Summary

In this chapter, you learned how to build a release of our application in preparation for submitting it to the App Store or Google Play Store. iOS had a pre-configuration scheme in Xcode to disable the developer features. We then created an archive by targeting the iOS device. On Android, we created a private release key with keytool and built the release APK using the command line and gradle. It is important to follow up and test that both of these release builds work before submission, to decrease the likelihood of rejection.

We hope that this book gave you the fundamentals you need to start creating mobile apps with React Native. Although React and React Native are still very early in terms of development, you can expect the core concepts discussed in this book to stay relevant for some time to come. When Android finally reaches feature parity with iOS, the doors will open for a lot more rapid development between the two platforms. Good luck, and we can't wait to see your apps...
