Xcode Debug Scheme

Question

I have debug scheme set up and the DEBUG flag set to 1 on my preprocessor macros, but when I set up something like this:

func print(_ object: Any) {
#if DEBUG
    Swift.print(object)
#endif

}

it is not printing even in debug mode. How would I go about correcting this behavior?

Answer 1

Go to Build Settings and add -D DEBUG to Other Swift Flags.

Then this will work properly:

#if DEBUG
    print("This is DEBUG")
#else
    print("This is not DEBUG")
#endif
