well it would, = takes an lvalue of a type and a type, which is what the error message says you have. You’d have thunk == would be smart enough to do the same but clearly it’s not or else they aren’t really the same type, but two different types with the same name or they aren’t enums which have == automagically defined on them (as long as they don’t have associated types).

oh dear you do have some major borkage there. I have no idea what’s going on. Kind of looks like the enum didn’t bridge over as an enum but some other type which doesn’t conform to ‘==‘. Perhaps the typedef of the name 'enum XXX' to ‘XXX' upsets it.
Only other thought I have is to change the original version to
typedef NS_ENUM( NSInteger, McpSweepState )
{
// your enum values here
}
but I’m not entirely sure I hold out much hope for that either.
