ObjC NSLog not printing in Xcode console when UITesting iOS11

So have UITesting target that launches an app written in mixed ObjC and Swift code.

When running the app target normally, Swift's print() and ObjC's NSLog() statements print to the Xcode console fine on all devices and simulators.

But when running the app through the UITest the ObjC logs don't print in iOS 11, only the swift print() is logging.

Both print fine in iOS 10 and 9 in all cases.

Any ideas?

Just curious... What happens if you use C's `printf()` from your Objective-C code? – Nicolas Miari Oct 27 '17 at 05:15
@NicolasMiari Just checked, it prints – Alexandre G Oct 27 '17 at 09:07
Your don't happen to have one of those `#define NSLog(x) some-noop` for release builds, do you? – Nicolas Miari Oct 27 '17 at 09:08
@NicolasMiari I do, but it's only for release builds, and I've tried disabling it to no avail. – Alexandre G Oct 27 '17 at 12:19
I’m not sure if UI testing runs on release configuration either, but can’t think of anything else... – Nicolas Miari Oct 27 '17 at 13:08
@NicolasMiari You can choose in settings, and it's set to debug - I checked removing the `#define NSLog...` just as a sanity check.. Tred this on another computer by the way, same story! Will try with a new project on Monday. – Alexandre G Oct 28 '17 at 01:03
