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.

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

There are multiple ways to achieve this   By using --simulator flag By using --udid flag  Firstly you need to list all the available devices  To list all the devices run xcrun simctl list device  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       iPhone 8 Plus  5A694E28-EF4D-4CDD-85DD-640764CAA25B   Shutdown       iPhone 11  D6820D3A-875F-4CE0-B907-DAA060F60440   Shutdown       iPhone 11 Pro  B452E7A1-F21C-430E-98F0-B02F0C1065E1   Shutdown       iPhone 11 Pro Max  94973B5E-D986-44B1-8A80-116D1C54665B   Shutdown       iPhone SE  2nd generation   90953319-BF9A-4C6E-8AB1-594394AD26CE   Booted       iPad Pro  9 7-inch   9247BC07-00DB-4673-A353-46184F0B244E   Shutdown       iPad  7th generation   3D5B855D-9093-453B-81EB-B45B7DBF0ADF   Shutdown       iPad Pro  11-inch   2nd generation   B3AA4C36-BFB9-4ED8-BF5A-E37CA38394F8   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       Apple TV 4K  at 1080p   D55F9086-A56E-4893-ACAD-579FB63C561E   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   To run using --simulator run   npx react-native run-ios --simulator  quot iPhone SE quot    To run using --udid flag run   npx react-native run-ios --udid 90953319-BF9A-4C6E-8AB1-594394AD26CE  I hope this answer helped you
