Not Nicholas, but I thought I’d share one of my use cases.
I use a enum (with a Int raw value) for sections in a table view, so whenever
the table view asks for the number of rows I pass in the number of cases.
Currently, I’m doing something like this:
enum Sections: Int {
case section1: 0
case section2
case section3
case _count
}
Obviously, this cases issues in switch statements since I need to handle the
_count case with an assertion, but other than that it works rather well.
