Since a few weeks now I haven't been able to deploy and execute apps on iPhone simulator running on iOS 11.1. The problem seems related to XCode or, possibly, MacOS because I get the same error when I try deploy from XCode (using Swift). This is the error message I get:
Unable to lookup service com.apple.CoreSimulator.host_support: 0x3
I have tried running on iOS 10.0 and also 11.1 on iPhone 6 and that works fine. But iPhone 8 or 7 on 11.1 yields this error.
Can someone help me decrypt the error message (Google came up empty).
