When I run this command:

react-native run-ios

My app runs by default in the iPhone6 simulator device:

Found Xcode project RN.xcodeproj
Launching iPhone 6 (9.2)...

How can I have the app run in a different simulator device (like iPhone5s) by default?

Specify a simulator using the --simulator flag.

These are the available devices for iOS 14.0 onwards:

npx react-native run-ios --simulator="iPhone 8"

I had an issue with XCode 10.2 specifying the correct iOS simulator version number, so used:

react-native run-ios --simulator='iPhone X (com.apple.CoreSimulator.SimRuntime.iOS-12-1)'

Here is new path for changing iOS simulator you just need to change

default: 'iPhone 6' or something else 

Path:

/node_modules/@react-native-community/cli/build/commands/runIOS/runIOS.js

You can also use npm for this by adding an entry to the scripts element of your package.json file. E.g.

"launch-ios": "react-native run-ios --simulator \"iPad Air 2\""

Then to use this: npm run launch-ios

If you want to change default device and only have to run react-native run-ios you can search in finder for keyword "runios" then open folder and fixed index.js file change 'iphone X' to your device in need.

Я разработал для этого инструмент командной строки. Вы можете просто ввести "rndcli". И выбрать устройство.

https://github.com/nazrdogan/rndcli

change line code of /node_modules/react-native/local-cli/runIOS/findMatchingSimulator.js

line 55

  if (
    simulator.availability !== '(available)' &&
    simulator.isAvailable !== true
  ) {
    continue;
  }

replace which:

   if (
                simulator.availability !== '(available)' &&
                simulator.isAvailable !== true
              ) {
                continue;
     }

You can create an alias at your ~/.bash_profile file:

alias rn-ios="react-native run-ios --simulator \"iPhone 5s (10.0)\""

And then run react-native using the created alias:

$ rn-ios

There is a project setting if you hunt down:

{project}/node_modules/react-native/local-cli/runIOS/runIOS.js

Within there are some options under module.exports including:

options: [{ command: '--simulator [string]', description: 'Explicitly set simulator to use', default: 'iPhone 7', }

Mine was line 231, simply set that to a valid installed simulator and run react-native run-ios it will run to that simulator by default.

1) Rename your simulator, If simulator with same name but different iOS version

Xcode -> Window -> Devices and Simulators -> Simulators.

enter image description here

2) Open your react native project folder

3) Edit package.json

"scripts": {
    "start": "node node_modules/react-native/local-cli/cli.js start",
    "test": "jest",
    "flow": "node_modules/.bin/flow",
    "start-iphone6": "react-native run-ios --simulator \"iPhone 6 11.3\""
}

4) npm run start-iphone6

As answered by Ian L, I also use NPM to manage my scripts.

Example:

{
  "scripts": {
    "ios": "react-native run-ios --simulator=\"iPad Air 2\"",
    "devices": "xcrun simctl list devices"
  }
}

This way, I can quickly get what I need:

  1. List all devices: npm run devices
  2. Run the default simulator: npm run ios

1st case:
It happened on a login screen, where I had autoFocus on an TextInput. Commented that out and everything went back to normal.

2nd case:
With Expo!

After an update of XCode I was getting always the iPhone 12 Max simulator, but I prefered the iPhone 8. So here are the steps I took:

  1. While simulator on focus, go to File -> Open Simulator and choose the one you wish to be the default.
  2. Close the old simulator, close the localhost:19002 and stop the server in your terminal with ctr + C.
  3. Run npm start and then press i.

Now it's running on the simulator you left open.

Happy coding!

for iPhone Xʀ Simulator

    "iosxr": "react-native run-ios --simulator=\"iPhone Xʀ\"",

just add this to your scripts in package.json file

the letter "ʀ" used here is a different Unicode than "R"

then hit $ yarn iosxr to launch the app on iPhone Xʀ Simulator

Есть несколько способов добиться этого:

  1. By using --simulator flag
  2. By using --udid flag

Firstly you need to list all the available devices. To list all the devices run

xcrun simctl list devices

This will give output as follows:

These are the available devices for iOS 13.0 onwards:

== Devices ==
-- iOS 13.6 --
    iPhone 8 (5C7EF61D-6080-4065-9C6C-B213634408F2) (Shutdown)

    iPad Pro (12.9-inch) (4th generation) (DBC7B524-9C75-4C61-A568-B94DA0A9BCC4) (Shutdown) 
    iPad Air (3rd generation) (03E3FE18-AB46-481E-80A0-D37383ADCC2C) (Shutdown) 
-- tvOS 13.4 --
    Apple TV (41579EEC-0E68-4D36-9F98-5822CD1A4104) (Shutdown) 
    Apple TV 4K (B168EF40-F2A4-4A91-B4B0-1F541201479B) (Shutdown)

-- watchOS 6.2 --
    Apple Watch Series 4 - 40mm (D4BA8A57-F9C1-4F55-B3E0-6042BA7C4ED4) (Shutdown) 
    Apple Watch Series 4 - 44mm (65D5593D-29B9-42CD-9417-FFDBAE9AED87) (Shutdown) 
    Apple Watch Series 5 - 40mm (1B73F8CC-9ECB-4018-A212-EED508A68AE3) (Shutdown) 
    Apple Watch Series 5 - 44mm (5922489B-5CF9-42CD-ACB0-B11FAF88562F) (Shutdown) 

Then from the output you can select the name or the uuid then proceed as you wish.

  1. To run using --simulator run:
npx react-native run-ios --simulator="iPhone SE"
  1. Для запуска с использованием --udidфлага run:
npx react-native run-ios --udid 90953319-BF9A-4C6E-8AB1-594394AD26CE

I hope this answer helped you.
