static func define(_ name: String, _ condition: BuildSettingCondition? = nil) -> SwiftSetting Parameters
Use compilation conditions to only compile statements if a certain condition is true. For example, the Swift compiler will only compile the statements inside the #if block when ENABLE_SOMETHING is defined:
#if ENABLE_SOMETHING
...
