This is a brief post about getting started with React Native in iOS. I will walk you through the steps for running your first react native app in an iOS simulator. These steps are also present directly on react native’s official website. The reason of this post is that I will be using this post as a part of a guide that I am looking forward to make for developing an app from scratch. I shall put down all the obstacles I face with the solutions so that it makes it easier for you guys. Now let’s get started.
Development OS: macOS
Target OS: iOS
Step 1- Installing dependencies
Run the following commands in the terminal one after the other:
brew install node
npm install -g react-native-cli
Step 2- Installing XCode
The best way to install Xcode is via the Mac App Store. Once you install Xcode, it will also install the iOS Simulator and all the necessary tools to build your iOS app.
If you have already installed Xcode on your system, make sure it is version 8 or higher.
Step 3- Installing XCode command line tools
Once you are done installing XCode, open it and choose ‘Preferences’ from the XCode menu. Go to Locations and then from the Command Line tools dropdown, select the latest XCode version and install it.
Step 4 – Creating a new Application
Let’s create an application called TestApp. In the terminal, navigate to the desired location and run the following command:
react-native init TestApp
The above command will create a new react native application for you named as TestApp.
Step 5 – Running your application
This will load your iOS simulator shortly and will show the following default screen.
That’s it. You are good to go, your first react-native iOS app is successfully running on a simulator now. Stay connected for more.
