The reason this wouldn't have been considered intentional is because it
only works for targets with bridging headers. Frameworks? Nope. Pure Swift
targets? Nope.

Ahh. Yes, we were. We would define the macro in Clang, then when we do a
lookup we'd get it back out in Swift. I, um, wouldn't have considered that
intentional, but clearly people are depending on it. Sorry, James!
Doug, we saw a similar issue with macros in bridging headers, right? Do
you remember which that was? Do you have an opinion here?

Jordan, did something change here? Were we previously getting these via
the Clang importer in a way we aren't anymore?

I've just attached one now. The preprocessor macro is specified in the
build settings.
In Xcode 7.2 these were imported and worked like they did in C i.e
API_VERSION=2 would be imported as a constant named API_VERSION and would
be a 2
In Xcode 7.3 it broke.

Swift has never supported referring directly to macros, it only supports
"build configurations". I'm still not sure exactly what you have that could
have worked previously.
Can you please attach a complete project showing something which worked
in 7.2 and does not work now to the bug you filed?

To hold keys and api endpoints.
In the past for Objective-C I would have used it like this:
request.api_endpoint = MY_MACRO_ENDPOINT
And then when Swift was released I was able to do it in Xcode 7.2:
request.api_endpoint = MY_MACRO_ENDPOINT
But when using Xocde 7.3 I get this:
request.api_endpoint = MY_MACRO_ENDPOINT //MY_MACRO_ENDPOINT not defined.

Ok, and exactly how are you trying to use them? Via an if in C or via
an if in Swift?

If I write the Macros in the bridging header they are imported but I
would ideally like to keep them in a build setting.

To follow on to what Joe said, can you provide more info about the
exact problem. Is this a C preprocessor definition that you expect to be
available in code imported by the Clang importer (i.e., bridging header
files, etc.), or is a a macro you are expecting to use within Swift itself?
And please let us know exactly which build setting you are referring to.
Thanks,
