Description
I find the exhaustive enum warnings from the compiler super helpful. It ensures that whenever a new enum case is added, every switch statement is updated. But this won't work well with default. Often times the default is there as an easy way to group behaviour for the other cases at the time. I'd like to see this added as a warning

The issue does not identify a file, test, or entry point. Start by locating SwiftLint's existing enum and switch diagnostics, then determine how a default case should be reported and which cases should be exempt. Done means the warning is emitted for the intended default usage and covered by tests.
