Seems really odd to me but I seem to be suddenly getting the old au rez error since having upgraded to Xcode 7.
I'm using the Projucer on an indie license. I understand that the Core Audio/Audio Unit classes are now bundled/included in JUCE so I shouldn't be worrying about patching/setting up the audio unit files anymore.
Any ideas why I might suddenly be getting this old error again ? Haven't seen it for some time and thought this was all solved.
I can locate the Core Audio SDK and relevant files when navigating through my modules folder.
I moved my modules folder to a different directory and the paths are resolving....Xcode didn't seem to be able to resolve the path I've always used previously. Bizzare.
For iOS you'd need an AudioUnit 3 plug-in, which is something that JUCE doesn't support. We are working on it now. I can't promise any release dates here, since there are a few technical obstacles to overcome, but if all goes well we might have something in a couple weeks.
