ios - How to build .ipa for React Native?

Question

I come to React Native development without previous experience in iOS development. I want to build release. .ipa file - ideally from the command line but the official documentation Running On Device is very brief.

I was able to deploy applications on my iPhone manually via XCode but still, I can't find any "release IPA" file. I have updated my code with #ifdef DEBUG directives to make it more generic.

Is there a way to build an application in release mode only via the command-line? If no, what is "the official" way to generate an RN application?

I am currently using RN 0.20.

First, you need to create a bundle this way :

react-native bundle --dev false --entry-file index.ios.js --bundle-output ios/main.jsbundle --platform ios

Then, you have to comment this line in AppDelegate.m :

jsCodeLocation = [NSURL URLWithString:@"http://localhost:8081/index.ios.bundle?platform=ios&dev=true"];

and uncomment this one :

jsCodeLocation = [[NSBundle mainBundle] URLForResource:@"main" withExtension:@"jsbundle"];

Then you have to go for Product -> Archive in Xcode and follow the steps based on your desired release
