[swift-users] Serious Issue with Project Preprocessor Build Setting, Xcode 7.3 and Swift.

[James Campbell]

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.
