React Native, a popular framework developed by Facebook, allows developers to build mobile applications using JavaScript and React. With React Native, you can create cross-platform apps that run on both iOS and Android from a single codebase. In this article, we'll guide you through the process of building an iOS app with React Native, covering everything from setup to deployment.

Why Choose React Native for iOS Development?

1. 1. Cross-Platform Development: Write once, run on both iOS and Android, saving time and resources.

   2. Rich Ecosystem: Access to numerous libraries and components to speed up development.

   3. Hot Reloading: See changes in real-time without restarting the app.

   4. Community Support: Benefit from a large and active community of developers.

Prerequisites

Before you start, ensure you have the following installed:

1. 1. Node.js: JavaScript runtime environment.

   2. npm or Yarn: Package manager.

   3. Xcode: Integrated development environment (IDE) for macOS.
