expo build ios

What is "expo build ios"?

If you are a mobile app developer, then you must have heard about Expo. It is a free, open-source platform for building native iOS and Android apps using JavaScript and React Native. Expo has made the app development process much easier by providing a set of pre-built components and tools to developers.

"expo build ios" is a command that is used to build an iOS version of your Expo app. When you run this command, Expo will generate an IPA (iOS App Store Package) file that you can use to publish your app on the App Store.

How to use "expo build ios"?

Before running the "expo build ios" command, make sure you have set up the necessary credentials and configured your app.json file properly. You can follow the steps mentioned in the official Expo documentation to do this.

Once you have done that, open your terminal and navigate to the root directory of your Expo project. Then run the following command:

expo build:ios

This will start the building process and create an IPA file for your app. Depending on the size of your app, this process can take anywhere from a few minutes to an hour.

When the build process is complete, Expo will provide you with a download link for your IPA file. You can use this file to publish your app on the App Store using Xcode or any other iOS app distribution platform.

Alternate ways to build an iOS version of your Expo app

There are a few other ways to build an iOS version of your Expo app, depending on your requirements:

  • Using EAS Build: EAS (Expo Application Services) is a new service introduced by Expo that provides a faster and more reliable way to build and publish your Expo app. With EAS Build, you can build your app in the cloud without having to set up any credentials or configure any files. You can simply run the "eas build" command and get an IPA file for your app. However, this service is currently in beta and requires an invitation from Expo.
  • Building locally: If you want more control over the build process or if you have custom native modules in your app, you can build your app locally using Xcode. To do this, you need to first eject your Expo app and then follow the steps mentioned in the official React Native documentation for building an iOS app.

Whichever method you choose, make sure you test your app thoroughly on different iOS devices and versions before publishing it on the App Store.
