Conditional Compilation - Check Scheme

问题

In a Swift project before I've been able to perform a simple compiler check to see which scheme is running, then conditionally include code or not. For example:

#if MyScheme
    Add code here
#endif

But for some reason, in my Objective-C project, this doesn't seem to be working. Should this work the same way? Or does the Swift compiler have some advancements which allow this kind of behaviour?

回答1:

Use #ifdef

//example for debug scheme
#ifdef NDEBUG
   Add code here
#endif

And you can define your preprocessor macros here

Hope this helps
