Developers, both proficient and amateur, face problems when building web or mobile applications. Today, we will talk about the common issues React Native developers face, and their solutions.

Are you a business owner or an aspiring React Native programmer? In any case, this is a must-read post. It will give an idea of how do top React Native app development companies sort out common pitfalls. Hence, you will ensure faster development for your web application or improve your skills. We will dive into these development pitfalls shortly. Before this, let us know why people love React Native.

• Why is there a surge in demand for React Native developers?

React Native is an open-source framework that enables developers to build applications compatible with multiple platforms. Besides cross-platform implementation, the constant updates drive the global demand for React Native consultants. According to Statista, it is the second most loved cross-platform framework.

The advancements in the framework have made the lives of developers easier. On the other hand, enterprises build feature-rich and high-performing applications faster. The best thing is you do not have to spend a bomb on React Native development.

Given the great perks, React Native is a preferred choice of top brands. These are Facebook, Bloomberg, Instagram, Airbnb, Ubereats, and more. All the applications have a smooth user interface and ultimate functionality. Do not forget they are user-friendly.

If you want to build an application like this, it requires skill set, experience, and in-depth knowledge. But it is normal to face challenges during the development, even for the top React Native app development companies. We are going to list the most common ones with a relevant solution.

• Best practices to solve common React Native development pitfalls

At times, React Native Developers encounter issues that may be difficult to handle. The reason could be insufficient knowledge about the same. Therefore, we have gathered commonly faced problems based on the experiences of many.

1. Creating screenshots for the Apple store

Several React Native consultants have raised the issue that they are unable to create screenshots for Apple Connect. Most of them use a simulator for testing apps built with React Native. As a result, using Xcode Simulator to create right-sized and density screenshots for the Apple Store is complicated.

On the contrary, the simulator works efficiently for creating and uploading screenshots for Google Play. The problem comes when getting the right dimension for the Apple Store.

For example, if you are building for a 6.5” iPhone, it asks for dimensions like 2688×1242 or 2778×1284. And achieving this with device emulators may not bring any success. Therefore, we have the right solution for you. We have mentioned it below:

• Firstly, set the simulator to physical size. For this, go to the Window and click the Physical Size option.
• Now, you need to set high-quality graphics. Here is what you need to do: Debug > Graphics Quality Override > High-Quality

Note:* React Native developers can employ any Pro iPhone for a 6.5” iPhone screenshot creation. For a 5.5” iPhone, iPhone 8+ simulator is an ideal solution.

2. The default fonts do not fit all projects

Another issue React Native development companies run into is default fonts. For example, React Native comes with a ‘Roboto’ font for Android, whereas ‘San Francisco’ is for iOS. But they do not meet the needs of all application projects. That means developers need to use different fonts.

One option is Google Fonts, you can apply using the package: expo install expo-google-fonts. Once you install this package, run this command:

import

{

useFonts,

Lato_400Regular,

Lato_900Black,

Lato_700Bold,

} from '@expo-google-fonts/lato';

export default function App() {

constisLoadingComplete =

useCachedResources();

constcolorScheme =

useColorScheme();

let [fontsLoaded] = useFonts({

Lato_400Regular,

Lato_900Black,

Lato_700Bold,

});

if (!isLoadingComplete ||

!fontsLoaded) {

return ;

} else {

return (

colorScheme={colorScheme} />

);

}

}

3. Rendering HTML

React Native developers can hardcore texts easily in web applications. However, making changes in a text is a time-extensive process. It means they have to create new builds. After this, they need to submit it to the app store.

If you think the challenges are limited to this, you are wrong. Some users might have disabled automatic updates for your app. So, they will not get the benefits and features of the new version until they update it. The best way the top React Native app development companies use to overcome this issue is by sending not-common texts via the API.

But this may not solve the issues related to dynamic content. How will you manage description-rich content? Unlike the backend, your app does not have a text editor for formatting the text. It calls for HTML rendering. And using react-native-render-html is the suitable solution. It is a JavaScript react-native native for iOS and Android. It allows React Native developers to render HTML into native views.

4. Endless cookies and local storage

As a React Native development company, it is likely to deal with cookies and local storage for everything. For example, if you need to save information, here are cookies. Besides this, local storage adds to the problem. Many tried to add a bearer token for Authorization and User Information Object. But it led to an empty Bearer string for each request.

Luckily, we have found a solution for you. That is installing this package: expo install react-native-async-storage/async-storage. After installing, run this code:

try {

awaitAsyncStorage.setItem('@token', result.data.token);

constjsonValue = JSON.stringify(result.data);

awaitAsyncStorage.setItem('@user_Object', jsonValue);

} catch (e) {

console.log(e);

}

try {

const value = await AsyncStorage.getItem('@user_Object');

if (value !== null) {

constuserObjectParsed = JSON.parse(value);

}

} catch (e) {

// error reading value

}

The bottom line

These are the most encountered issues by React Native developers across the globe. With these tips, you can overcome these challenges and build React Native applications with ease.

But the good thing is React Native community is growing. If you face any problem, there are plenty of packages to resolve them. In addition to this, you can reach the proficient team of React Native developers and designers for assistance.
