React Native using pre-bundled file on device, even if DEV-mode

Question

A few days ago, when I build and run my react native app from Xcode on a device, I realised that even if I set my scheme to Debug, the app is still loading from a pre-bundle

Answer 1

For those who are connected to the same Wi-Fi, but to a different IP address than localhost (you've set it up in RCTWebSocketExecutor.m):

Check Xcode debug console, if you can find the following error:

App Transport Security has blocked a cleartext HTTP (http://) resource load since it is insecure. Temporary exceptions can be configured via your app's Info.plist file.

2. And then use Codesingh's answer. BTW I recommend using the #ifdef DEBUG directive as follows, so that you don't have to change it manually when switching between build variants:

.

#ifdef DEBUG
  jsCodeLocation = [NSURL URLWithString:@"http://xxx.xxx.xxx.xxx:8081/index.ios.bundle?platform=ios&dev=true"];
#else
  jsCodeLocation = [[RCTBundleURLProvider sharedSettings] jsBundleURLForBundleRoot:@"index.ios" fallbackResource:nil];
#endif
