Cannot find entry file index.ios.js in any of the roots

Hi everyone. I have an expo based project and I need use components with platform dependent code. I did detach my project and ran it on android. It works (thank god). i also try build it on macOS and run in simulator. But no success. I get the error “Cannot find entry file index.ios.js in any of the roots” http://i.imgur.com/tQk6ib6.png
but I should not have index.ios.js using expo
I guess XCode thinks I use react-native without expo.
So if I right then my question is how to specify to XCode that I use expo?
Thank you!
