TypeError: Cannot read property 'devicetypes' of undefined

I'm getting the following message when running "ios-sim showdevicetypes":

TypeError: Cannot read property 'devicetypes' of undefined

In case it helps:
The ios-sim version is "ios-sim/9.0.0 darwin-x64 node-v13.11.0".
Node version is "v13.11.0".
macOS Catalina, Xcode 11.3.1.

Thanks :)

Maybe you can check whether the command line tool for Xcode is specified:
Xcode -> Preference -> Locations -> Command Line Tools.
For my case, it is empty by default, and the simctl command used by ios-sim causes the error.

I updated to Xcode 11.4 and started running into this issue.

It looks like the JSON output of xcrun simctl list runtimes --json was changed to include an isAvailable property:

❯ xcrun simctl list runtimes --json
{
  "runtimes" : [
    {
      "bundlePath" : "\/Library\/Developer\/CoreSimulator\/Profiles\/Runtimes\/iOS 12.4.simruntime",
      "buildversion" : "16G73",
      "runtimeRoot" : "\/Library\/Developer\/CoreSimulator\/Profiles\/Runtimes\/iOS 12.4.simruntime\/Contents\/Resources\/RuntimeRoot",
      "identifier" : "com.apple.CoreSimulator.SimRuntime.iOS-12-4",
      "version" : "12.4",
      "isAvailable" : true,
      "name" : "iOS 12.4"
    },
    {
      "bundlePath" : "\/Applications\/Xcode.app\/Contents\/Developer\/Platforms\/iPhoneOS.platform\/Library\/Developer\/CoreSimulator\/Profiles\/Runtimes\/iOS.simruntime",
      "buildversion" : "17E255",
      "runtimeRoot" : "\/Applications\/Xcode.app\/Contents\/Developer\/Platforms\/iPhoneOS.platform\/Library\/Developer\/CoreSimulator\/Profiles\/Runtimes\/iOS.simruntime\/Contents\/Resources\/RuntimeRoot",
      "identifier" : "com.apple.CoreSimulator.SimRuntime.iOS-13-4",
      "version" : "13.4",
      "isAvailable" : true,
      "name" : "iOS 13.4"
    },
    {
      "bundlePath" : "\/Applications\/Xcode.app\/Contents\/Developer\/Platforms\/AppleTVOS.platform\/Library\/Developer\/CoreSimulator\/Profiles\/Runtimes\/tvOS.simruntime",
      "buildversion" : "17L255",
      "runtimeRoot" : "\/Applications\/Xcode.app\/Contents\/Developer\/Platforms\/AppleTVOS.platform\/Library\/Developer\/CoreSimulator\/Profiles\/Runtimes\/tvOS.simruntime\/Contents\/Resources\/RuntimeRoot",
      "identifier" : "com.apple.CoreSimulator.SimRuntime.tvOS-13-4",
      "version" : "13.4",
      "isAvailable" : true,
      "name" : "tvOS 13.4"
    },
    {
      "bundlePath" : "\/Applications\/Xcode.app\/Contents\/Developer\/Platforms\/WatchOS.platform\/Library\/Developer\/CoreSimulator\/Profiles\/Runtimes\/watchOS.simruntime",
      "buildversion" : "17T256",
      "runtimeRoot" : "\/Applications\/Xcode.app\/Contents\/Developer\/Platforms\/WatchOS.platform\/Library\/Developer\/CoreSimulator\/Profiles\/Runtimes\/watchOS.simruntime\/Contents\/Resources\/RuntimeRoot",
      "identifier" : "com.apple.CoreSimulator.SimRuntime.watchOS-6-2",
      "version" : "6.2",
      "isAvailable" : true,
      "name" : "watchOS 6.2"
    }
  ]
}

This breaks findRuntimesGroupByDeviceProperty which determines if a runtime is available by checking if availability equals the string (available).

Actually, it looks like this was already fixed in the latest 9.0.0 release. I was still using 9.0.0-dev.4. Updating to the latest version fixes my issue.

[eastling]

in my cases,until I allow command line in Xcode-perferences-locations, I fix it

[vilakshangithub]

I am already using the 9.0.0 release (ios-sim/9.0.0 darwin-x64 node-v11.4.0)
but I am still facing the same issue.
I am using Mac 10.14.x and verified whether xcode is installed or not using the following command

which g++
O/P:- /usr/bin/g++

Please suggest

I think I am having the same issue, running ios-sim/9.0.0 darwin-x64 node-v13.8.0 with Xcode 11.5

Command line tools preference in Xcode is set to Xcode 11.5

[miligithub]

You might need to print-path and make sure Xcode is being used and NOT Command Line Tools.

$ xcode-select --print-path
/Library/Developer/CommandLineTools
$ sudo xcode-select -s /Applications

Now do print-path again and you would see

$ xcode-select --print-path 
/Applications/Xcode.app/Contents/Developer
