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.

;)
