Is it possible to run react-native application on an iOS device directly from the command line like we do on simulator with react-native run ios --simulator "iPhone 5s"?

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 ________.xcodeproj
Could 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 --device --udid 0412e2c2******51699

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

If you get this error [email protected] preinstall: ./src/scripts/check_reqs.js && xcodebuild ... using npm install -g ios-deploy

Try this. It works for me:

  1. sudo npm uninstall -g ios-deploy
  2. brew install ios-deploy

Actually, For the first build, please do it with Xcode and then do the following way:

  1. brew install ios-deploy
  2. npx react-native run-ios --device

The second command will run the app on the first connected device.

Just wanted to add something to Kamil's answer

After following the steps, I still got an error,

error Could not find device with the name: "....'s Xr"

After removing special characters from the device name (Go to Settings -> General -> About -> Name)

Eg: '

It Worked !

Hope this will help someone who faced similar issue.

Tested with - react-native-cli: 2.0.1 | react-native: 0.59.8 | VSCode 1.32 | Xcode 10.2.1 | iOS 12.3

For you to run on specific ios device run

yarn ios --simulator "iPhone 8" if you are using yarn or
npx react-native run-ios --simulator="iPhone SE (1st generation)"
