About a week ago the sample code got a refresh. I thought I’d download and have a quick look just to see what minor things may have changed. Unfortunately, the description page simply says “Adopt Swift 2.2 language changes” and there’s no mention of OS X SDK in Build Requirements. But this update adds a ton of great stuff. I know a lot of people have been asking for some of these things in the CA forum. It adds an iOS AU instrument target and all new OS X targets (this includes, AU effect, AU instrument and AU Host).
It even modifies how parameter ramping is handled. Which looks like may solve the issue I was having (https://forums.developer.apple.com/thread/35504).

Thanks Core Audio team for this update!
