How to choose which iPhone model simulator to run my react native app?

Question

I am working on react native app, and I do testing on iOS Simulator.

However, it always runs on iPhone 6, and i don't know how I can switch to other iPhone models like iPhone 6 Plus or 5.

I can start a different device manually by going to Simulator -> Hardware -> Device -> iOS -> iPhone 6 Plus.

But the app is installed only on iPhone 6, and it always starts iPhone 6 when I run react-native run ios.

How can I change it so that I can run the app on different iOS Simulator devices?

Answer 1

react-native run-ios --simulator="iPhone 6s Plus"

As far as I can tell there is currently no way to specify the OS.
