I’m having an issue running iOS simulator from Expo. I’m seeing these two errors:
Trying to open the project in iOS simulator... Opening iOS simulator iOS Simulator device failed to boot. Try opening Simulator first, then running your app. Error installing or running app. Error: Timed out waiting for iOS Simulator device to boot.
Trying to open the project in iOS simulator... Booting device in iOS simulator... There was a problem booting a device in iOS Simulator. Quit Simulator, and try again. Error installing or running app. Error: No iPhone devices available in Simulator
An iPhone 5s with iOS 11.2 is clearly available and works in Xcode simulator with a simple project ran from Xcode. So this is what tells me it is an Expo issue.
- Expo version: 3.4.1
- Xcode version: 9.2
- Mac OS: 10.12.6
Please note - I cannot upgrade my OS. So Xcode version 9.2 is what I must use.
Things I’ve tried:
set command line tools as correct Xcode version with path /Applications/Xcode.app
delete all simulators and re-add them
start simulator before running app / start simulator after running app
delete all contents under Library/Developer/CoreSimulator/Devices/
