I’ve an app using low level CoreAudio C functions, usually located under /Volumes/Xcode/Xcode.app/Contents/Developer/Extras/CoreAudio/PublicUtility/. Just installed Xcode 4.3.1 and iOS 5.1 and Public Utility seems gone away.
My missing files are:
CADebugMacros.h
CAMath.h
CAStreamBasicDescription.cpp
CAStreamBasicDescription.h
Anyone knows if these files have been removed from this last release or should I just copy the files from previous Xcode version?
CoreAudio Public Utility has been there since iOS 2 (at least).

Ty!

    This is explained in the Xcode 4.3 what’s new documentation.

    Choose this menu:

    Xcode > Open Developer Tool > More Developer Tools...

    and download “Audio Tools for Xcode”.
