In my work MacBook on Monterey 12.1, /private is read only, but /tmp still is
writeable. I just create a folder there as a test.
That aside, if there’s anything I’ve learned in the week or two since I’ve been
using Xcode, it’s “don’t do what it doesn’t expect you to do”. That includes
to using the default location for derived data, which is
~/Library/Developer/Xcode/DerivedData.
Just my wild assed guess & inclination.
Cheers,
Alex Zavatone
