Hi @peterjuras and thanks for your question.

Launching the "Run iOS on Simulator" target always starts the iPhone 6 simulator

To start running app extension is using react-native run-ios command. According to official React Native docs, in this case it is standard behavior:

You can specify the device the simulator should run with the --simulator flag, followed by the device name as a string. The default is "iPhone 6".

To run your app on different simulator you should create .vscode/settings.json file at the root of your project and fill it with the following content:

{
    "react-native.ios.runArguments.simulator": [
        "--simulator", "iPhone 7"
    ]
}

where iPhone 7 is the simulator name. To read more about specifying custom arguments for react-native run-* command, please, follow this documentation section.

Please let us know whether it helps you or not.
