Issue Description:

It appears that a NSObject subclass with the @objcMembers and a bool property fail to build on Linux. Commenting out the @objcMembers annotation, and it builds fine. Likewise, leaving the @objcMembers annotation on there and changing the bool property to an int property, also compiles fine.

<unknown>:0: error: could not find Objective-C bridge type for type 'Bool'; did you forget to import Foundation?
<unknown>:0: error: fatal error encountered during compilation; please file a bug report with your project and the crash log
<unknown>:0: note: unable to set up the ObjC bridge!

Is there any way to workaround this? I've tried

#if os(iOS) @objcMembers #endif

without any luck.

I don't think you're even supposed to use @objcMembers on Linux, but that puts this in the same camp as SR-3332.

Yeah, I mean I don't need the objc stuff in Linux obviously, but I'm using the same code on iOS as I plan to on Linux.
