Cannot read property 'udid' of undefined

**Version:**

0.2.8

**Description:**

Hello
native-run doesn't see the emulator or dont create a new one. As I see DeviceList is empty. What's the problem? I am trying to solve for 2 days.

**Command Output:**

```
native-run ios --app platforms/ios/build/emulator/MyBookie.app --forward 8100:8100 --verbose
