OS X 10.9.2. Xcode 5.1.1. Downloaded the Apple Sample code for Audio Units. Built the “Filter” example
1. The FilterDemo target was not copying the CocoaUI target into the bundle. No UI.
CocoaFilterView bundle is indeed copied to the built Filter.component. Have you opened the Filter.component bundle and checked?
2. The project was set to bulld for Standard Archictectures only - and thus could not be seen by auval
Yes, 64-bit is "current" not to mention testing fat is more complicated than testing a single arch at a time. So, up to you to change project settings to what you want to do. This is very easily done.
On 10.9 you will see auval and auvaltool. auval is just a script that takes arguments to run auvaltool in either arch. If you have no args auval shows only 32bit AUs. Use -64 and you'll see 64-bit AUs.
3. Changing this to Universal (32/64-bit Intel) now allows the “Filter” demo to be seen in AULab.
4. You can not test this plug-in in AU Lab.
You certainly can, make a copy of the AULab app (or not). Get Info. Uncheck "Open in 32bit".
From what I can tell, this sample builds fine and works as expected in 64-bit AULab and in auval, so I'd check your setup again.
If you want to built fat or just 32bit, change the project settings and then ensure you know what you're testing. Xcode 5.1.1 does ask you to update project settings and now complains about 2 unused vars. where it never use to, but this isn't critical stuff at all. We have an update for this suite of samples planned shortly adding another AU example and update for the current version of Xcode (whatever that will be when we ship the update).
