Won't build -- No entry point for COnversion View Controler

iOS Programming: The Big Nerd Ranch Guide (6th Edi 5. View Controller

I’m working on chapter five and I have added the MapKit. I get an error “Conversion View Controller” is unreachable because it has no entry point.

At this point, the app no longer builds–it won’t even try to build. Have I left something out?

It also appears that the linking to the Mapkit is now found under Build Phases and not the General tab. In fact, there no longer appears to be a General tab to select.

I’m using the latest version of XCode 9.1, has there been a change?

Pay no attention to this. Apparently, XCode got itself into some sort of crash and was hung on something. I had to force quit and after a restart everything was fine.
