Issue Description:

I have an error in my code with where I mistyped an enum and as a result it doesn't exist. However the Swift compiler doesn't indicate this as such and points to an issue with the ForEach loop syntax, which confused me for quite awhile. (I'm new to SwiftUI so I assumed I was just doing something silly with the ForEach and didn't bother to look lower)

Error:

Extra arguments at positions #2, #3 in call
