For building an iOS app but don't want to invest the time and resources into learning Swift or Objective-C, React Native is a great option. React Native is a cross-platform framework that allows you to use JavaScript to develop native mobile applications. In this article, we'll go over best practices for react native build app for IOS.

So, if you're planning on developing an iOS app in React Native, what are some of the best libraries to use? Here are some of our favorites.

1. Use TypeScript

If you're going to be building your app in JavaScript, you might as well use a superset of the language that provides static type checking. That's where TypeScript comes in. TypeScript is a free and open-source programming language developed and maintained by Microsoft. It adds optional static typing to JavaScript and can be used with various tools, such as Babel, to transpile your code down to vanilla JavaScript that can run on any platform.

While TypeScript isn't required to react native build app for IOS, it makes the development process easier—especially if you're coming from a statically typed language like Java or C#. With TypeScript, you'll catch errors during development instead of after you've deployed your code, which will save you time and headaches down the road.

2. Use Genymotion for Emulation

If you're going to be developing your app on a Windows PC, the Android emulator that ships with the standard installation of Google's Android Studio won't be much help. That's because the default Android emulator is painfully slow—bordering on unusable. Instead, what you'll want to do is download and install Genymotion.

Genymotion is one of the best Android emulators on the market. It's fast, reliable, and easy to use. Plus, it has a free trial period so that you can make sure it works with your development environment before investing any money in it. Once you've installed Genymotion, setting up virtual devices is a breeze. Just select the device you want to emulate—whether it's a phone or tablet—and follow the prompts. You'll be up and running in no time!

3. Use ExpoKit

ExpoKit is a toolkit developed by Expo that allows you to take advantage of the Expo platform while still using the traditional react-native commands line interface (CLI). With ExpoKit, you have full access to all of the native APIs exposed by React Native, as well as Expo's existing APIs— giving you more flexibility when it comes to developing your app.

4. Lottie by Airbnb

Lottie is a library created by Airbnb that allows developers to easily add animations to their apps. The nice thing about Lottie is that all of the animations are created in Adobe After Effects, so they look smooth and polished. In addition, Lottie comes with a lot of built-in animations that you can use in your app without having to create them yourself.

5. React-Native-Firebase by Google

React-native-firebase is a library created by Google that allows you to easily integrate Firebase into your React Native app. Firebase is a mobile and web application development platform that provides several services such as analytics, databases, messaging, and crash reporting. By using react-native-firebase in your app, you can take advantage of all of these services without having to write any additional code.

If you're planning on submitting your app to the App Store or Google Play Store, ExpoKit is a must-have tool. That's because it allows you to opt out of using Expo's services without having to eject from the managed workflow that comes with using Expo CLI. Ejecting from managed workflows is generally considered bad practice because it makes upgrading future versions of your app more difficult—so why not avoid ejecting altogether by using ExpoKit?

6. Redux by Redux DevTools

Redux is a library created by Redux DevTools that allows you to easily manage the state in your React Native app. If you're not familiar with state management, it's something that helps you keep track of changes in your data over time. Keeping track of the state can be tricky, especially as your app grows in size and complexity. However, Redux makes it easy by providing an easy way to update and query your state data.
