I want to have a bool macros to enable some functionality in my app per build. For example, enable in QA builds but disable in production. For this, I added this code to my app .xcconfing file:

FEATURE_ENABLED=1

GCC_PREPROCESSOR_DEFINITIONS = $(inherited) FEATURE_ENABLED='${FEATURE_ENABLED}'

OTHER_SWIFT_FLAGS = $(inherited) -DFEATURE_ENABLED='${FEATURE_ENABLED}'

#if FEATURE_ENABLED
// do some stuff
#else
// do some other stuff
#endif

FEATURE_ENABLED is working in ObjC when I change its value, but not working in Swift at all. The question is why, and how to make it work.

    `SWIFT_ACTIVE_COMPILATION_CONDITIONS = ENABLE_FEATURE;` ? Swift flags actually don't care about the value, you cannot turn them off by setting `0`. – Sulthan Feb 01 '19 at 19:40

  • @Sulthan Thank you for the help, this does the trick for debug builds. But I need value in swift, and it seems that I should find another solution, with `.plist` probably. – Roman Simenok Feb 01 '19 at 23:17
