Because it’s not an Obj-C compiler?
I suspect that the reason you saw the “incomplete” behavior is that you
declared the enum in two parts:

Under this theory, Swift is able to parse the typedef, so it knows that
‘McpSweepState’ is a type, and maybeeven an enum, but it doesn’t know what the
values are. That might be enough to let it assign, but not to compare (since ==
is not a built-in operator).
Or, it might be that it can parse the enum, but it doesn’t know its underlying
type, since you didn’t say ‘enum McpSweepState : NSUInteger’ or some such.
Honestly, though, I don’t see why you can’t just deal with writing enums the
“compatible” way.
