I created new react native project using Expo Xde. And I run in ios simulator it works fine.
After that I installed React Native Kitten from https://akveo.github.io/react-native-ui-/#/docs/quick-start/getting-started using
npm install --save react-native-ui-kitten
Once react native ui kitten is installed I get following error in Expo XDE.
Error running `xcrun simctl openurl booted exp://localhost:19000`: An error was encountered processing the command (domain=NSPOSIXErrorDomain, code=60): The operation couldn’t be completed. Operation timed out Operation timed out 4:38:43 PM Error installing or running app. Error: Process exited with non-zero code: 60
