Xcode 10 simulator runtime is not available: runtime profile not found error

Question

While trying to run the simulator with iOS 11 in Xcode 10 Version 10.1 (10B61), sometimes this error occurs:

"The com.apple.CoreSimulator.SimRuntime.iOS-11-4 simulator
runtime is not available. runtime profile not found"

The 11.4 simulator runtime is an external disk and it's well connected. Maybe that happens when I connect the external disk after opening the Xcode. How can I refresh the list of the available simulator runtime profiles?

Just run

sudo killall -9 com.apple.CoreSimulator.CoreSimulatorService

to restart the Simulator service.

Do you have any insights on why this occurs? Is it an issue with `CoreSimulatorService`? – Evan R Mar 05 '19 at 18:26

@EvanR No, don't know why that happened. Sorry – ricardopereira Mar 05 '19 at 20:32

I wonder why this is not part of the install scripts on xcode updates – Yoku May 19 '19 at 17:08
