Native is Xcode. It introduces the iOS test system and every one of the essential apparatuses to assemble your iOS app. You additionally need a Mac OS to work with Xcode. This implies you need a Mac OS assuming you need to construct iOS apps with React Native or iOS apps.
  • ANDROID – While building Android apps with React Native, you will see we need a unique toolset. The principal thing you would require is to introduce the Java Development Kit (JDK). The apparatus that is practically identical to Xcode for Android will be Android Studio.

Native Components

When you begin creating apps with React Native app development, you will see that specific segments appear to be unique on iOS versus Android. This is totally anticipated. Since React Native interprets the parts into the relating native component of the stage, you will see the cross-stage contrasts. 

A definitive guide to this is the date picker part. The native iOS date picker appears to be altogether unique from the native Android date picker.

Stage-Specific Styles

React Native backings styling dependent on stage. You can use it in circumstances where you might require unobtrusive contrast in styling dependent on the scene. For example, if there is a distinction in the native segments and you need to style iOS and Android unexpectedly, you can utilize the Platform API. 

The foundation stone is set to red for iOS and green for Android. Notice the other styling-like flex are shared across the stages. You can likewise utilize the Platform API to decide the adaptation of the iOS or Android gadgets.

Stage-Specific Files

Suppose you have essentially unique code for certain parts relying upon the stage, then, at that point, React Native gives you an approach to isolate them out into various records. Then, when you are prepared to import the segment, you can do so by giving the element’s name without giving the expansions. 

React Native is sufficiently keen to recognize the gadget and render the part in a like manner. If you are utilizing an iOS device, it delivers the segment with the ios.js augmentation and works the same way for Android.


Respond Native empowers a solitary JavaScript codebase for two distinct stages. This implies that it isn’t only simpler to keep up with the application by having a similar improvement measure for the two stages and reusing a similar code. However, it likewise requires fewer assets because there is no requirement for independent iOS and Android groups. Brain Stream is an iOS Application Development Services Company in Sydney.

In any case, this advantage accompanies an expense. Notably, Android and iOS have specific plan rules. Human Interface Guideline for iOS and Material Design for Android have a significant portion of contrasts, so if the undertaking prerequisites direct that these particular OS necessities ought to be followed for every native stage, React Native app development should compose explicit stage code, which invalidates the point of the single codebase.

The Programming Language 

React Native depends on React.js, which is written in JavaScript. This is a significant benefit of the way that JavaScript is such a broad and well-known language that it’s exceptionally difficult to come by a pre-owned developer it eventually in their profession. 

While Java and Swift/Objective-C are specifically accumulated dialects, JavaScript is deciphered and frequently called an untyped language. This implies that your factors can be anything whenever, and a compiler won’t help you, so in case you’re not extra cautious while composing your apps, the floor is cleared for JavaScript repulsions to result. 

On the other hand, when simple native apps have more control of the factors and the rationale of the app is more unsurprising, JavaScript depends on the software engineer’s insight, Lint instruments, and programmed tests.

User Interface

React Native’s approach to organizing UI is Flexbox, which is now exceptionally famous in web development and empowers the engineer to make a responsive web or mobile UI without any problem. Accordingly, it is an innovation that matches Android’s XML/Constraint design approach, or iOS’s Storyboard/XIB/Coding with UI libraries, for example, the Neon approach.

However, one extensive benefit that local portable has is that you approach all the local APIs like Camera, Touch ID, and GPS, just as instruments for making movements and complex UI. There is no centre layer, and you can exploit everything the portable stage has to bring to the table. Respond Native doesn’t dominate at making complex UI and liveliness. It has the Animated API, which is a flawless arrangement yet is a long way behind the local capacities.

Native Modules

While React Native can deal with many cross-stage use cases, it is outlandish for it to cover all the local portable ground. This implies that there will consistently be a requirement for local modules. Local modules are fundamentally coded in a local language that handles a particular local element. 

Instances of local modules will be modules for the camera, local picture picker, message pop-ups, profound connecting, and outsider administrations like Auth0 or Amplitude.

These modules should be connected with responding local connection order; however, this won’t be sufficient in the more significant part of the cases. The engineer should adhere to explicit guidelines to interface the local module to chip away at the two iOS and Android.
