Can you try uninstalling the Expo Client from the simulator and/or reseting content and settings for your simulator? I just ran expo start --ios and my project opened with no issue and my MBP is running 10.14.2
So I tried setting up my dev environment on another MAC which is running on OS High Sierra, but running into the same issue not being able to open Expo in the ios simulator. So that rules out the OS causing the issue. Another MAC at the office with the exact same specs, setup and network is able to run the project without any issues, which is weird.
I’m also sometimes getting an error when trying to run ‘expo start’, which I feel might be related. Logs below:
[17:46:06] Could not get status from Metro bundler. connect ECONNREFUSED 127.0.0.1:19001
[17:46:06] Connecting to Metro bundler failed.

I’m starting to think this could actually be a network issue after all…
