This code will never be executed warning swift equatable enum

Question

I have this code from a 3rd party library:

public enum NoError: Swift.Error, Equatable {
    public static func ==(lhs: NoError, rhs: NoError) -> Bool {
        return true
    }
}

This generates the warning : 1. 'lhs' is uninhabited, so this function body can never be executed This will never be executed

How could I get rid of this warning?

Answer 1

enum should have case . I mean enumeration should have definition. I don't understand why enum uses here, because it's can be class . However, this will work without warnings:

public enum NoError: Swift.Error, Equatable {

    case case1
    case case2

    public static func ==(lhs: NoError, rhs: NoError) -> Bool {
        return true
    }
}
