I am facing same issue.

1. you can simply solve by passing something like react-native run-ios --simulator="iPhone X" with the version of the device that you need
2. you are using Xcode 10, which is not yet fully supported -> ☂️ Supporting Xcode 10 and the new Xcode build system #19573

Actually, this is already fixed via 6d09df5

This Fix also correct all simulators startup:

• Xcode 10 simulator list Fix 1031872

[kelset]

yup, I'm going to cherry pick both for the next 0.57.x release

I'm having same issue on macOS Mojave after manually downgrading XCode & Command Line Tools to 9.4 from here.

xcrun --version gives 43 and xcrun simctl list --json devices shows then newer isAvailable syntax.

This is after removing any standalone tools via sudo rm -rf /Library/Developer/CommandLineTools

I can still build manually from XCode, but can't start via react-native run-ios.

All that to say, @kelset pretty please cherry pick soon :)

@elzii 0.57.3 was released 3 days ago and has both commits.
