native-run: Cannot run app in iOS simulator with "ERR_UNKNOWN: Unable to retrieve simulator list" error

Description: I run “ionic cordova emulate ios” in Terminal and got “ERR_UNKNOWN: Unable to retrieve simulator list” error. It worked fine with CLI v4.12.0

Output:

I had the same problem. Was using Ionic CLI v5.0.0 and had to downgrade it to v4.12.0 to get it working again =/

For those of you still getting Unable to retrieve simulator list: Cannot read property 'filter' of undefined on the latest version of native-run, can you please run the following commands and attach their output?

xcodebuild -version xcrun simctl list devices --json

If you can provide any details about having multiple versions of Xcode, or when you upgraded and from which version, that would also be very helpful.

I’ve gotten at least one report that someone is seeing the old simctl device format (ex: iOS 12.1) using Xcode 10+ and I am unable to reproduce the issue (switching to Xcode 10+ changes the device format to the identifier format 12.1 -> com.apple.CoreSimulator.SimRuntime.iOS-12-1)

Thanks!

Can you guys update to the latest version (npm install -g native-run) and post your output please? There have been a few fixes and there should be better output for simulator errors, thanks!

@tlancina turned out my npm install was corrupted and my update attempt didn’t work. I was on 0.2.2 native-run, sorry for wasting your time and thanks for the answer 👍

@tlancina 0.2.6 fixed my problem, thanks again! 🎉
