We are trying to use xcodebuild to build our frameworks, instead of using manual Xcode IDE running buttons. The issue is that in our framework we use ACTIVE_COMPILATION_CONDITIONS, which have several values. Those values are then used to check at runtime if the particular framework is integrated, like checking for Sentry:

#if SENTRY_AVAILABLE
    import Sentry
#endif

The problem is that, for some builds, we need to override our project settings, specifically ACTIVE_COMPILATION_CONDITIONS. However, after the following script successfully executes, the Xcode still does not override our provided ACTIVE_COMPILATION_CONDITIONS with defined in the project.

The script:

xcodebuild -workspace project.xcworkspace -scheme SDKNR1 ONLY_ACTIVE_ARCH=NO 
EXCLUDED_ARCHS=arm64 ACTIVE_COMPILATION_CONDITIONS=SENTRY_AVAILABLE -configuration 
release -derivedDataPath $PROJECT_DIR/../simulators/SDKNR1 -sdk iphonesimulator
ENABLE_BITCODE=YES BITCODE_GENERATION_MODE=bitcode OTHER_CFLAGS="-fembed-bitcode" clean build

As you can see we define ACTIVE_COMPILATION_CONDITIONS=SENTRY_AVAILABLE, however it will not override target's (SDKNR1) project settings. Suppose, SDKNR1 does not have any ACTIVE_COMPILATION_CONDITIONS. We expected that xcodebuild command would override target's ACTIVE_COMPILATION_CONDITIONS and would include SENTRY_AVAILABLE

Would welcome any ideas, or perhaps it is not possible?

Answer 1

The proper build setting key is "SWIFT_ACTIVE_COMPILATION_CONDITIONS"

You can double check this by using the command and verifying the key exists:

xcodebuild -showBuildSettings <project/scheme/target/configuration flags>
