os_log compile time (build time) errors

Question

If I use ANY of the new os_log APIs that were debuted with iOS 10 / Xcode 8 / macOS 10.12, I run into a compile time error

Implicit declaration of function 'os_log' is invalid in C99

I'm using Xcode 8, and my machine is running the latest version of macOS (non-beta), developing for iOS 10.1

Any idea what gives?

You need to include the

<os/log.h>

header.

#include <os/log.h>
