In my project's build directory there is a SharedCaches folder which I understand is where the precompiled headers are cached. I have noticed though there are quite a few folders with a variety of modification dates. Is it safe to remove all but the most recent one or will Xcode get confused? [...]
It's safe to remove any and all of them. Xcode will automatically purge older ones when the cache exceeds 1Gb in size, and will rebuild missing precompiled headers as needed.

Before it reaches that stage it might already have caused data loss on some developers machines, hidden a huge temp file in a hard to find location and forced an reboot. At least on my laptop before an yet another harddisk upgrade when it had 1.5 GB free on one of two system partitions after boot. Neat combination with the (nearly always) grow-only VM implementation.

IMO documentation for this deviation from Apples own guidelines (*) should be in a very prominent location in the XCode documenation.
