Before we start coding, we will have to setup the environment.
Step 1: Install Xcode
What is Xcode?
Xcode is an integrated development environment built by Apple which contains a suite of software development tools that can be used to develop software for their operating systems such as iOS, WatchOS, macOS or tvOS.
Xcode can be found in the Apple App Store. The current version is 4.55GB and it might take a while to download depending on your internet connection.
Step 2: Install Homebrew

Step 4: Install Watchman

Watchman is a tool built by Facebook for watching changes in the filesystem. It is highly recommended you install it for better performance.
To install it, all you have to do is to type: brew install watchman in your Terminal then press Enter.
Step 5: Install React Native project generator
In your Terminal type: npm install -g react-native-cli and press Enter.
If installed successfully, It should look like this:
Now let’s create our first React Native Project. In your terminal type:
react-native init myFirstProject .
In the project which was just created, go to the iOS folder and double-click on myFirstProject.xcodeproj file.
This will open the iOS project in Xcode. Once Xcode started, click on the Build button to open the project in the Simulator.
