Note that running on device requires [Apple Developer account](https://developer.apple.com/register/index.action) and provisioning your iPhone. This guide covers only React Native specific topic.

## Accessing development server from device
|
|
|
|
You can iterate quickly on device using development server. To do that, your laptop and your phone have to be on the same wifi network.
|
|
|
|
1. Open `iOS/AppDelegate.m`
|
|
2. Change the IP in the URL from `localhost` to your laptop's IP
|
|
3. In Xcode select your phone as build target and press "Build and run"
|
|
|
|
> Hint
|
|
>
|
|
> Shake the device to open development menu (reload, debug, etc.)
|
|
|
|
## Using offline bundle
|
|
|
|
You can also pack all the JavaScript code within the app itself. This way you can test it without development server running and submit the app to the AppStore.
|
|
|
|
1. Open `iOS/AppDelegate.m`
|
|
2. Follow the instructions for "OPTION 2":
|
|
* Uncomment `jsCodeLocation = [[NSBundle mainBundle] ...`
|
|
* Run the `react-native bundle` command in terminal from the root directory of your app
|
|
|
|
The bundle script supports a couple of flags:
|
|
|
|
* `--dev` - sets the value of `__DEV__` variable to true. When `true` it turns on a bunch of useful development warnings. For production it is recommended to set `__DEV__=false`.
|
|
* `--minify` - pipe the JS code through UglifyJS.
|
|
|
|
## Troubleshooting
|
|
|
|
If `curl` command fails make sure the packager is running. Also try adding `--ipv4` flag to the end of it.
|
|
|
|
If you started your project a while ago, `main.jsbundle` might not be included into Xcode project. To add it, right click on your project directory and click "Add Files to ..." - choose the `main.jsbundle` file that you generated.
