Run react-native application on iOS device directly from command line?

The following worked for me (tested on react native 0.38 and 0.40):

npm install -g ios-deploy# Run on a connected device, e.g. Max's iPhone:react-native run-ios --device "Max's iPhone"

If you try to run run-ios, you will see that the script recommends to do npm install -g ios-deploy when it reach install step after building.

While the documentation on the various commands that react-native offers is a little sketchy, it is worth going to react-native/local-cli. There, you can see all the commands available and the code that they run - you can thus work out what switches are available for undocumented commands.

First install the required library globally on your computer:

npm install -g ios-deploy

Go to your settings on your iPhone to find the name of the device.

Then provide that below like:

react-native run-ios --device "______\'s iPhone"

Sometimes this will fail and output a message like this:

Found Xcode project ________.xcodeprojCould not find device with the name: "_______'s iPhone".Choose one of the following:______’s iPhone Udid: _________

That udid is used like this:

react-native run-ios --udid 0412e2c230a14e23451699

Optionally you may use:

react-native run-ios --udid 0412e2c230a14e23451699 -- configuration Release

Run this command in project root directory.

1>. List of iPhone devices for found the connected Real Devices and Simulator. same as like adb devices command for android.

xcrun instruments -s devices

2>. Select device using this command which you want to run your app

Using Device Name

react-native run-ios --device "Kool's iPhone"

Using UDID

react-native run-ios --udid 0412e2c2******51699

wait and watch to run your app in specific devices - K00L ;)
