Answer 1

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.
